    1. Eleven colour-blind subjects diagnosed as red-blind by routine procedure with Prof. Ishihara's charts were subjected to spectroscopic examination as developed by Prof. Hukuda and described in a previous report.
    2. Of 11 subjects, all male, one was trichromic, 6 tetrachromic, 2 pentachromic and 2 were hexachromic in the sense of Edridge-Green.
    3. All of them had sensation of yellow and blue. Expansion of the yellow zone to both &des, espcially toward the region of shorter wavelength was a most common feature. The green region was often sacrificed for the yellow.
    4. Of 22 eyes, 4 had no zone of defective saturation while 7 eyes were characterized with two zones of defective saturation. This trait was not always represented symmetrically in each individual.
    5. Two zones, instead of a single zone, of maximum brightness were reported by 14 eyes out of 22.
    6. The spectrum was not always shortened at its end of longer wavelength. Some subjeets were suspected of shortening atits end of shorter wavelength.

    1. An inhabitant, 19 year-old male, of Sado Island, and his sister, 16 years of age, were found to posses all conventional criteria of total colour-blindness. Spectroscopic examination, however, revealed they had more on less rudimentary colour discriminative power.
    2. The brother was dichromic, his spectrum being composed of“ darkened blue” (Up to 495mμ) and “darkened khahki” (550. 700mμ) with a zone of minimum chromaticity at 495.550mμ. The sister was found trichromit. She saw the spectral range up to 485mμ as “darkened blue”. From 485mμ to 500mμ was minimum in chromaticity. A “darkened yellow” began at 500mμ and farther ahead it blended into a “ darkened red”, which continued up, to 690mμ.
    Possibility is indicated that the totally cokiur-blind generally retain rudimentary colour sensation, since previous cases had been diagnosed as such without spectral perusal, such as performed by the present authors.
    Hereditary relation was also discussed.

    Twenty-two cases of trichromats as diagnosed by conventional technique were subjected to spectral examination in which their colour sensation in reference to wavelength in the continuous spectrum of incandescent daylight lamp was determined.
    Of the 22 male cases, one possessed a spectrum consisting of two principal colour zones, “yellow” and “blue”, i. e. dichromic in the terminology of Edridge-Green. Four proved to be tetrachromic with red, yellow, greeri and blue, or red, “orange”, blue and violet. Another four were pentachromic with red, orange, yellow, green and blue (three case), or red, “violet”, yellow, green and blue (one case). Remaining 13 cases were hexachromic with red, orange, yellow, green, blue and violet. It was then inferred that all eyes, even the dichromic were able to make out yEllow and blue ift the spectrum.
    Wave-length range of each discriminated principal colours varied from case to case. Inter-lateral difference was also present, although in a lesser extent A most markei characteristic common to all cases examined was deviation with expansion of the yellow range.
    In 4 cases among the hexachromic, point of transition between yellow and green was labile, showing fluctuation. In a case apparently normal in colour distribution in the spectrum on the first glance, yellow range expanded toward green, at a partial sacrifice of the latter in a few seconds. Four cases showed the reverse condition. Chromic feature of their spectrum at first was anomalous with an expanded yellow zone. When the gazing was continued a few seco id, the transition point between yellow and green shifted toward yellow side. Anomalous arrangement of the subjective spectrum thus resulted.
    As for subjective luminosity, 17 eyes out of 44 (22 cases) were reported to have two summit distribution.
    Twenty-nine eyes of 44 is reportei to have an unsaturated zone in the spectrum. It is generally situated in the neighbourhood of 500±5mμ.
    Some of the cases here reported, when subjectied to examination with an anomaloscope, showed a typical dichromatic pattern, while they were often found polychromic by direct spectroscopic examination, or more than two principal colour zones were differentiated.

    Fifteen atypiCal cases of colour-defectives- as diagnosed with Professor Ishihara's international pseudbchromatic charts were subjected to the authors' techniqueof spectral examination as well as anomaloscopic investigation.
    Also in these case the at there' previous observations and statements' were' con-firmed without exception.
    Conventional class fication of colour-defectives into protanopia, deuteranopia, protanomaly and deuteranomaly was not based on a sound. ground of directive investigation of phenotypes.

    1)佐渡に於て見出された色覚異常者の13家系に就て記述し,全部で72名の中8名の色覚異常者に就ては彼等個陣人の主観的スペクトルの特性を観察することを得た.
    2)8名の中で四色性(赤,黄,青,紫)のもの1名,五色性(赤,黄,緑,青,紫,または赤,橙,黄,緑,青,)のもの4名,3名は六色性であつた.五色性の中で2名は1眼に於ては緑がなく四色姓であつた.
    3)8名の主観的スペクトルに於ける各色調の対応波長範囲は,それぞれ異常であるが,特に黄の異常性は著しく,連続スペクトル中の広い範囲に拡がつている.
    4)明るさの極大部は585mμを中心したスペクトル帯に一ヵ所あるのみであつた.
    5)これらの13家系例に於ける色覚異常者の出現は色盲と色弱との遺伝子を区別しなければ従來の学説で一応説明することが出來る.しかし13家系中5家系にあつて,所謂色弱と色盲とが混合して出現しており,しかも第12家系例での遺伝関係は色盲と色弱とが別々の遺伝子に基くとするWaalerなどの学説が成り立たないことを示している.

    Six pedigrees of non-tasters were recorded and the mode of inheritance was discussed. They conform with conventional theory of simple Mendelian recessive inheritance. In a pedigree were found three (two male and a female) non-tasters of very low manifestation. Possible interpretations for this anomaly were discussed and an assumption of incomple manifestation in heterozygous subject was offered as the simplest interpretation.

    1.P.T.C.に対する味盲の家系調査を行い六つの家系を記録した.
    2.これらの家系図は劣性遺伝を是認する.優性遺伝として考えたのでは第1家系に於て1ヵ所世代の飛び越えがあるのが説明困難である.不完全優性などというような考え方でこれを説明して出來ないことはないわけであるが,殊更,味盲に対して優性遺伝を想定しなければならない根拠が他にあるわけではない.
    3.これらの六つの家系図を通覽して味盲が多発していることは事実であるが,それは必しも優性遺伝の支持とは認められない.
    4.味盲と健常者との交配によつて生れた子供には健常者が多い.このことは劣性遺伝の考え方をむしろ支持する.
    5.第1家系に特発しその子に伝わつた味盲の不全型が見出された.これの説明として種々の可能性を論じた.そして最も簡単な想定として一応,ヘテロの個体に於ける不完全な表現度という考え方を採つた.
