Hideo GAMO1961 Volume 8 Issue 3-4 Pages 81-82
Published: July 31, 1961
Released on J-STAGE: June 28, 2010
JOURNAL FREE ACCESSThe medaka, Oryzias latipes, a cyprinodont fresh-water teleost, which is popular in Japan and is easy for laboratory culture, is, therefore, a favorable material for embryological researches. The difficulty of sectioning embryos, however, has been hindering its histo-embryological study.
The author found a key point for solving this problem. It is not to raise the temperature of the melted paraffin for imbedding the embryos over 60°C, probably to avoid the yolk protein heat-coagulating.View full abstractDownload PDF (252K) -

JOURNAL FREE ACCESS1) The bilateral asymmetry of the gonad primordia of embryo of the medaka starts at the stage in which the gonad primordia begins to protrude into the coelome from the mesentery area. Thus the front end of the primordia protrudes only into the right side coelome because of some unknown agent.
2) The front end of the right side primordia extends forewards being caused by some unknown agent and eventually the right side turns out statistically twice as long as the left side when hatched.View full abstractDownload PDF (292K) -

JOURNAL FREE ACCESSThe determination following NICHOLS'S keys (1943) has brought following results: The specimens from Yang-tse-kiang (China) belong to Misgurnus anguillicaudatus tungting, one specimen from Nagasaki (Hondo, Japan) is believed to belong to Misgurnus mizolepis elongatus, similarly as specimens from Kyushu and Kagawa Prefecture (both in Japan). Four specimens from Hyogo and 1 sp.from Kagawa Prefecture were determined as Misgurnus mizolepis elongatus and Misgurnus anguillicaudatus anguillicaudatus.
It seems probable that the species Misgurnus anguillicaudatus can be divided in two groups, the one with a shorter, the other with a longer caudal peduncle. To the first group belong than Misgurnus anguillicaudatus with its subspecies M. anguilli caudatus anguillicaudatus and Misgurnus anguillicaudatus tungting. To the second one Misgurnus erikssoni RENDAHL 1922 and Misgurnus mizolepis with its subspecies M. m. mizolepis GÜNTHER 1888, M. mizolepis grangeri NICHOLS 1925, M. mizolepis fukien NICHOLS 1925, M. mizolepis punctatus OSHIMA 1926, M. mizolepis hainan NICHOLS et POPE 1927, M. mizolepis unicolor LIN 1932, M. mizolepis elongatus KIMURA 1934.
The intergrade between both groups is the species M. mohoity DYBOWSKI 1869, with its subspecies M. mohoity yunnan NICHOLS 1925 and M. mohoity leopardus NICHOLS 1925, M. crossochilus SAUVAGE 1878 has an unclear systematic position (see NICHOLS 1943) and according to FANG (1943) this species is identical with M. anguillicaudatus. The variability of Misgurnus anguillicaudatus, mentioned already by GÜNTHER (1868) seems to be very probable especially regarding the body depth, but the occurence of dilatation of tail “by fatty layers along the upper and lower rudimentary caudal rays ” thought by GÜNTHER (1. c.) as caused by different kinds of food is for NICHOLS (1943) a systematic character of the subgeneric rank.
The subspecific value of some forms will be probably revised in the future, when we keep the conception of BERG (1948). The occurence of two subspecies on one locality seems impossible (e. g. M. mizolepis punctatus and M. mizolepis hainan both on the island of Hainan, M. mizolepis unicolor and M. mizolepis hainan in Heung chow, M. mizolepis fukien and M. mizolepis punctatus in Fukien). It is very remark able to note that M. mizolepis hainan lives from Hainan to Heungchow (throughout the province Fukien) and M. mizolepis punctatus has approximately the same areal from the island of Hainan to the province of Fukien. We can than assume that in the same areal of Fukien according to data of NICHOLS (1943) three subspecies of Misgurnus mizolepis (fukien, punctatus, hainan) occur. This is in contradiction with the BERG'S concept of the subspecies as a geographical unit.View full abstractDownload PDF (750K) -
