Since 1958, one of the authors (ABE) has noticed a close ally of Psenes cyanophrys VALENCIENNES appearing very rarely in Sagami Bay. Recently additional much larger specimens of this species have been received for study, and the specimen upon which undoubtedly the record of Psenes cyanophrys by Dr. KAMOHARA (1942) was based has been sent on loan from the Seto Maine Biological Station, Kyoto University. Further, a radiograph of the type specimen of Psenes cyanophrys VALENCIENNES has been received through courtesy of Prof. J. Guist and Dr. M. BLANC. Although there remains much to be studied about the change of the dentiton with growth and the: individual variation in the number of the spines and soft rays of the dosal and anal fins, the present authors think it better to give a new scientific name to the nomeid. fish from Japan to which Dr. KAMOHARA gave a Japanese name “Sudji-hanabira-uwo”. This species has teeth on the vomer, palatines and tongue suggesting its close relation with Cubices and Parapsenes, but lacks the mucous pores on the body which are remarkable in some stromateoid fishes. The authors wish to express their sincere thanks to Dr. Fujio UTINOUMI (Seto Marine Biological Station), Prof. GUIBE. (Museum National d'Histoire Naturelle, Paris), Dr. BLANC (the same museum as above), Mr. D. AOKI (Manazuru Fish Market) and Mr. M. WATANABE (Izumi Junior High_ School, Atami City) for their kindness and cocperation.
Part 17 of the article contains 7 new additions to the list of the Fishes of Suruga Bay, Japan, bringing up the total number of the fish fauna in this bay, including of the freshwater species found near the coast, to 895. The interesting additions are Diaphus tanakai (formerly known only from the southern coast of Kyushu, Japan), Lepidocybium flavo-brunneum, Chrionema chryseres, Squaliolus laticaudus, etc.
The present paper, the third of the series of the pelagic fish eggs from Japanese waters, contains the figures and descriptions of the egg and larval development of 35 species, and the matured ovarian eggs of 4 species belonging to the suborder Percina. These eggs, so far as known from Japanese waters, are spherical in shape, measuring 0.6-1.6 mm in diameter, with a single oil globule measuring 0.1-0.5 mm in diameter. The egg membrane is smooth, without any conspicuous structure, the perivitelline space narrow. The yolk is segmented in Oplegnathus fasciatus (TEMMINCK et SCHLEGEL), O. punctatus (TEMMINCK et SCHLEGEL) ?, Mullidae Nos. 1 and 2, Acropoma japonicum GÜNTER, Sillago japonica TEMMINCK et SCHLEGEL, S. parvisquamis GILL ?, Gerres japonicus BLEEKER and Parapristipoma trilineatum (THUNBERG), but not segmented in Acanthocepola krusensterni (TEMMINCK et SCHLEGEL), Lateolabrax japonicus (CUVIER), Epinephelus fario (THUNBERG), Pseudosciaena crocea (RICHARDSON), P. manchurica (JORDAN et THOMPSON), Collichthys lucidus (RICHARDSON), C. niveatus JORDAN et STARKS, Argyrosomus japonicus (TEMMINCK et SCHLEGEL), A. argentatus (HOUTTUYN), Nibea sp., Girella punctata GRAY, Girella sp., Evynnis japonica TANAKA, Rhabdosargus sarba (FORSKÅL), Mylio macrocephalus (BASILEWSKY), M. latus (HOUT-TUYN), Chrysophrys major TEMMINCK et SCHLEGEL, Sparidae-type Nos. 1-7, Lethrinus nematacanthus BLEEKER, Nemipterus virgatus (HOUTTUYN), Taius tumifrons (TEMMINCK et SCHLEGEL) Leptoscolopsis nagasakiensis TANAKA, Goniistius sp.type 1 and 2. In most species the melanophores and xanthophores appear on the embryonal body, yolk, oil globule and rarely on the marginal fin during the egg development, but in some species lack the both or one of these pigment-cells on the yolk or oil globule. In Mullidae Nos. 1 and 2 only the melanophores appear, and in G. punctata and G. sp.no pigment-cell appears in the egg. The oil globule of the newly hatched larva is situated in the anterior part of the yolk in O. fasciatus, O. punctatus?, Mullidae Nos. 1 and 2, L. japonicus, G. japo-nicus, R. sarba, L. nematacanthus, Goniistius sp.type 1 and 2, and it is situated in the posterior part in P. crocea, P. manchurica, C. lucidus, C. niveatus, A. argentatus, N. sp., S. japonica, G. punctata, G. sp., E. japonica, M. macrocephalus, M. latus, C. major, Sparidae-type Nos. 1-7, N. virgatus, T. tumifrons, P. trilineatum and L. nagasakiensis. The species grouped under the name of “Sparidae-type” are not only similar to each other in their developmental course but also closely resembling to known species belonging to the family Sparidae. They are discriminated from other systematic groups by the following characteristics: (1) Newly hatched larvae have a rather large xanthophore immediately before and behind the eye, behind the ear vesicle and on the middle of the tail. In some species small pigment spots, other than above described ones, scatter all over the body, (2) during the course of the egg development no pigment appears on the yolk surface (rarely a few xanthophores appear on the surrounding area of the oil globule) and (3) the myotome number of the hatched larva is 25-28.
