from Formosa is a new species. Bh-ekeria mitsukurii, which differs 

 from the other species of Eleekeria in the presence of ventral fins. 

 These are very small, jugular in position, and composed of a slender 

 spine and three rays. The scales in this species are very small, 

 about 115 in a longitudinal series, this count being, by a slip of the 



conclusively that the Ammodytidae are not related to the Percesoces, 

 are not derived from Cobitopsis or Crossognathus, and that their 

 real place is with the ophidioid fishes and Fierasfer. The Formosan 

 species is the type of a distinct genus, characterized by the presence 

 of ventral fins. For this, the name Embolichthys Jordan and Ever- 

 mann (V^oAos, a hint) has been elsewhere proposed. I). S. J. 



Fishes of Japan. — The series of monographic reviews of the 

 fishes of Japanese waters is continued by Jordan and Fowler, and 

 Jordan and Snyder, in the Proceedings of the United States National 

 Museum. (Vol. XXV). There is included: 1. A " Review of the 

 Salmonoid Fishes," the Salmonidai, (10 species); the Argentinida;. 

 (4 species), and the Salangidae, (2 species). Four salmon 

 (Oncorhynchus mason, O. keta, O. kisutch, and O. nerka) are found 

 in Japan, one of these, O. mason, not yet known from any other 

 region. One salmon trout, Salmo perryi, is found in all streams of 

 middle and northern Japan. A large pikelike trout, Hucho blackistoni, 

 common in northern Japan, finds its only analogue in the huchen 

 {Hucho hucho) on the Danube. There are three charrs in Japan, — 

 one common, Salve I in us pluvius ; the other two, S. kundsha and S. 

 malma, confined to the northern islands. The ayu, Plecoghnsus 

 a/tive/is, is found in all rivers. It is one of the finest food fishes in 

 the world, — a sort of dwarf salmon with peculiar dentition. 



Of the smelt, Osmerus dentex, Mesopus o/idus, and Mesopus 

 japonicus are described, besides a new species Argentina kagoshimce. 

 Besides the diminutive and fragile Japanese ice-fish, Salanx microdon, 

 a second species, Salanx ariakensis is described from manuscripts 

 of Dr. Kishinouye. 



The part of this paper of popular interest in Japan is condensed 

 in an article, " The Salmon and Trout of Japan," in the " Aimoiationes 

 zoologicce Japonenses," published by the Imperial University of 

 Tokyo. 



2. A " Review of the Labroid Fishes and Related Forms " includes 

 45 species: of Pomacentridai, 11 ; Labridte, 31 ; and Scarida? (3). 

 The new species are Stethojulis psacas, S. teriua, S. trossula, and
