NO. 2011. FISHES FROM JAPAN— JORDAN AND THOMPSON. 67 



The flexible, projected tip of the maxillary places it in the extreme 

 of the genus, approaching Oinsthognatlius. From other species of 

 the genus, it is distinguished by the minute teeth, the outer scarcely 

 enlarged, not canine. Other characters are the very porous skin of 

 the head and the naked breast and shoulders. These characters sep- 

 arate it from the fifteen other species of the genus Gnathypops in 

 Asiatic, Australian, and East Indian waters as far as can be judged 

 by descriptions and figures. All the American species have the teeth 

 more enlarged. 



Family CHAMPSODONTID^. 



CHAMPSODON VORAX GUnther. 



A Specimen 94 mm. long differs from the plate given by Giinther 

 m the ''Shore Fishes" of the Challenger Expedition, in having the 

 anterior rays of the second dorsal elevated, the second ray being half 

 the length of the head instead of a third. Other specimens in the 

 Stanford University Collection from Wakanoura show intergrada- 

 tions, however, and we do not venture to separate the common 

 Japanese species from the East Indian Champsodon vorax. 



Family SCORP^NID^. 



PTEROIS LUNULATA Temminck and Schlegel. 



One small specimen, typical. 



Family HOPLICHTHYID^. 



HOPLICHTHYS LANGSDORFII Cuvier and Valenciennes. 



A Specimen showing the typical two-spined body scutes as in the 

 plate given by Cuvier and Valenciennes, beside numerous other char-

 H. gilberti, and H. regani.
