NO. 1581. FISHES OF JAPAN— JORDAN AND RICHARDSON. 647 



figured as 17, but stated by Cuvier to be 16, is likewise 16 in our 

 specimen, and was found by Doctor Gtinther to be 16 in several 

 specimens from Cliina and Japan. The larger number of anal rays 

 in Sclilegel's specimens, stated in the description to be 17 or 18, and 

 the much lower spinous dorsal and shorter pectoral appendages, as 

 shown in the figure, make it ahnost certain that it represents a species 

 distinct from H. langsdorjii Cuvier and Valenciennes, and probably 

 identical with Hoidichthys gilherti, next described. 



Here described from a single specimen 5^ inches long, obtained at 

 Kagoshima and presented to Stanford University by Professor 

 Mitsukuri. 



(Named lor M. Langsdorf, who brought the first specimens from 

 Japan.)

 p. 593 (Suruga Bay, off Ose Point). 



Habitat. — Seas of Japan, north to Suruga Bay, in deep water. 



Head 3.4 in length to base of caudal; depth 13; depth of head 3.6 

 in its length; width of head 1.3; eye 3.6; interorbital space 4 m eye; 

 maxillary 3.2 in head; nose 3.3, longer than eye; D. VI-15; A. 17; 

 scutes 27. 



Back and sides with an incomplete coat of mail formed of two rows 

 of keeled scutes, as m Hoplichthys langsdorjii; each keel ending in a 

 strong spine, below which is a small concealed one, as in that species; 

 top of head with low serrated ridges; lateral facial edge less spinous 

 than in Hoplichthys langsdorjii, and with much less distinct lobes, the 

 notch under pupil scarcely noticeable, being nearly continuous with 

 the weakly serrated edge in front of and immediately behind it; angle 

 of preoperculum with 2 long curved spines, as in Hoplichthys langs- 

 dorjii; spines on under side of head rather weaker than in Hoplichthys 

 langsdorjii; villiform teeth in bands on jaws, vomer, and palatines; 

 tip of tongue slightly emarginate. 



Spinous dorsal (m female) low, its longest spine 3 in head, the 

 depressed fin falling well short of the second fin; soft dorsal long and 

 low, without filamentous rays, its longest ray (anterior) 2.2 in head; 

 soft dorsal and anal about opposite; pectoral 1.4 in head, the 3 de- 

 tached pectoral rays much shorter than in Hoplichthys langsdorjii, 

 the longest 1.7 in head, failing of reaching tip of pectoral by a distance 

 nearly equal to diameter of eye; ventrals rather short 2.25 in head; 

 caudal slightly emarginate.
