VOL. xxxin. 



Color in spirits grayish, with dark specks and small clusters of 

 punctulations ; back with 4 dusky cross bands; belly whitish; spinous 

 dorsal dusky in the membranes posteriorly, the tips of the rays 

 whitish; rays of soft dorsal specked at broad intervals with dusky; 

 caudal rays specked outwardly, the base of the fin with a diffuse blotch 

 of dusky; latter third of anal with a subedging of dusky, in the mem- 

 brane; pectorals specked in both rays and membranes. 



(Named for Dr. Charles Henry Gilbert, of Stanford University.) 

 This species differs from Hoplichthys langsdorfii in its greater number 

 of anal rays, shorter pectoral appendages, shorter ventrals, longer nose, 

 less lobed and less spinous lateral facial profile. The figure of Hop- 

 licMJiys langsdorfii in Temminck and Schlegel, which is evidently inac- 

 curate in several particulars, whether it be intended to represent H. 

 langsdorfii or the present species, may with some reservation be re- 

 ferred to H. gilherti, with which it agrees in the short pectoral append- 

 ages and in the larger number of anal rays. The fact that those

authors say in their description that their specimen had 17 or 18 anal 

 rays would alone seem to leave little question that they were at least 

 not the same as Hoplichthys langsdorfii Cuvier and Valenciennes. 



Hoplichthys citrinus Gilbert, recently described from Hawaii, is 

 close to the present species, differing from it chiefly in the more marked 

 lobing and spination of the lateral facial edges, and in the yet shorter 

 pectoral appendages, the longest of which is contained 2.2 in head 

 (female) , 



Known and here described from 9 specimens, 3 to 6.50 inches long, 

 taken by the United States Bureau of Fisheries steamer Albatross in 

 75 to 100 fathoms off Ose Point, Suruga Bay, in 1900, and one speci- 

 men 5.25 inches long from station 5070, Suruga Bay, in 1906, Alba- 

 tross expedition of 1906, in 108 fathoms. 



Type.— The last-named, Cat. No. 51271 U.S.N.M., is the type of the 

 species. The figure is taken from it.
