between base of caudal and origin of spinous dorsal. Color dark or 

 brownish above, with irregular spots or dashes of darker, which do not 

 form definite cross bars; a black streak from eye to tip of snout passing 

 onto lower side of rostral spines ; a dark blotch on expanded limb preoper- 

 cle; a black spot on base of middle pectoral rays, the fin very obscurely 

 marked with dusky; dorsal spines and rays with linear dark markings, 1 

 or 2 black spots near tip of spinous dorsal anteriorly ; under parts includ- 

 ing fins, unmarked. Two specimens from Albatross Station 3653, off' 

 Shana Village, Iturup Island, in 18 fathoms. A young individual from 

 Albatross Station 3646, off Robben Island, 18 fathoms, seems to belong to 

 the same species, but has the snout less produced and the dorsal VIII, 6; 

 anal 8. (We take great pleasure in naming this species in honor of Hon, 

 Charles Sumner Hamlin, late Assistant Secretary of the Treasury, under 

 whose auspices the fur seal investigations of 1896 and 1897 were carried 

 on by the United States Fur Seal Commission.

2411. PODOTHECUS GILBEBTI (Collett). 



Head about 4; depth 7* or 8. D. VIII, 8; A. 9; P. 17; V. I, 2. Body 

 deeper than wide; octagonal to end of dorsal and anal fins, hexagonal on 

 tail. The curved spines of the dorsolateral, superior and inferior lateral 

 ridges strong and sharp as far as base of caudal. Ventral series of plates 

 spinous to origin of anal, uniting behind it to form a single series; dorsal 

 series uniting into 1 behind second dorsal ; about 12 to 15 well developed, 

 radially striated plates without tubercles or spines on breast; a few 

 median plates between ventrolateral series behind vent. Head 4-hedral, 

 tapering, cheeks vertical, orbit large, high up, about equal to the concave 

 interorbital space. Supraocular and occipital ridges high, with crenulate 

 edges, the former ending in a sharp, the latter in a blunt, spine ; suborbi- 

 tal and opercular bones radially striated; suborbital ridge low down on 

 cheek, thin, with crenulate edge and a small sharp spine at its posterior 

 end; preopercle with a high thin keel with serrated edge, ending in a 

 strong blunt spine; rostrum projecting far beyond premaxillaries, with 

 a pair of spines at tip directed forward, another pair, farther apart, curved 

 backward and outward. Maxillary reaching about to front of orbit; 

 lower jaw very short, broad, falling far short of upper. Teeth on lower 

 jaw weak, few and excessively weak on upper jaw, none on voiner or 

 palatines. A group of barbels under tip of snout, another at angle of 

 mouth (specimen with mouth in bad state). Dorsals separated by about 

 3 pairs of plates ; anal begins a little in front of origin of second dorsal ; 

 pectorals about 6 in body, their base nearly 3 in their length ; ventrals 

 (male?) about f as long as pectorals; Lateral line about 35. Color appar- 

 ently brownish or yellowish, with well-defined dark-brown spots on sides 

 of head, back, and sides; the spots largest along sides, some of them as 

 large as the osseous plates, smaller on back; apparently a dark band 

 from front of orbits to tip of snout ; dorsals with dark patches ; a dark
