middle of the eye. Tlie greatest depth is about equal to tlie leugtli of 

 the head. The pectoral reaches to above the anal origin. The dorsal 

 begius over the axil of the pectoral. D. 52 ; A. 47. Color aloug back 

 of some examples light brown, elsewhere uniformly pale. 



Icelus scutiger, uew species. 



Three individuals were collected, August 9, 1888, at station 2853, in 

 north latitude 5Qo^ west longitude 154o 20', depth la'J fathoms, off Trinity 

 Islands. 



D. IX, 19; A. 18 ; V. I, 3 ; lateral line 41. 



The eye is twice as long as the snout and two-fifths as long as the 

 head. The head is one-third as long as the total without caudal. The 

 maxilla extends to below the middle of the eye, and is broadly ex- 

 panded behind. The iuterorbital space is extremely narrow, less than 

 one fourth the length of the eye. The depth equals one-fifth of the 

 total without caudal. The pectoral extends to above the sixth ray of 

 the anal. The pre-operculum has a weak, simple spine hooked upward, 

 and three v;eak ones pointing backward and downward. Teeth on 

 vomer and palate. 



The head has minute spiny scales most abundant on the upper half. 

 All of the back above the lateral line is densely covered with small 

 spiny scales. The lateral line is made up of raised tubes. There are 

 a few rough scales under the lateral line in the second half of the body. 



The branch iostegal membranes are broadly united and well freed from 

 the isthmus. Slit behind fourth gill obsolete. 



Tiie spinous dorsal is very high, its longest spine two thirds as long 

 as the head. About four large, dark blotches across the back and sev- 

 eral smaller ones between them. 



The type is 3^ inches long. 



Icelus euryops, new si)ecies. 



Three examples were obtained August 0, 1888, off Trinity Islands, at 

 station 2853, with Icelus scutiger. 



D. IX, 23 ; A. 18 ; V. 1, 3 ; lateral line, 43. 



The eye is about twice as long as the snout and two-fifths as long as 

 the head. The head is one-third of the total length to base of caudal. 

 The maxilla scarcely extends to below the middle of the eye. The iu- 

 terorbital space is about one-fourth length of eye. The depth of body 

 is contained 5% times in total without caudal. The pectoral extends to 

 above the second ray of anal. The preopercle is armed as in Icelus scu- 

 tiger. Vomer and palate well toothed. 



The head is scaled as in I. scutiger. The lateral line is composed of 

 raised tubes. A single series of spiny scales on the back aloug the 

 bases of the dorsals. Branchiostegal membranes broadly united, free 

 from the isthmus. Slit behind last gill obsolete.
