40 NEW ALASKAN FISHES BEAN. 



Dorsal and anal finely scaled almost to their margins. The upper 

 lateral line begins in front of the upper axil of pectoral and extends to

The lower line begins under about the seventeenth ray of the dorsal 

 and continues to the root of the caudal. 



Color, brown; margins of dorsal and anal bluish.

 interorbital space narrow. Mouth small, lower jaw slightly included; 

 teeth on vomer and palate; narrow bands of teeth in jaws, the outer 

 series enlarged. Gill openings slightly prolonged forward below, nar- 

 rowly attached to the isthmus anteriorly. Dorsal composed of many 

 sharp, flexible spines, diminished in length anteriorly. Caudal long, 

 pointed. Anal with three spines and many rays. Pectorals large, the

Poroclinus rothrocki, uew species. 



A single individual, 7 inches long, was taken August 4, 1888, at sta- 

 tion 2852, north latitude 55° 15', west longitude 159° 37', at a depth of 

 58 fathoms, between Nagai and Big Koniushi Islands. 



B. VI; D. LXI; A. Ill, 41; V. I, 3. 



The eye is a little longer than the snout, and about one-fourth 

 length of head. The maxilla extends a little beyond front of eye. The 

 length of the head is contained 6i times in total without caudal; the 

 depth 11 times. The dorsal origin is distant from tip of snout a space 

 equal to length of head. The pectoral is about two-thirds as long as 

 the head, and is distant from the vent a space equal to its own length. 

 The ventral equals two-thirds depth of body. The caudal is nearly as 

 long as the head. 



Ten narrow pale bands on the sides extending downward about to 

 the median line. Caudal with a double crescent-shaped pale marking. 

 General color, light yellowish brown. Dedicated to Dr. J. T. Roth- 

 rock, professor of botany, University of Pennsylvania. 



Careproctiis spectrum, new species. 



Twenty-six specimens were obtained, July 31, 1888, at station 2848, 

 in north latitude 55^10', west longitude 160° 18', 110 fathoms, between 

 Unga and Nagai Islands. 



The example figured and diagnosed is 3i% inches long. The ven- 

 tral disk is small, two-thirds as long as the eye, which is one- third as 

 long as the head. The head is one fourth of the total length to base of 

 caudal. The mouth is large, the maxilla extending to about below the
