42 NEW ALASKAN FISHES BEAN. 



The spinous dorsal is low, its longest spine less than one-third 

 length of head. Four dark bands across the back, the first over the 

 end of tho spinous dorsal, two on the soft dorsal and one at the base of 

 the caudal. General color, light brown. 



Dasycottus, new genus. 



Related to Cottuiiculus, which it resembles in shape. Head large, 

 with large bony tubercles and numerous filaments. Mouth wide; 

 jaws equal, or lower jaw slightly projecting. Teeth minute, in villiform 

 bauds in the jaws. Vomerines in two patches, separated by an inter- 

 space. Palate toothless. Preopercle with two spines at its angle and 

 two rudimentary ones on each edge of its lower limb. Gills 3^, no slit 

 behind the last. Gill-rakers short, tubercular, in moderate number. 

 Gill-membranes free from the isthmus. Pseudobranchijie present. Skin 

 smooth, exce[)t on nape and along dorsal base, where it bears a few 

 small, bony tubercles. Spinous dorsal well developed and separated 

 from the soft dorsal by a deep notch. Pectorals moderately long, their 

 ray^iprocurrent below. Ventrals with a spine and three rays. Caudal 

 rounded. 



Dasycottus setiger, new species. 



Four individuals were trawled August 10, 1888, at station 2855, north 

 latitude 57°, west longitude 153° 18', at a depth of G9 fathoms, off 

 Sitkalidak Island. 



D. IX, 15; A. 13; V. I, 3; pores in lateral line, 11 or 12. 



The depth equals about two thirds length of head, which is nearly 

 one-half of total length of base of caudal. The eye is nearly equal to 

 the snout and is two-ninths of the length of head. The maxilla is ex- 

 panded behind; its length equals that of the snout and eye combined; 

 it extends to a little behind the middle of the eye. 



The i)ectoral extends to above the anal origin. The ventral is one- 

 half as long as postorbital part of head. The longest dorsal spine is 

 about equal to the eye in length. Spinous dorsal with two dusky bands 

 extending down on the sides; soft dorsal with two bands. A similar 

 one at caudal base and three narrow bands on second half of caudal. 

 Pectoral indistinctly banded. Head speckled with brown dots. 



Malacocottus, new genus. 



Shape similar to that of Cottimculus. Head large ; body tapering 

 rapidly to the slender tail; mouth terminal; jaws subequal. Minute 

 villiform teeth in broad bands on maxilla and mandible; vomer and 

 palate toothless. Preoperculum armed with short, stout, simple spines. 

 Bones of the skull thin. Gills 3i ; no slit behind the last. Gill-openings 

 wide, the membranes broadly attached to the isthmus. Gill-rakers tu- 

 bercular, in moderate number. Si)inous dorsal low, separated by a deep
