notch from the soft dorsal. Pectorals procurreut iu front. Ventrals 

 small. Caudal rounded. Vent distant from the anal origin. Head and 

 body naked. Lateral line consisting of a series of large pores. 



Malacocottus zonurus, new species. 



D. IX, 14; A. 11; V. I, 3; pores in lateral line, about 14. 



The eye is about equal to the snout in length and is two-sevenths as 

 long as the head. Interorbital space less than one-half length of eye. 

 The maxilla extends to below the middle of the eye. The pectoral 

 reaches to a vertical through the anal origin, or a little beyond. The 

 ventral is scarcely as long as the eye. The depth equals length of head 

 without snout. Spinous dorsal low; its base one-half as long as the 

 head ; its longest spine two-thirds as long as the eye. Tbe beginning 

 of the dorsal is immediately above the upper angle of the gill-opening. 

 The least height of the tail is scarcely two-thirds length of eye. Four 

 spines on the preopercle, the largest less than one-half as long as the 

 eye and with a supplementary spine at its base. 



A dark-brown saddle-shaped band over the end of the spinous dor- 

 sal and two on the soft dorsal. A brown band at the base of the tail 

 and three on the caudal. Pectoral with several indistinct dark bands 

 intermingled with pale areas. Tips of pectoral in its lower half ex- 

 serted, milky white. 



Seven examples were taken August 9, 1888, at station 2853, iu north- 

 latitude 5GO, west longitude lol^, at a depth of 159 fathoms, off Trin- 

 ity Islands. The type of the description and figure is -i'^ inches long. 



Hemitripterus marmoratus, uew species. 



Two small examples, each about 2^ inches long, were trawled at a 

 depth of G9 fathoms August 10, 1888, at station 2855, off Sitkalidak 

 Island, north latitude 57°, west longitude 153° 18'. 



D. XIV, 12 ; A. 13 ; V. I, 3 ; 44 tubes in lateral line. 



The eye is about as long as the snout and one-quarter as long as the 

 head, which is three-eighths of the total without caudal. The depth is 

 three-elevenths of the total witiiout caudal. The pectoral reaches to 

 the vertical through the anal origin. The ventral is scarcely longer 

 than the eye. The gill menibraue is free from the isthmus. The max- 

 illa reaches beyond the end of the eye. The first dorsal base is as long- 

 as the head without the snout ; the first four species are less elevated 

 and differentiated than is usual in the genus. 



Sides dark gray, intermingled with whitish reticulations. 



Psychrolutes zebra, new species. 



Many individuals were secured July 31, 1888, at station 2818, north 

 latitude 55° 10', west longitude 160° 18', at a depth of 110 fathouis, be- 

 tween C nga and Nagai Islands.
