UESCRIPTIOIV OF A SPECIES OF I^YCODES (I,. PAXII.I.IT.S) OBTAINED 

 BV THE UNITED STATES FISH COMMISSION. 



By O. BROWN OOODi: and TARLETOTV H. B£A1V. 



A single specimen of an apparently undescribed species of Lycodes 

 was obtained by Capt. Joseph W. Collins and tbc crew of the schooner 

 Marion of Gloucester, from the gully between Le Have and Sable Island 

 Banks, in latitude 42° 48' N., longitude 63° 07' W., and presented to the 

 United States Fish Commission for the National Museum. The speci- 

 men, which is 14| inches in length, is in a dilapidated condition, and was 

 apparently taken from the stomach of a fish, probably a halibut. Fish- 

 ing in this locality is carried on exclusively with trawls or long-lines at 

 a depth of 1,200 to 2,400 feet. 



The form of Lycodes imxillus is rounder and more terete than that of 

 any other described species. It is also easily distinguished by its very 

 short head, by the peculiar curvature of the strong jaw, and by the 

 enormous development of the muscles of the cheek. In the small num- 

 ber of pectoral rays it resembles L.imlaris Sabine,' X. murama Collett, 

 and L. Verrillii Goode & Bean. 



Description. — Body elongate, rounded throughout its entire length; 

 its greatest height (.00) equaling its greatest width (.00) j the height 

 behind the pectorals (.05i) very slightly greater than the width behind 

 the pectorals (.05/j) ; the width at the anus (.04§) exceeding two-thirds 

 of the height (.Oog) at the same place; midAvay from the anus to the tail 

 the width (.03) equals three-fourths of the height (.04J). The greatest 

 height is contained over sixteen times in the total length, and equals 

 slightly more than one-fifth of the distance from the snout to the origin 

 of the anal fin. The width of the body at the anus is about one- third 

 of the length of the head. 



The head much resembles in general form that of the common rattle-
