DEEP-SEA FISHES OF THE ATLANTIC BASIN. 



ter (.07) more than one-fourth of the length of the head, and contained about fourteen times 

 in the length of the body. Width of interorbital area is contained 2J times in length of 

 head. Nostril close to eye. Gill opening a vertical slit, extending upon upper part of root 

 of the pectoral. 



Dorsal is inserted at a distance from snout equal to one-third of length of body. It 

 contains about 48 rays (though to count them is almost impossible). Anal originates at a 

 distance from snout equal to two-fifths of length of body, and in perpendicular from eighth 

 dorsal ray; it contains at least 48 rays. Pectoral moderately broad, with 15 long rays and 

 12 or 13 shorter ones; the long rays are twice as long as the ventral disk and extend nearly 

 or quite to perpendicular from vent. 



Ventral disk slightly longer (.10) than its distance from snout (.09), which precisely 

 equals its width; it has 14 papillae. 



Color is uniform whitish, almost colorless, aud translucent in life. 



This species was taken in the large trawl net by the collecting party on the United 

 States steamer Speedwell, September 24, 1877, off the mouth of Halifax Harbor (station 

 117, 84 miles southeast from Chebucto Head). The depth at which it was found was 52 

 fathoms, the temperature at the bottom 35° F. The bottom was of fine sand aud mud, and 

 in the same haul of the net were taken the following species: Glyptocephalus cynoglossus, 

 Sippoglossoides platessoides, Sebastes mariwus (young), Phycis chuss, Aspidophoroides monop- 

 terygius, Triglops Pingelii, Gentridermichthys uncinatus, and Baia radiata. 



Specimens of this species were also taken by the Albatross from station 2455, in 47° 21' 

 N. lat.; 51° 38' 30" W. Ion., at a depth of SI fathoms. 



The species resembles, in the shape of its head, the Liparis Fabricii of Kroyer, but is 

 easily distinguished by its less elongate body and the greater number of rays in the dorsal 

 and anal fins. When first taken it was colorless, almost translucent, and was covered with 

 a thick tough integument. The preceding description is less complete than would seem de- 

 sirable, owing to the fact that the type specimen (No. 22310, U. S. Nat. Mus. Cat.) was too 

 soft and tender to admit of the requisite manipulation. The specimen, Svbich is 50 milli- 

 meters in total lengt h (caudal included), is a mature female, having in the abdominal cavity 

 many large eggs.
