284 DEEP-SEA FISHES OF THE ATLANTIC BASIN. 



Up to the time of the visit of the U. S. Fish Commission to Salem in 1877 this species 

 had been very rarely taken sonth of Greenland, and that mainly from the stomaehs of cod, 

 haddock, halibut, and other fishes. Several specimens were dredged by the Commission at 

 Portland and P^astport, Me. Many specimens were taken in Massachusetts Bay, often a 

 dozen coming- up in a single haul of the trawl. 



In 1874 theheadof an individual of this species was dredged ui) on the ''Pecten Ground," 

 off Watch Hill, It. I. This was the first instance of its caitture south of Cape Cod. 



It was subsequently taken at the f(»llowing Albatross stations: 2502, in 44° 19' N. lat., 

 GOO 39' 15" W. Ion., at a depth of 54 fathoms; 2491, in 45o 24' 30" N. lat., 58° 35' 15" W. 

 Ion., at a depth of 59 tixthoms; 2522, in 42° 20' N. lat., (ioo 07' 30" W. Ion., at a depth of 104 

 fathoms; and 2450, in 40° 45' N. lat., 50° 02' 30" W. Ion., at a depth of 44 fath(mis. 



A specimen, doubtfully assigned to A. Olrilci, was taken at station 2450, in 40° 45' N. 

 lat., 50O 02' 30" W. Ion., at a depth of 44 fathoms.

Latilida; Ciihi,, Arr. Fain. Fishes, 1872, 9 (No. 97). — Jordan and OiLiiEUT, Bull, xvi, U. S. Nat. Mus., 623. 



Acauthopterygians with body more or less elongate, compressed. Scales small, ctenoid. 

 Lateial line present, complete. Head subconical, the profile usually convex; suborbital 

 without bony stay ; cranial bones not cavernous; opercular bones armed or not. Mouth 

 moderate, terminal. Teeth rather strong. Premaxillary (usually) with posterior canine, 

 protractile; maxillary without supplemental bone, not slipping under edge of pre()rl)ital. 

 Gill-membranes often adherent to the isthmus. Dorsal fin long and low, usually continu- 

 ous, the spinous portion much shorter than the soft. Anal fin elongate, witli spines few 

 and feeble. Caudal fin forked; tail dii)hycercal. Ventrals thoracic or subjugular, perfect. 

 Pectoral fins normal. Vertebrae, 35-50. 



LOPHOLATILUS, Goode and Bean. 

 Lopholatilus, Goode and Bean, Proc. U. S. Nat. Mus., 1879, 205 (type, LophulniUtis clianurlcojitlccpx, 0. & li.). 



Dorsal and anal rays few in number. A large adipose appendage on the nape and a 

 fleshy prolongation upon each side of the labial fold, extending backward beyond the angle of 

 the mouth.

A Lopholatilus having a stout, somewhat compressed body, with its lieight contained 

 3J times in its length (without caudal), and the length of its head 3 times. 



Maxillary reaching anterior margin of orbit; opercle and ])reop('rcle scaly, the latter 

 finely denticulate; upper jaw with an outer series of stronger teetli, beliiiid wiiich is a band 

 of villifbrm teeth; lower jaw with a few large canines and an inner series of small ((uiical 

 teeth; vomer and palatines toothless. 



Radial formula: D. vil, 15; A. ii, 13; scales 8-93-30. 



iMuiled description. — The greatest height of the body (.306), which is at the ventrals, 

 is contained about 3;^ times in the length to the origin of tlie middle caudal rays, and 4 times 

 in the extreme length. Its greatest width (.144) equals tln^ length of the caudal peduncle 

 (.144) ; this latter being measured from the end of tlie soft dorsal to tli(> origin of tlie middle 

 caudal rays. The least heiglit of the tail (.0807) is contained 4 times in tlie distance of the 

 spinous dorsal from the snout. 



The greatest length of the head (.33) is contained 3 times in tlie length to fhe origin of 

 tlie middle caudal rays. Its gicatest width (.105) is sliglitly mor(^ than twice the width of 

 the interorbital area (.08). The length of the snout (.122) is contained twice in the length
