150 - DEEP-SEA FISHES OF THE ATLANTIC BASIN. 



the same as in t ho case of those upon the head. Height of dorsal aud anal fins about equal 

 to half the height of body. 



Color, apparently, brownish; peritoneum black. 



The tyi^es of F. procera were two fishes obtained at station 325, N.lat. 33° 35' 20", W.lon. 

 Tfio, ata(lei)th of 017 fathoms. Another mutilated specimen, about 190 millimeters long, 

 w\is taken at station 327. This species is in many respects closely allied to the NcttHxtoma 

 melanurim of the Mediterranean, but appears to differ ft'om it in the greater length of the tail, 

 the much smaller teeth, and in the presence of a filamentous nasal tip. 



VENEFICA PROBOSCIDEA, (Vaillant), Jordan ami Davis 

 Nettastoma prohoscideum, Vaillaxt, Exp. Sci., Travailleur et Talisman, Poissons, 1888, 89, pi. vii, fig. 3. 



A KettaHtoma, with upper Jaw projecting quite beyond the lower, and prolonged in a 

 proboscis-like tip half as long as the upper jaw and 5 times the diameter of the eye, with 

 mouth-cleft extending far behind the orbit. Teeth small, in cardiform bands on jaws and 

 palatines. Tail one-half to three-fifths the length of body (head included). Diameter of the 

 eye one-twentieth the length of the head. 



This, described from a single specimen obtained off Morocco, at 2,200 meters, is a 

 small-eyed form, with fine teeth and a nasal extension. The length of the nasal tip is, 

 essentially, an unreliable character, and the proportion of tail to body may prove to be sub- 

 ject to considerable individual variation. 



CHLOPSIS, Rafinesque. 



Chlopsia. Rafinesque, Ind. Itt. Siiili.aua, 1810, 58. — Jordan ami Davis, Eep. U. S. F. C, 1888, 650. 

 Saurenchely8, Peters, Berliner Monatsberichte, 1864, 397. 



A genus closely allied to Nettastoma, having the nostrils lateral, the posterior one 

 slit-like and placed near the eye. Body scaleless. Snout much produced. Jaws, vomer, 

 and palatine bones with several series of small, pointed teeth, those along the median line 

 of the vomer being somewhat the larger. Vertical fins well developed ; pectorals none. 

 K^ostrils lateral, the anterior near to the end of the snout, the posterior in front of the 

 eye. Air bladder aud pyloric appendages absent. (Peters.) 



Two species are known, one, C. equatorialis, Gilbert, taken by the Albatross off the 

 coast of Ecuador, in 401 fathoms, the other, C. bicolor. 



CHLOPSIS BICOLOR, Rafinesque. 



CMopnis hii-olor, Rafinesque, loc. eit., 59. — Jordan and Davis, loc eit. 

 Saurenckelys cancrhora. Peters, loc. eit. — Gunther, Cat. Fish. Brit. Mu.s., viii, 48. 



Tail tapering into a point. Gill opening one-fifth more distant from vent than from the 

 end of the snout. Diameter of eye one-third of the length of the snout. Length of head 

 two-fifths of total length. Dorsal fin commencing immediately behind the gill opening. 

 Upper jaw the longer. Vertical fins with a black margin posteriorly. Peritoneum silvery. 

 (Peters.) 



The unique specimen from which the above characters were taken was found by Dr. 

 Peters, in the Berlin Museum in a jar of fishes, chiefly from India. A crab found in the 

 stomach led Dr. Peters to believe that the fish had been misplaced, and actually had come 

 fi'om the Mediterranean or the Atlantic. Its resemblance to Nettastoma and the fact that 

 it is not known in any shallow-water fauna lead us to believe that it is probably a deep- 

 water form.
