 this or a related species (Cat. No. 2G179, U. S. N. M.) were obtained by the Fish Hawk from 

 station 894, in 39° 53' N. lat., 700 ag/ 30// yy. Ion., at a depth of 365 fathoms, bnt they ar(>

 and four examples (Cat. No. 35562, U. S. N. M.) from station 2212, in 39o 59' 30" N. lat., 70^

Head short and globular; equal in length to the depth of the body, and is to total 

 length as 1 to 5.^ ; eyes (orbita') large, their longitudinal diameter being to the length of the 

 head as 1 to 3|, and to width of intcrorbital space about as 1 to Ig; the dorsal and anal 

 fins covering two-thirds of the caudal ; snout short, bnt slightly exceeding the diameter of 

 the orbit; the upper and lower divisions of the pectorals are sepaiated by a space furnished 

 with 3 to 4 rudimentary rays. (Concerning the eyes, the ventral disk, and the position of 

 the vent nothing is known. — Collett.) 



Eadial formula: D. 59; A. 51; P. 13 | 3 (4) | 3; C. 8. 



Color, brownish-black. 



Length of body in the specimen examined (female) 208 millimeters. (CoUfft.) 



Collett's type was obtained 108 kilometers west of Bear Ishmd, in ().58 fathoms. The 

 Knight Errant collected it at station 8, 1882, in 640 fathoms. 



PARALIPARIS COPEI, Goode and I?e.\n, n. s. (Figure 253.) 



This species lias nearly the same number of rays in the dorsal and anal as are recorded 

 in P. bnthyhiH.% but the pectoral has 17 rays in the upper portion and 3 in the lower. The 

 jaws are .shorter than in P. hatht/bins; the fnrm is more elongate and the coloration is strik- 

 ingly different, our species having the anterior half of the body pale, almost whitish, while 

 the snout, chin, and anal origin are black. 



The standard length, which is tlie total without caudal, of the specimen examined is 

 167 millimeters. The greatest height of tlie body (25 millimeters) is sliglitly greater than 

 the length of the head, which is contained (J^ times in the standard length. 



The snout is broad, obtuse, its length (7 millimeters) contained 3i times in that of the 

 head. The length of the eye eipials that of the snout. The intcrorbital width (II milli- 

 meters) equals the length of the postorbital part of the head. The nostril is about midway 

 between the eye and the tip of the snout, iu a very short tube. Five large mucous pores 

 on each side of the snout, 3 smaller ones on the cheek under the eye and (! on the man- 

 dible and edge of the opercular bones. The teeth are minute, villiform, and in two series. 

 The gill-opening is a very small slit, edged with black at the upper angle of the i)ectoral. 

 The origin of the dorsal is distant from t lie snout 36 millimeters, or U times the length of
