under the end of the dorsal, or nearly so. Pseudobranchias present. Gill openings very 

 wide, separate,

 TiiER, Challenger Report, xxii, 34. — Jokdan, Cat. Fish. N. Amer., 1885, 75. 



Height of the body two-sevenths of its length to base of caudal rays; its width about 

 one-half its height. Scales as large as the pnxiil, witli concentric stria;, about twenty-four 

 in the lateral line and about ten in the transverse series. 



Head about two-flfths of standard length, somewhat resembling in appearance that of 

 Aleponphdl UH liniidti. The eye is large, circular, located normally. The length of the 

 upper jaw is three-sevenths that of the head; that of the lower jaw about one-half. The 

 end of the maxillary is nearly in the perpendicular from the posterior limb of the pupil. 

 The length of the snout is about equal to the least diameter of the eye. The distance from 

 the limb of the preoperculum to the end of the opercular flap is equal to that from the tip 

 of the snout to the posterior margin of the orbit. Teeth as described in generic diagnosis. 

 Dorsal fin inserted midway between tip of snout and origin of middle caudal rays. The fin 

 is mutilated and its outline can not be determined; it is composed of 7 or 8 spines and (J 

 soft rays, and the length of its base is nearly equal to the height of the body at its insertion. 



The anal fin is inserted in the perpendicular from the base of the eighth dorsal ray. It 

 is composed of nine rays, and the length of its base is half that of the dorsal base. 



The pectoral is inserted far below the axis of the body, and with a single scale between 

 its axil and the branchial opening. Its length is twice the distance of its insertion from snout. 



The ventral is minute (apparently) and is inserted in advance of the pectoral; it has 

 about 7 or 8 rays. 



The caudal is mutilated, but seems to be composed of 15 rays.

Two specimens of this species were secured by the Blale; one from station cccxxvin, 

 in 340 28' 25" N. lat., 75° 22' 50" W. Ion., at a depth of 1,632 fathoms; the other from an 

 unknown locality.
