 Carrprootus majnr, (Iau.man, Discoboli, 18112. 



Diameter of eye contained nearly 3 times in snout or interorbital space. Posterior 

 nostril not tubular. Pseudobranchise reduced to 2 lamellae. Vertical fins continuous; anal 



beginning below tenth dorsal ray. Ventral disk longer than broad, half length of head. 

 Skin thin, loose. 



Radial formula: I). 42; A. 34; C. 12; P. 34. 



Color, yellowish, mottled with brownish. 



Liitken states that he received a great number of specimens of this Arctic species from 

 the Kara Sea, where they were obtained at depths varying from 40 to 106 lath s. 



This form is provisionally placed in Careproctus, but we are quite prepared to believe 

 that Gill's Aetinochir is a valid genus. The fish has a close external resemblance to the 

 species of Liparis: 



CAREPROCTUS MICROPUS,(Gunther), Garman. 



Liparis micropus, GOnther, Challenger Report, xxn, 1887, 66, pi. xn, fig. B. 

 Careproctus micropus, Garman, Discoboli, 1892, 72. 



Head large and thick, about one-fourth of the total length, the caudal included. The 

 interorbital space equals in length the postorbital portion of the head. Eye entirely in the 

 anterior half of the head and one-fifth of its length. Nostrils not tubular. Cleft of the 

 mouth not extending to the front margin of the eye. Teeth simple, unicuspid. 



Vertical fins continuous, caudal very narrow and pointed. The origin of the anal is 

 opposite to the eighth dorsal ray. Form of the pectoral typical, the foremost rays being 

 opposite to the anterior margin of the ventral disc. Ventral disc circular, small, one-fourth 

 of the length of the head, situated immediately behind the level of the eye. Vent very 

 close to ventral disc. Color light grayish or purplish. (Gunther.) 



Two specimens, 2 and 34 inches long, were obtained by the Knight Errant at station 9, 

 from a depth of 608 fathoms; and also a single individual, 3i inches long, at station 8, in 

 540 fathoms. 



AMITRA, Goode. 



Amitra, Goode, Proc. II. S. N. M., in, sig. M0, 478, Feb. Iti, 1881.— Jordan and Gilbert, Bull, xvi, U. S. 



N. M., 739. 

 Monomitra, Goode, Proc. U. S. N. M., vt, 478-9. (July, 1883.) 



Liparids with small head and an elongate, attenuate body, covered with thick, lax, 

 slimy skin. Ventral disk absent. Opercular stay present. Pseudobranchise present. 

 Gills ,'U, without slit behind last. Gill-openings closed below, restricted to small slits 

 tinder the very small operculum. Operculum very small, Strap-shaped. Lowerjaw included 

 within the upper. Teeth weak, paved. First five rays of the dorsal non-articulate, the 

 ol hers grading gradually into the tlexible rays. Pectoral simple, with low est rays prolonged.
