 Carrproctiis major, Garman, Discoboli, 1892. 



» 



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

 nostril not tubular. Pseudobrauchiae reduced to 2 lamellae. Vertical tins continuous; anal 

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

 yiiin thin, loose. 



Eadial fornnila: D. 42; A. 34; C. 12; P. 34. 



Cohn', 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 46 to 100 fathoms. 



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

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

 species of Liparis. 



CAREPROCTUS MICROPUS,(Gunther), Garman. 



Liparis micropiis, GOnther, Challenger Report, xxii, 1887, 66, pi. xil, fig. B. 

 Careproctus micropus, Garman, Discoboli, 1892, 72. 



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

 interorbital siJace 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 tins 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 

 "Pliosite 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 gTayish or purplish. (Giinther.) 



Two specimens, 2 and 3i inches long, were obtained by the Knight Errant at station 9, 

 from a depth of 008 fathoms; and also a single individual, 3i inches long, at station S, in 

 540 fathoms. 



AMITRA, Goode. 



Amitra, Goode, Proc. U. S. N. M., ill, sig. 30, 478, Feb. 16, 1881.— Joni)\N and Gilbert, Bull, xvi, U. S. 



N. M., 739. 

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



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

 slimy skin. Ventral disk absent. Opercular stay jiresent. Pseudobranehia' present. 

 Gills 3h, without slit behind last. Gill-openiiigs closed below, restricted to small slits 

 under the very small operculum. Operculum very small, strap-shaped. Lower jaw included 

 within the ni)])er. Teeth weak, itaved. First five rays of the dorsal non-articulate, the 

 others grading gradually into the tiexible rays. Pectoral simple, with lowest rays prolonged.
