1891, pi. XXIX (from Liitken). 

 Careproctiis major, Garman, Discoboli, 1892. 



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

 nostril nottnbnlar. Pseudobrancliiiv reduced to L' lamella'. Vertical lins coiitinnons; anal 

 beginning below tenth dor,-<al ray. Ventral disk longer tban broad, bait length of bead. 

 Skin tbin, loose. 



Eadial formula: D. 42; A. :U; G. 12; P. 34. 



Color, yellowish, mottled with brownish. 



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

 the Kara Sea, where they were obtained at depths varying from 4G to H)(> fathoms. 



This form is ])rovisionally placed in Carcjmniu.s, but we are quite prepared to believe 

 that Gill's ^c</«oc/(/r is a valid genus. The fish has a close external resemblance to the 

 species of Liparis. 



CAEEPROCTUS MICROPUS,(Gunthee), Garman. 



Liparis micropus, Gunther, Challenger Report, xxii, 1887, 66, pi. xii, iig. B. 

 Careproctus microjms, Garman, Discoboli, 1892, 72. 



Head large and thick, abont one-fourth of the total length, the candal included. The 

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

 anterior half of the bead and one-fifth of its length. X<.strils not tubular. (Jleft of the 

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



Vertical fins continnous, 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. (Gihither.) 



Two .specimens, 2 and ;5A 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 8, in 

 540 fathoms.

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



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

 slimy skin. Ventral disk absent. Opercular stay present. P.scudobranchia' i)resent. 

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

 under 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 

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