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

 wide, separate. 



POROMITRA CAPITO, GoonE and Beax. (Figure 200.) 



Poromiira mpito, Goode aud Bean, Proc. U. S. Nat. Mus., 1882, 215; Bull. Mus. Conip. Zoiil., x, 215.— Gt-N- 

 TiiER, Challenger Report, xxii, 34.— Jordan, Cat. Fish. N. Anier., 1885, 75. 



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

 one-half its height. Scales as large as the pupil, with concentric strise, about twenty-four 

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



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

 AleiwcepMluit Bairdii. 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 pei]iendicular fiom the posterior limb of the pupil. 

 Tlie 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 6 

 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 liom 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. 



Eadial formula: D. vii or VIII, 0; A. 9; V. 7 or 8; V. 12; C. 15. 



Two specimens of this species were secured by the Blale; one trom station cccxxvill, 

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

 unknown locality.
