751. CONOCABA MACDONALDI, Goode A lican. 



Head "ik in total length; depth 5f to base of caudal; thickness 12; eye 

 5, 2 in snout; snout 2i. D. 18; A. 36; P. 10; B. 6; V. G; C. 22^ scales 

 200. Body elongate; snout compressed, and with an obtuse point; the 

 lower jaw included. Mouth large, the upper jaw about \ length of 

 head; the maxillary not reaching to front of eye; mandible reaching 

 to below middle of eye. Teeth on the premaxillary, vomer, and palate 

 very sharp, minute, widely separated, in a single row in each jaw. Nos- 

 trils lateral, posterior very much larger, their distance from eye \ 

 the length of eye. Gill openings wide; opercular apparatus mem- 

 branous, its elements being very imperfectly ossified. Fifteen gill 

 rakers on the first arch below the angle. Scales very small. Dorsal fin 

 short, about \ as long as anal fin, its posterior rays inserted nearly 

 over last rays of the latter, distance of its insertion from tip of snout 

 about 5i times its own length ; anal inserted at a distance from the 

 snout equal to 2^ times its own length ; ventral inserted nearly midway 

 between the snout and the base of the caudal ; pectoral short, twice 

 diameter of eye, and inserted below median line of body ; caudal fin 

 short, its middle rays not more than f length of snout, forked. Color 

 uniform deep blue-black in life. 



A specimen 8i inches in length was obtained by the Blake at station 

 CLXXii, in 24° 36^ N. latitude, 84° y W. longitude, at a depth of 955 

 fathoms, and another, 6 inches long, from station clxv in latitude 24° 

 36^ N., longitude 84° 05' W., at a depth of 955 fathoms. Another, Si 

 inches long, was taken by the Albatross at station 2392 (latitude 28° 47'' 

 30'^ longitude 87° 270- (Goode & Bean.) (Named for Hon. Marshall 

 McDonald, Commissioner of Fish and Fisheries.)

752. rOXOCARA MACROPTERA (Vaillaut). 



Head elongate, 4 ; depth 8 ; thickness 11 ; snout 2*, compressed, with 

 an obtuse point ; eye large, 3^ in head, 5^^ in interorbital width. D. 21; 

 A. 40; P. 8; V. 5; B. 6. Scales more than 100. Mouth moderate, the 

 upper jaw extending considerably beyond the lower, the maxillary 

 scarcely reaching to the anterior margin of the orbit- Teeth on premax- 

 illaries, maxillaries, vomer, and palatines, conical, elongated, rather 

 small, and in a single row in each jaw. Nostrils wide, close together, the 

 anterior near the middle of the length of the snout; gill opening wide; 

 operculum for the most part membranaceous, its elements being very 

 imperfectly ossified ; preoperculum curved, thickened on its anterior edge ; 

 the interoperculum and suboperculum not prominent, apparently replaced 

 in part by the branchiostegals. Gill rakers about 15 below angle. Vent 

 a little behind the middle of total length. Lateral line extending from 

 the upper part of the branchial opening to middle line of body. Scales 

 remarkably small, those of lateral line very simple. 



Dorsal with its outline a little convex, lower behind, and ending at a 

 distance from the caudal equal to the length of its own base, which is 

 equal to about 8 in body ; anal more than twice as long, beginning near
