middle of the body (not behind, as stated by Kner) with 1 rays, reaching 

 to the vent ; anal with from 17 to 19 rays, beginning under the last 3 or 

 4 rays of the dorsal, and the fin similar in height to the dorsal; 

 caudal equal in length to that of the head from snout to preoperculum, 

 and strongly forked ; pectoral small, pointed, and nearly as long as 

 the caudal. The thin, caducous scales with which the body is covered 

 exhibit no radiating lines, but have simple, delicate, concentric rings. 

 On either side 2 longitudinal rows of inconspicuous phosphorescent 

 spots, surrounded with black pigment ; the lower row near the line of 

 the belly begins near the throat and ends at the origin of the anal. In 

 the space from the pectoral to the ventral are 16 spots ; between the 

 ventral and the anal 11 ; the upper row commences with 2 large spots 

 upon the suboperculum, and continues back to the caudal. Color dark 

 gray ; the back and belly silvery ; all the fins whitish, uniform in color. 

 Specimens taken by the Blake from oflf Grenada in 161 and 461 fathoms, 

 in the old Bahama Channel in 500 fathoms, and off Bequia in 458 fathoms; 

 the original type from the open Atlantic. (Goode & Bean.) (brevis, 

 short; dens, tooth.)

Bonapartia, GOODE & BEAN, Oceanic Ichthyology, 102, 1895, (pedaliota). 



Body oblong, compressed, slender behind, as in Gonostoma, covered 

 with large cycloid scales, nearly equal in size. A continuous row of pho- 

 tophores on either side of the ventral line upon the lowest row of scales, 

 extending from the anterior part of the lower jaw to the extremity of 

 the base of the anal ; others upon the caudal peduncle. Head much com- 

 pressed, cleft of mouth very wide. Premaxillary short ; maxillary long, 

 curved, forming the entire margin of the upper jaw, extending to the 

 angle of the preoperculum. Jaws armed with a single series of not very 

 numerous, acicular teeth, uniform in size; minute teeth on the palatines 

 and pterygoids. Eye moderate. Pectoral and ventral fins small ; dorsal 

 fin on the hinder half of the body, opposite the anterior portion of the 

 anal; adipose fin absent; anal much longer and higher than dorsal; 

 caudal (probably) subtruncate. Gill opening exceedingly wide, the 

 branchial aperture-extending nearly to the dorsal line on either side, and 

 extending forward also to the symphysis of the lower jaw. Gill rakers 

 very long. (Named for Charles Lucien Bonaparte, Prince of Canino, 

 1775-1840, " whose admirable work upon the fishes of Italy, one of the 

 most essential of the older works in the ichthyologist's library, is 

 full in its discussion of the fishes allied to the one now under discussion.")

 compressed. Eye about equal to snout ; width of interorbifcal space less
