not higher than some of the posterior spines; the first and second spines 

 about equal, 2.V in head; the third spine shorter, about equal in length 

 to the fourth, from which it is separated by a wide membrane, which is, 

 however, not at all notched; the spines thence increase in length toward 

 the last; caudal \\ in head; pectorals reaching anal, nearly equaling 

 length of head ; ventrals not reaching vent, li in head. Scales large, 4 

 series above lateral line and 4 below. Color, body and fins uniform black- 

 ish brown ; a few small silvery-white specks on dorsal region, mostly along 

 base of dorsal fin; head and base of pectoral fin with light pink areas and 

 mottlings; snout pink above; nape with a pink cross bar; a dark streak 

 upward and backward from eye to nape; a light streak from eye b;ick- 

 ward to opercle and 1 backward and downward; lower jaw mottled with 

 lio-ht and dark ; a small round, black spot near base of dorsal between 

 twenty-third and twenty-fifth spines, and 1 between twenty eighth and 

 thirtieth, both very faintly ocellated with lighter; slight whitish tips on 

 ventrals and lower edge of caudal. Key West; known from a single 

 specimen, If inches long, taken with the seine in algie on a rocky bottom 

 at Key West. Its congeners, A. marmoratus, A. fasciatus, and A. affinis, 

 were found in the same waters, J. marmoratus being much the most abund- 

 aut of the 4, and reaching the largest size, {nox, night.)

Acanthoclinus, Mocquaed, Bull. Soc. Philom. Paris 1885, 18 (chaperi) ; name preoccupied. 

 Paradinus, Mocquard, Bull. Soc. Philom. Paris 1886, 11 (chaperi). 



Body elongate, compressed, covered with cycloid scales ; mouth large, 

 each jaw armed with an external row of conical teeth, with some teeth 

 behind; teeth on the palate; dorsal very long, continuous, composed 

 entirely of spines, anal with 2 spines; ventrals jugular, with fewrays; ten- 

 tacles on head; gill opening very broad; 6 branchiostegals; lateral line 

 interrupted. Evidently very close to Auchcnoplerus, from which it may 

 be distinguished by the continuous dorsal fin, a character which needs 

 verification. {Ttapd, near; Clinus.) 



2720. PARACLINUS CHAPERI, Mocquard. 



Head 4i; depth 4i. D. XXXI; A. II, 19; P. 13; V. 2; scales 35. Body 

 elongate, very strongly compressed; eye large, equal to snout or inter- 

 orbital width; lower jaw slightly the longer; mouth oblique, reaching 

 front of eye; outer row of teeth strong, canine-like, slenderer and more 

 close set above, below diminishing rapidly in length, the bands of small 

 teeth limited to front of each jaw, a curved group of teeth on palate; 

 dorsal beginning over preopercle, not notched, composed entirely of stout 

 spines; anal equally long; ventrals very narrow, of 2 soft rays, well sepa- 

 rated, the inner slightly longer than outer; head with 3 pairs of ten- 

 tacles, 1 at the nape, tiliform, small, I as long as eye; the second below 

 the orbit, broadened at base, separated into 3 or 4 branches, progressively
