three fifths length of head. Second dorsal beginning over middle of 

 anal, terminating slightly in advance of its last ray; the first rays high- 

 est. Origin of anal considerably nearer snout than base of caudal. 

 Base of anal oblique, the anterior rays much highest, the posterior 

 very short. Caudal deeply forked. Ventrals short, not reaching front 

 of anal. Pectorals verj'^ broad and short, slightly falcate, scarcely 

 longer than distance from snout to posterior margin of pupil. 



Scales adherent, with entire edges. 



Color transparent, with a wide, very sharply-defined, silvery band 

 along sides, mai glued above by a narrow dark line; this band abinptly 

 coiuitricted near the middle of the caudal peduncle and again widened 

 at base of tail into a silvery blotch without dark edging; opercles and 

 branchiostegals silvery; lips i)unctulate with black dots; silvery peri- 

 toneum showing through walls of abdomen; caudal dusted with black j 

 a black point at base of each dorsal and anal ray. 



Head, 4 in length; depth, 4^-.

We refer this species to the genus Atherinella of Steiudachner, with- 

 out raising the question of the distinction of the latter group from 

 Atherina pro[>er. Atherinella eriarcha is known to us from a single 

 young specimen (Xo. 29243 U. S. Nat. Mus.),2J inches in length, found 

 in a rock pool at Mazatlan. It is distinguislied from A. panamenais 

 Steind. by numerous characters, notably the much longer anal and 

 shorter pectoral tins. 



15. Caranx vinctus, sp. nov. (28365, 28366.) 



Allied to C. cibi Poey. 



Body elongate, elliptical, compressed, upper profile evenly arched 

 from snout to caudal peduncle, tiie lower nearly rectilinear from snout 

 to origin of anal fin ; upper profile slightly carinate anteriorly. Width 

 of cheek about equal to diameter of eye. Mouth moderately oblique, 

 the jaws subequal, the lower scarcely included; intermaxillaries ante- 

 riorly about on a level with axis of body, just below level of lower margin 

 of eye; maxillary reaching vertical from front of orbit, 3 in head; teeth 

 very small, blunt, in a narrow band in each jaw, becoming a single series 

 in sides of mandible; the outer series slightly enlarged; teeth on vomer, 

 palatines, and tongue similar to those on jaws. Gill-rakers very long, 

 numerous; the longest, two-thirds diameter of orbit, their number about 

 10-27. Eye large, less than length of snout, about equaling interorbital 

 width, 4 in head. Adipose eyelid moderately developed. Preopercle 

 with its posterior margin very oblique, the angle broadly rounded. Pre- 

 orbital thin, its least width three- tilths diameter of orbit. 



Spinous dorsal well developed, the spines high and flexible ; the antrorse 

 spine well developed; the iburth spine the longest, the fifth but little 

 shorter ; those posterior rapidly de;'reasing ; the fourth spine equals two- 

 fifths length of head; length of longest dorsal ray less than one half
