ANCHOVIELLA SALVATORIS. new species. 



Head, 3f ; depth, 5; D. iii, 10; A iii, 14?; P. i, 13; V. i, 6; scales 

 (pockets) 38? in median lateral series to caudal base; 9? scales 

 (pockets) transversely at dorsal origin; predorsal scales (pockets) 

 22?; snout, 4^ in head; eye, 3|; maxillarj-, 1^; interorbital, 4; head 

 width, 2^ ; least depth of caudal peduncle, 2 J. 



Body well compressed, moderately long, apparently deepest at 

 dorsal origin, ventral edge rounded convexly and without scutes. 

 Caudal peduncle compressed, its least depth If its length. Head 

 moderately long, well compressed, little pointed, flattened sides con- 

 verging below. Snout short, little pointed wide as long, leng-th 

 three-fourths of eye. Eye large, hind edge slightly advanced to 

 center in head length. Mandible forward to nostril, rami low. 

 Maxillary straight, end rather blunt, slightly beyond preopercle 

 ridge and mandibular articulation. Teeth fine, simple, along entire 

 maxillary edge and slightly larger behind. Mandibular teeth equally 

 large. Few small teeth each side of vomer, row on each palatine and 

 broad patch on pterygoids. Nostrils near last third in snout length. 

 Interorbital broadly convex. Cheek nearly an equilateral triangle. 



Gill-openings forward about opposite front pupil edge. Gill- 

 rakers 20-f-23, finely lanceolate, 1^ in eye. Pseudobranchiae about 

 two-thirds of gill-filaments. Isthmus long narrow ridge, edge not 

 trenchant. 



Scales caducous, apparently narrowly imbricated, with about 5 

 basal striae and 6 incomplete vertical striae above and below margin- 

 ally. Caudal base evidently scaly. 



Dorsal origin about midway between eye center and caudal base, 

 fin base nearly half of head. Anal inserted below last dorsal ray 

 base or a little nearer caudal base than pectoral base. Pectoral 

 (damaged) small, apparently not half way to ventral, which is 

 inserted well before dorsal and depressed fin (damaged) apparently 

 reaching dorsal origin. Vent close in front of anal. 



Color in alcohol largely blackish-slate. Sides of head, iris, and 

 broad lateral band on trunk silvery-white, latter about wide as eye. 

 Fins all brownish. 



Length, 95 mm. (caudal damaged). 



Type.— Cat. No. 83165. U.S.N.M. From Rio Janeiro. Brti/il. 

 Wilkes Exploring Expedition. 



Only the type known. Comparison with Anchoviella hrowni 

 (Gmelin) shows it to differ in the more numerous dorsal and anal 

 rays and larger maxillary. A. perfasciata (Poey) has a shorter 

 maxillary. It is deeper bodied than A. eurystole (Swain and Meek), 

 v/hich has a shorter maxillary and broader silvery lateral band. 

 A. fallida Starks^ has 40 gill-rakers on the lower limb of the first
