like that of the adult rather than very low. and the snout is also hke 

 that of the adult. It is very doubtful indeed whether the specunens 

 at hand belong to this species, but our material is too small to allow 

 of adequate comparison. 



14. PINGUIPES FASCIATUS Jenyns. 



A single specimen, 120 mm. in total length, from station 2768, off 

 tlie Gulf of San Matias. This is evidently the young of the species 

 described by Jenyns, as it varies in those particulars usual to young 

 of these groups. Tlie eye is much larger, contained 3 J in head, 

 instead of 5, the interorbital space half their diameter instead of one 

 and one-half times; the maxillary reaches under the anterior third 

 of the eye, and the depth is not so great. The two longitudinal bands 

 which are but faintly shown in Jenyns's figure ^ are m the present 

 specmien the most distinct, and may be traced from the upper thhd 

 and the lower margin of the orbit to the last dorsal rays and the 

 caudal spot, respectively. The upper is narrow throughout, about 

 two or three scale rows wide, but the lower is nearly twice the width 

 of the upper, and ends in the widely ocellated black caudal spot on 

 the upper caudal rays. Besides the strong longitudinal stripes there 

 are faint transverse bars, seven or eight broad ones alternating with 

 much narrower ones. 



Dorsal rays V, 26; anal 25; scales with pores m lateral fine 80; 

 m series above lateral line 108; depth 5; head 4^ in total; 3f in 

 body without caudal; eye 3^ in head; interorbital space 2 m eye; 

 distance from tip of snout to end of maxillary 2g in head. 



15. PRIONOTUS PUNCTATUS (Bloch). 



One from station 2766, off Rio de la Plata, and a number from 

 stations 2765, near the same locahty. They are certainly the Prio- 

 notus jJundatus of Cuvier and Valenciennes, by whom the apparently 

 unmdentifiable drawing of Bloch was referred to this species, and 

 that of all subsequent authors. 



16. AGONOPSIS ASPEROCULIS, new species. 



Plate 2, %. 1. 



Type. — 60 mm. in total lengtli, from station 2766, just south of 

 the La Plata River, in 10 or 11 fathoms of water; Cat. No. 76851, 

 U.S.N.M. 



Head in body length to base of caudal; breadth of head, 5; depth 

 at nape, 7j; eye, 31 in head; snout, 4; least width of mtcrorbital 

 space, 6; D. VI, 7; A., 8; pectoral, 13; caudal, 2-11-2; pores in 

 lateral line, 40; branchiostegals, 6.
