86 BULLET'Il*r 95, UNITED STATES NATIONAL MUSEUM. 



A. Ill, 8; scales 7-44 (+3) -15 ; first dorsal spine 8.71 in head, second 

 5.58, third 2.31, fourth 2.06 ; second anal spine 1.94, third 3.08 ; ven- 

 trals 1.72 ; gillrakers 6+15, rather short, longest 3.8 in eye. 



Body ovate, compressed, dorsal outline strongly arched, ventral 

 outline compartively straight to base of anal. Snout long, pointed, 

 conical; a slight depression over eyes; interorbital broad and flat; 

 mouth small, nearly horizontal, maxillary scarcely reaching vertical 

 from anterior border of eye; teeth in narrow villiform bands; nos- 

 trils much nearer eye than tip of snout, the anterior nostril with a 

 large flap, partly covering posterior nostril; preorbital broad, 

 slightly wider than eye ; margin of preopercle finely and evenly ser- 

 rate. First dorsal spine short, slightly more than 1.5 in the second ; 

 second about 2.46 in third, which is a little shorter than the fourth ; 

 eleventh dorsal spine 1.5 in the twelfth, the latter is considerably 

 shorter than the longest rays; the second anal spine is very long, 

 longer than the soft rays, broad at base and tapering to a point, third 

 anal spine shorter and much weaker; ventrals reaching to within 

 half a diameter of eye from vent; ventral spine strong; pectoral 

 long, tip reaching to vertical from base of second dorsal ray ; spinous 

 dorsal fitting into a well-developed sheath of scales, a narrow sheath 

 at base of second dorsal; the sheath at base of anal half as wide 

 as eye. 



Color in alcohol, brownish, with traces of silvery ; fins dusky. 



We have provisionally identified this example as P, schyri. From 

 P. macracanthus, which it closely resembles, it differs mainly in hav- 

 ing a narrower interorbital; and from P. hurro it differs in having 

 well-developed serrations on the edge of the preopercle; its dorsal 

 spines are longer and the eye is smaller. The type of P. hurro ap- 

 pears to be an old individual and its dorsal and anal spines are 

 grooved and much worn at the tips. P. andrei (Sauvage) from 

 the Guayas River near Guayaquil, Ecuador, is evidently a very 

 closely related form.
