origin of anal, its base 3.4 to 3.6 in head; caudal moderately forked, 

 the upper lobe much longer and more sharply pointed than the lower 

 one; anal with concave margin, its base 1.75 to 2.0 in head; ventral 

 failing to reach origin of anal in male, somewhat beyond origin in 

 large females and with thick integument on inner surface, inserted 

 rather nearer middle of base of anal than base of pectoral spine; 

 pectoral failing to reach ventral by at least twice diameter of eye, the 

 spine rough on outer margin, and barbed on inner margin, rougher in 

 male than female, failing to reach tip of longest soft rays by diameter 

 of eye, 1.5 to 1.75 in head. 



Color of rather recently preserved specimens metallic blue above, 

 shading into silvery on side ; pale underneath ; fins more or less dusky, 

 inner surfaces of pectoral and ventral black, becoming pale distally; 

 caudal with a very narrow black margin. 



Figure 27. — Galeichthys jordani (Eigenmann and Eigenmann). From the type of G. 

 simonsi Starks, 255 mm. long, Callao, Peru (U.S.N.M. No. 53466). (After Starks, 1906.) 



Two females, 290 and 340 mm. (230 and 262 mm. to base of caudal) 

 long, were taken in the harbor at Cabo Blanco by the Mission. One 

 was caught with a hand line and the other in a trammel net. In 

 addition, the type of G. simonsi (U.S.N.M. No. 53466), 255 mm. 

 (208 mm. to base of caudal) long, from Callao, and one specimen 

 (U.S.N.M. No. 77735), about 335 mm. (256 mm. to base of caudal) 

 long, taken by E. E. Coker at Tumbes, were measured. The fore- 

 going description is based on the four specimens mentioned. Several 

 small specimens (U.S.N.M. No. 77580) taken at Cap6n by R. E. 

 Coker and one (U.S.N.M. No. 101842) secured at Callao by W. L. 

 Schmitt also were examined. The Peruvian material was compared 

 with specimens from Panama, and it was learned thereby that the 

 Peruvian specimens are identical with G. jordani, rather than with 

 G. seemanni, with which G. simonsi, based on a Peruvian specimen, 

 had been synonymized by several authors. G. jordani, which is 

 rather closely related to G. seemanni, is characterized by the large 

 eye; the rather fiat deep snout with nearly vertical edges; the smooth
