THE SHORE FISHES OF PERU 



307 



made by the Mission, by 25 specimens, 35 to 145 mm. (30 to 112 mm. 

 to base of caudal) long, all from the Gulf of Guayaquil, off Puerto 

 Pizarro. A specimen (U.S.N.M. No. 128038), 145 mm. (114 mm. to 

 base of caudal) long, has been selected as the type. The Peruvian 

 specimens differ from 7 specimens, 145 to 150 mm. long, from Panama 

 in having a greater average number of gill rakers, apparently a rather 

 larger eye, narrower interorbital, and the second anal and third dorsal 

 spines seem to be a little longer. However, as the Peruvian specimens 

 mostly are smaller than the Panama ones, the proportions are not 

 entirely reliable. These differences are shown in table 2. The eye in 

 the Peruvian specimens apparently is somewhat more obliquely elon- 

 gate than in the Panama examples, though there is some variation 

 among specimens in this respect.

Range. — Stellifer ericymba has been recorded only from Panama 

 Bay. The range, as represented by the new southern subspecies, 

 peruana, is now known to extend to northern Peru.
