freniinvillel from the Galapagos, The plate published by Valen- 

 ciennes, however, proves our Galapagos specimens to be D. frendn-

Family SCI^F]NID.F.. 



66. ARCHOSCION ANALIS (Jenyns). 



A specimen collected at Callao, Peru, the tyy^e locality of the species. 



67. CYNOSCION ALBUS (Gunther). 



A small specimen from Guayaquil, agreeing well with Panama 

 specimens. 



68. BAIRDIELLA CHRYSOLEUCA (Gunther). 



Three specimens ivom Gua3'aquil difl'er slightl}^ from specimens 

 from Panama. The anal rays are 7 in one specimen and 8 in the other 

 two (9 in Panama specimens). Thei-e is a considerably longer distance 

 between the tips of the anal rays and the ])ase of the caudal in the 

 former specimen, and a slightly longer distance between these points 

 in the other two than in the specimens from Panama. As usual, the 

 Guaj'aquil specimens are much darker. No other difference is appre- 

 ciable, however, and these dili'erences will probably be found to fall 

 within the range of variation of the species. 



69. BAIRDIELLA ENSIFERA (Jordan and Gilbert). 



A couple of specimens from Guayacjuil, Ecuador, ditfer f lom Panama 

 specimens only in being darker. 



70. STELLIFER MINOR (Tschudi).
