which gradually give place to 2 rows on the sides instead of being

Bairdiella vere-crucis 1s probably the species obtained by Stein- 
dachner from the Rio Magdalena (Atlantic) in 1878 and classified 
as Corvina (Homoprion) acutirostris, a species (identical with B. 
armata) which he had described in 1875 from Panama Bay. He 
mentions the fact that the Kast Coast specimens show ‘ eine etwas 
stiirker gerundete und ein wenig ktirzere Schnauze,”’ and notes also 
the somewhat larger preopercular spines and the longer second anal 
spine. 
Direct comparison of the two species, Bairdiella vere-crucis from 
Vera Cruz (Atlantic) and Bairdiella armata from Panama Bay 
(Pacific), leaves no doubt that the two are distinct although un- 
doubtedly representative or “ geminate ” species. 
The type of Bairdiella vere-crucis is Cat. No. 61676, U.S.N.M.; 
Cotypes are in Stanford University.
