male* anil females of Otaria jubata arc both abundant at the Cabo Corrientes, where in 

 the month of I ember they bring forth their young; but of tin- Arctocepkalus I ob- 

 served only in ili'-- The females of the latter are entirely unknown at this point, this 

 species probably repairing to other localities to breed. One of the native gauchos in- 

 formed me that, during the fifteen years he had been accustomed to kill them here, he 

 had never met with a female."
