Haseman : Expedition to Central South America. 34.3 



III al)t)Ut half of tlic details llu' spi-c-iincns listi'd above agree with 

 Cichlasoma coryphxnoides and in the rest with C. temporale as de- 

 scribed by Regan. As my si)eciiTiens are intermediate in size, I 

 regard C. temporale as a synonym of C. coryphcenoides.
