176. Microspathodon dorsalis (Gill). ( Pomacentrus 
guadrigutta Gill.) 
A single specimen 4 inches in length was obtained in a 
rock pool on the Peninsula called Vijia, by Mr. George 
B. Culver. 
This specimen corresponds almost perfectly to Dr. Gill’s 
account of Pomataprion dorsalis. A smaller specimen 
entirely similar was also obtained. The distinctions be- 
tween this species and Microspathodon bairdii are con- 
stant though slight.
