178. Harpe diplotaenia Gill. 



A single young female specimen was obtained by us 

 at Mazatlan. This species is rare in collections, but is 

 apparently not uncommon around the rocky islands. It 

 has been recorded from Cape San Lucas by Xantus, and 

 numerous specimens from the Revillagigedos have been 

 taken by Dr. Gilbert. The form called Har^e ^ectoralis 

 Gill is the male of the same species of which Harpe di-plo- 

 tcBiiia Gill is the female. 



179. Pseudojulis notospilus Giinther. 



This sinall species is cominon in rock pools about 

 Mazatlan, where numerous examples, the largest about 

 six inches long, were obtained by us. It was found in 

 these pools by Gilbert, and has been recorded from Pan- 

 ama by Giinther.
