178. Harpe diplotenia 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 Harpe pectoralis 
Gill is the male of the same species of which //arfe diplo- 
tenia Gill is the female. 
179. Pseudojulis notospilus Giinther. 
This small species is common 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.
