Pseudojidis adustus Gilbert, Proc. U. S. Nat. Mas., 1890 (Socorro Island). 



Habitat. — Revilla-Gigedos Islands. 



Etymology : Adustus, browned or scorched. 



This species is known from three specimens, the largest 9 inches long; 

 taken by Dr. Gilbert on Socorro Island. 



53. PSEUDOJULIS NOTOSPILUS. 



Pseudojidis notospilus Giinther, Proc. Zool. Soc, London, 26, 1864 (Panama); Giin- 

 ther, Fish. Cent. Am., 447, 1869 (Panama); Jordan & Gilbert, Bull. U. S.' 

 Fish Com., 1882, 108 and 111 (Mazatlan, Panama) ; Jordan, Proc. U. S. Nat. 

 Mus., 1885, 384 (Mazatlan, Panama) ; Jordan, Cat. Fish. N. Am., 99, 1885; Jor-

Habitat. — Panama fauna; Mazatlan to Panama. 



Etymology : Nwtos, back ; gttUoc;, spot. 



This species reaches a length of about 4 inches. Several specimens 

 were taken by Dr. Gilbert in the rock-pools about Mazatlan, and others 

 were found at Panama. As these specimens are not now accessible to 

 us we have taken our analysis from the description and figure of Dr« 

 Giinther. 



54. PSEUDOJULIS VENUSTUS. 



Pseudojidis renustus Jenkins & Evermann, Proc. U. S. Nat. Mus., 1888, 145(Gnaymas). 



Habitat. — Gulf of California.

 Guaymas by Jenkins & Evermann, and also from specimens taken in
