66 REVIEW OF AMERICAN JULIDINiE. 



Lower and Sontberu California and readies a length of 7 inebes. On 

 tbe ruletbat "once a synonym, always a synonym," now adopted by most 

 American ornithologists and ichthyologists, the name modcHtus must 

 give x)lace to caUfornlcus. 



Genus 3. PSEUD OJULIS. 



Pseudojulis Bleeker, Proc. Zool. Sue. Loudon, 1801, 412 (girardi). 



This genus contains two or three species similar to riatyglossus in all 

 respects except in the absence of the posterior canines. From Oxyjulls 

 they differ in having the dorsal spines sharp. But one American spe- 

 cies is known. 



ANALYSIS OF AMEKICAX SPKCIES OF I'SEUDOJULIS. 



a. Caudal lin rounded; ventral iiu with the outer ray not pi'oduced, its lenj^tli not 

 nearly twice that of inner ray ; its tip not reaeliing tip of pectoral ; scales before 

 dorsal in about six series; body rat her stout, the depth Hf in the length; snout 

 pointed; profile not steep ; dorsal spines jjungent; olive, young with a silverj' 

 lateral streak ; back with four or live indistinct broad dark cross- bands, these 

 forming blotches on the dorsal tin, one of these on the fir«t three soft rays, larg- 

 est and black ; angles of caudal pale ; ventrals whitish, with a broad black outer 



margin Notospilus, 11. 



11. Pseudojulis notospilus. 



Pseudojulis notospilus Giinther, Proc. Zool. Soc. London, 2G, 1864 (Panama); 

 Giinther, Fish. Cent. Am., 447, 1SG9 (Panama); Jordan & Gilbert, Bull. 

 TT. S. Fish Comm.,1882, 108 and 111 (Mazatlan, Panama); Jordan, Proc. 

 U. S. Nat. Mus., 1885, 384 (Mazatlan, Panama); Jordan, Cat. Fish. N. 

 Am., 99, 1885. 



Habitat. — Panama fauna; Mazatlan to Panama, 



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

 were taken b}' 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. 

 (Tiinther, 



Genus 4. THALASSOMA. 



Julis species, Cuvier & Valenciennes, XIII, 1839 (not type). 



Thalassoma Swainson, Nat. Hist. Class'n Fishes, II, 1839, 224 {piirjyiircKs). 



Chlorichthys* Swainson, 1. c, II, 1839. 232 (bifasciatus, &c.). 



Julis Giinther, Cat. Fish. Brit. Mus., IV, 1862, 179 (not of Cuvier nor of Swainson). 



This genus as here understood comprises numerous species, similar 

 in most respects to the species of PlatygJossus, but with only 8 spines 

 in the dorsal fin and without i)osterior canines. The species belong 

 mostly to the Pacific and Indian Oceans, those of the Atlantic being 

 few. 



The group Thalassoma of Swainson, distinguished b^' him from 



* " Chlorichlliiin and Iditliijvtdliis, cunfii.sed Jumbles of .s])ecics, may well Ix; disposed 

 of as synonyms of Thalassoma aud Coris, respectively, although several other genera 

 are represented in each." (Swain, Proc. Ac. Nat. Soi. Phila., 1882, 275.)
