68 REVIEW OF AMERICAN JULIDIN^. 



This little fish was found iu some abundance at Cape Sau Lucas by 

 Xuatus and at Mazatlan by Gilbert. It reaches a length of about 3 

 inches.

Eahitat— West Indian fauna. 



This species is unknown to us. In describing J. nitiMssima, Professor 

 Goode indicates his suspicion that it is identical with JuUs nitida. One 

 can hardlv think otherwise on comparing his description, taken from a 

 single fresh specimen, with that of Dr. Giinther, taken from three pre- 

 served examples. The agreement seems to us perfect, when we take 

 into account the variations to which the Lahridce are subject. The only 

 tangible distinction would be in the length of the ventrals, two thirds 

 the pectorals in J. nitida and three- sevenths in J. niiidimma.

Habitat—West Indian fauna. 



There seems to be little room for doubt that the Julis deteraor is iden- 

 tical with Th. bifasciatum. The agreement is, as I'oey has noticed, very 

 close in all respects, except that implied iu the remark of Valenciennes 

 that the " spinous dorsal is low and scaly" (" basse et couverte d'ecail- 

 les."). This expression, if intended to mean that the fin is scaly, must 

 be an error.
