[55] REVIEW OF THE LABROID FISHES. 653 



Thalastoma lucasanum Jordan, Cat. Fish. N. Am., 98, 1885; Jordan, Proo. U. S. Nat. 

 Mus., 1885, 384 (Mazatlan) ; Jordan & Hughes, 1. 0., 1886, 68; Jordan, Proc. 

 U. S. Nat. Mus., 1888, 333 (Tres Marias). 



Habitat. — Pacific coast of Mexico. 



Etymology : From Cape San Lucas. 



This little fish was found iu some abuudance at Cape San Lucas by 

 Xantus, and at Mazatlan by Gilbert. It reaches a length of about 3 J 

 inches. 



Our description is taken from three specimens brought from Tres 

 Marias Islands by Alphonso Forrer. 



59. THALASSOMA SOCORROENSE. 



Thalaesoma socorroense Gilbert, Proc. U. S. Nat. Mus., 1890 (Socorro Island). 



Habitat. — Eevilla-Gigedos Islands. 



This species was found by Dr. Gilbert to be abundant about Socorro 

 Island. The 1 ongest of the types is 10J inches. 



60. THALASSOMA NITIDUM. 



Julis nitida Giinther, Cat. Fish. Brit. Mus., iv, 190, 1862 (Jamaica). 

 Thala88oma nitidum Jordan & Hughes, Proc. U. S. Nat. Mus., 1886, 68. 

 Julis nitidissima Goode, Am. Jour. Sci. and Arts, 293, 1877 (Bermuda). 



Habitat. — West Indian fauna. 



Etymology : Nitidus, shining. 



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



Goode indicates his suspicion that it is identical with Julis nitida. 



One can hardly think otherwise on comparing his description, taken 



from a single fresh specimen, with that of Dr. Giinther, taken from 



three preserved examples. This agreement seems to us perfect when 



we take into account the variations to which the Labridcv are subject. 



The only tangible distinction would be in the length of the veutrals, 



two-thirds the pectorals in J. nitida and three-sevenths in J. nitidis- 



sima.
