654 REPORT OF COMMISSIONER OF FISH AND FISHERIES. [56] 



This species is known to us from descriptions only. This is the orig- 

 inal Labrus pavo of Linnaeus, and it should retain the specific name 

 pavo, which should not be transferred to Symphodus tinea, the " Crenila- 

 brus pavo " of recent authors. 



62. THALASSOMA STEINDACHNERI.

 Thalassoma melanochir Jordan, Proc. U. S. Nat. Mus., 1886, 384 (name only) ; Jordan 



& Hugbes, i. c, 1886, 68. 



Habitat. — Pacific coast of tropical America ; Acapulco. 

 Etymology: Named for Dr. Franz Steiudachner, the discoverer of the 

 species. 

 Dr. Steindachner observes : 



An example caught at Acapulco agrees on the wbole so closely witb Julis melanochir 

 that I can only on account of its color regard it as a variety of tbat species. 



Julia melanochir comes very abundantly on tbe coast of tbe Sandwicb Islands, and 

 it may from tbence extend its range to tbe west coast of Nortb America, wbicb, on tbe 

 wbole, possesses but few Labroids. 



The characters in our analysis are taken from Steindachner's account 

 of the specimen from Acapulco. 



Inasmuch as the account of the Acapulco fish differs considerably 

 from Julis melanochir as shown in Bleeker's figure, and as the Labroid 

 fauna of the west coast of Mexico is in general wholly unlike that of 

 the Western Pacific, it is probable that the fish from Acapulco is not 

 identical with Julis melanochir. I have therefore given it the provis- 

 ional name of Thalassoma steindachneri.

There seems to be no doubt that Julis detersor, the types of which spe- 

 cies we have examined in Paris, is identical with Th. bifasciatum. The
