684 REPORT OF COMMISSIONER OF FISH AND FISHERIES. [86] 



This doubtful species is unknown to us. According to Br. Giinther 

 " it has exactly the same coloration (as Sparisoma aracanga), with which 

 it may be easily confounded. " 



104. SCARUS TRISFINOSUS. 



Scar as trispinosus Cuv. & Val., xiv, 182, 1839 (Brazil). 



Pseudoscaros trispinosus Guichenot, Searid^s, 23, 1865 (note on type). 



Scaros quadrispinosos Cuv. &. Val., xiv, 197, 1839 (Martinique) ; Guichenot, Scarides, 



27, 1865 (note on type) ; Jordan, Proc. U. S. Nat. Mus., 1886, 542 (note on 



type). 

 Pseudoscaros qoadrispinosos Goode, Bull. U. S. Nat. Mus., v, 34, 1876. 

 ? Pseodoscarus chloris Giinther, iv, 227,1862 (not Scaros chloris Bloch & Schneider). 



Habitat. — West Indian fauna. 



Etymology : Trispinosus, three-spined. 



We know this species only from the dried skin which formed the 

 original type of Scarus quadrispinosus. It is probably not distinct from 

 Scams trispinosus, likewise based on a dried skin, which, however, we 

 have not examined. 



105. SCARUS ACUTUS. 



Scaros acotus Poey, Mem., ii, 216, 1861 (Havana). 



Pseudoscaros acotos Poey, Syn., 350, 1868; Poey, Enunieratio, 118, 1875 (Havana). 



Scarus gnathodos Poey, Repert., ii, 240, 1860 (Havana). 



Pseodoscaros gnathodos Poey, Syn., 350, 1868 ; Poey, Enunieratio, 119,1875 (Havana). 



Habitat — West Indies. 

 Etymology: Acutus, sharp-pointed. 



We know this species from Poey's descriptions only. There seems to 

 be little doubt that gnathodus is identical witli acutus. 



105b. SCARUS CUZAMILiE. (Plate VII, Fig. 3.) 

 Scaros cozamilw Bean, Bull. U. S. Fish Com., 1888, 196 (Cozumel). 



Habitat — West Indian fauna. 



Etymology: "In allusion to the ancient name of the island" of Co- 

 zumel. 



TJiis species, apparently nearly allied to S. acutus, is known from 

 one specimen about a foot long, taken at Cozumel, by Dr. Bean. 



106. SCARUS VETULA. 

 (Mud-Fish ; Vieja.) 



Vieja Parra, Dief. Piezas, etc., 1787, 58, lam. 28, f. 1 (Havana).

 xiv, 193, 1839 (St. Thomas); Guichenot, Scarides, 25, 1865 (note on type) ; 

 Jordan &, Swain, Proc. U. S. Nat. Mus., 1884, 90.

Scarus superb us Poey, Mem., ii, 218, 1861. 



Pseudoscarus superbus Giinther, iv, 218, 1862; Poey, Synopsis, 346, 1868; Poey, Enuni- 

 eratio, 116, 1875 (Havana). 



Habitat — West Indies. 



Etymology : Vetula, old woman, given in allusion to the Spanish name
