 Paz, and the Venados Islands. A large species common in the rocks about 

 Mazatlan. It is seldom caught, and is not eaten. The tyjie here described

dark green or blue, as is that of anal and that of caudal between the points ; pectorals 

 and ventrals yellow, the latter tinged with green toward the edges. Type, a dried skin, 

 not fully grown, from Porto Rico." 



On the same specimen examined by us in Paris we have the following note: "Scarus 

 turchesius. (Cuv. &Val., xiv, 181.) A dried .skin, 0.40 m. long, from Porto Rico. (Plee.) 

 Color faded to a plain brown, paler than in S. coelestinus; no canines. Forehead not very 

 fleshy (young); caudal with its lobes exserted for J to ^ their length ; dorsal, anal, anil 

 ventrals less produced than in the type of Scarus cwlestinus ; scales on cheek in 2 rows; 

 head 3| in lengtli ; depth 3J ; teeth faded, but still partly gxeen." 



*Poey describes Pseudoscarus rostratus as brownish blue, with ultramarine blue on the 

 head and margins of dorsal, anal, and ventral; teeth blue, size rather small. According 

 to him Pseudoscarus turchefdus differs from P. rostratus in having the jaws less terminal 

 and the head uniformly colored ; posterior part of caudal bordered with blue, as is the 

 dorsal and anal.
