Type, No. 39,868, A. N. S. P. Kingston, St. Vincent Island, West 

 Indies. February 12, 1914. R. M. Abbott. 



This species is allied, if not likely to prove identical, with Scarus 

 radians Valenciennes, as interpreted by Jordan and Evermann. 

 Sparisoma radians- thus differs in the presence of 4 posterior canines, 

 its reddish-brown color, axil with little or no blue, but with a dusky 

 blotch partly hidden by the fin, caudal nearly plain, and one or two 

 more or less distinct whitish bars across the chin. Scarus lacrimosus 

 Poey is too imperfectly described to permit of positive identification, 

 though the pectoral is without an axillary spot. Jordan notes^ a 

 specimen sent by Poey to Cambridge, which had no dark axillary 

 spot, the head plain, though it possessed two strong posterior canines 

 with several smaller pointed teeth in front. At present Sparisoma 

 abbotti has a dusky front and throat, on each side of the cheek below 

 a whitish horizontal area which does not extend across the chin. 

 Behind the dark area of the throat the scales on the isthmus form a 

 pale or whitish transverse streak completely across.
