CCEREBA NEWTONI (Baird). 

 ST. CROIX BANANAaUII. 



Similar to C. Jlaveola, but white wing-patch truncated posteriorly, 

 yellow of rump tinged with olive, and tarsus longer and stouter. 



This form I have not seen. According to a manuscript description 

 of Professor Baird's, it "has a tinge of ochraceous in the yellow of 

 the breast, as in the Jamaican bird [G. Jlaveola], and like it the throat, 

 though rather lighter, is so dark as not to present any contrast with 

 the black of the cheeks. The rump is more olivaceous-green, not 

 yellow. The white patch at base of primaries is quadrate, as in the 

 St. Thomas bird [C portoriceiisis], without involving the outer webs.' 

 The legs are stouter than in either, the tarsus decidedly longer (17.8 in 

 six specimens). In one specimen the white of superciliary stripe is 

 confluent across the forehead, but not in the others. Young specimens 

 have this stripe yellow, white behind, the throat feathers edged with 

 olivaceous-green. " 



Professor Baird gives the measurements of No. 39380, male adult 

 (no longer to be found in the National Museum collection), as follows: 

 Length (skin), 109.2; wing, 63.5; tail, M.5;^ exposed culmen, 16.8; 

 tarsus, 17.8; middle toe, 9.9. 



measurements differ somewhat, as may be seen below, though not more than do 

 specimens of one form, in other cases, from the same island. In coloration they are 

 closely alike except the back and wings, which in the St. Vincent specimen are 

 blacker and less brown than in the Grenada example. The latter is clearly not C 

 hdeola, the only yellow-breasted species accredited to Grenada by Mr. Cory, and if 

 not C. saccharina is unquestionably most nearly related to the latter form. 

 The two specimens compare in measurements as follows: 



'Doubtless the edges of the outer webs are meant. 

 ^Probably measured from base of coccyx.
