C(ERE13.V CHLOROPYGA ALLENI. 



Cccreba chloropyga aJleni Lowe, Bull. B. O. C. vol, xxix. 

 p. 86 (1912). 



Certhiola chloropyga Allen, Bull. Amcr. Mus. N. 11. vol. iii. 

 1890-91, p. 348 (Cbapada, Matto Grosso). 



Type. Coll. Brif. jNIus. 



Hab. Cbapada district, Matto Grosso, Brazil. 



Measurements. Wiugs average 58 mm. 



Seven adults (males and females) differ from typical 

 specimens from Baliia in being distinctly paler above and 

 below and in liaving tbe ])ilcum barely dilVerentiated from 

 tbat of tbe mantle. 



Tbus tbe pileum, mantle, and scapulars are pale olive- 

 brown or brownisli olive (Nviugs and tail darker brown), tbe 

 rump is yellowish olive-green, and tbe yellow of tbe under 

 parts is pale citron as compared witb satiVon-yellow. Tbere 

 is no wbite wing-spot, and tbe colour of tbe tbroat-patcb is 

 asby wbite as compared witb greyisb iu typical C. c. chloro- 

 pyga. As compared witb C. c. majuscula tbis race is smaller 

 and paler. 



CffiREBA CHLOROPYGA CAYEXNENSIS, Subsp. nOV. 



Civreba chloropyga Hellmayr, Nov. Zool. vol. xv. p. 112. 



Type. E Mas. O. S. in coll. Brit. Mus., Oyapoc, Cayeuue. 



Hab. Dutcli and French Guiana (lowlands). 



Twelve adult specimens examined. 



It is impossible to ignore tbe fact that examples from tbe 

 Cayenne and Surinam coast-belts differ from typical speci- 

 mens of C. chloropyga from Babia. They appear to be 

 intermediate in coloration between examples from British 

 Guiana (C. guiancnsis) and typical C chloropyga {cf. also 

 Hellmayr, /. c). In case, therefore, it is thought advisable 

 to distinguish tbis geographical race by a distinctive name, 

 I propose tbat of Careba chloropyga cayennensis. 



In the specimens which I have examined from the above 

 localities the pileum is sooty black as compared witli 

 brownish black iu birds from^ Babia, tbe colour of the 

 mantle and scapulars is darker ashy brown, and the rump 

 is distinctly more yellow. There is no wing-spot.
