Tonii: Seventeen New Neotropical Birds. 203 



Natural Sciences of Philadelphia), the type locality of guttata, does 

 not differ in any perceptible respect from these Venezuelan skins, 

 which agree fairly well with the figure in Jardine's Contributions to 

 Ornithology, 1851, pi. 69. Hence, as later admitted by Dr. Sclater 

 himself, Calliste chrysophrys Sclater becomes a synonym of Callispiza 

 guttata Cabanis, and a new name is required for the Central American 

 bird — unless, indeed, Calliste guttulata Bonaparte (Comptes Rendus 

 de !' Academic des Sciences, XXXII, 1851, 76), from western Ecuador, 

 belongs here, which seems unlikely, judging from the description alone 

 (I have not seen specimens). Colombian skins will probably also be 

 found referable to this latter form, or else intermediate between it 

 and the Central American form here described. 



Tangara guttata trinitatis subsp. nov. 



Type, No. 31,773, Collection Carnegie Museum, adult female; 

 Heights of Aripo, Trinidad, August 31, 1909; M. A. Carriker, Jr. 



Subspecific characters. — Similar to Tangara guttata guttata from 

 British Guiana and northern Venezuela, but under parts more heavily 

 spotted, and forehead and sides of head more decidedly tinged with 

 yellow. 



Measurements of type. — Wing, 70 mm.; tail, 56; tarsus, 18.5 (tip of 

 bill broken). 



Remarks. — Mr. Ridgway has already (Birds of North and Middle 

 America, II, 1902, 41) called attention to the peculiarities of Trinidad 

 examples of this species, which seem well worthy of formal separation, 

 on the basis of the differences above specified. The new form agrees 

 with true guttata in having the green of the flanks duller and more 

 restricted, and the narrow margins of the black breast-feathers pale 

 nile-blue (instead of pale glaucous green, as in the Central American 

 form). The spotting below, while heavier than in true guttata, is not so 

 heu\y as in custicta, and the forehead and sides of the head are more 

 decidedly tinged with yellow. 



There are thus three, and probably four, readily recognizable races 

 of Tangara guttata. 



Schistochlamys atra aterrima subsp. nov. 

 Type, Xo. 36,818, Collection Carnegie Museum, adult male; Guar- 

 ico, Kstado Lara, Venezuela, February 6, 1911; M. A. Carriker, Jr. 

 Subspecific characters. — Similar to S. atra atra. but anterior portion
