AUGUST, 1915. NOTES ON SOUTH AMERICAN BIRDS CORY. 325 



spots on outer webs of primaries fewer and narrower, and the outer 

 rectrix black and white. 



Cerchneis sparveria intermedia subsp. nov. 



Type from Villavicencio (alt. 1600 ft.), base of eastern Andes, 

 Colombia. Adult male, No. 121449, American Museum of Natural 

 History, New York. Collected by Chapman, Cherrie, et al., March 14, 



Range: Andes region of Colombia, from Cundinamarca and 

 Bogota southward. 



Characters: Adult male. Similar to C. s. ochracea in its deeply 

 colored ochraceous cinnamon and practically unspotted under parts, 

 but differs in averaging somewhat larger; black subterminal band on 

 the rectrices much shorter, and more pronounced white markings on 

 the outer webs of second and third (outer) primaries. The type speci- 

 men has the inner web of outer rectrix barred with black and white, 

 with a tinge of rufous near the shaft on the basal part. 



Male: Wing, 189; tail, 127; tarsus, 37; greatest breadth of black 

 tail band (measured at shaft of feather), 20 mm. Average measure- 

 ments of seven males from Villaviciencio, Honda, Magdalena River, 

 and Bogota: Wing, 177 to 189, average 185; tail, 124 to 132, average 

 129 mm. Seven males from Cundinamarca, which are apparently 

 this form, average decidedly larger: Wing, 188 to 199, but the tail 

 measurements (126 to 132) and the subterminal band on the tail (18 

 to 22) average about the same. 



Female: Wing, 194; tail, 139 mm. 



Comparative differences: The practically unspotted and deeply 

 colored under parts will readily distinguish males of this race from other 

 South American forms except C, s. ochracea and C. s. andina. From 

 the former it differs in averaging somewhat larger ; in the much narrower 

 black tail band (varying from 18 to 22 mm.; while in ochracea it varies 

 from 28 to 34, averaging about 29) ; and in the much more pronounced 

 white markings on the outer webs of the second and third (outer) 

 primaries, the second having two spots or streaks and the third three 

 well marked spots (in ochracea the second is plain or with one small 

 spot, and on the third the three spots are small and narrow). From 

 C. s. andina it differs in averaging smaller in size; much shorter tail; 

 somewhat broader tail band; much smaller and less numerous white 

 spots on the outer webs of the outer primaries (in andina the white 

 spots are much larger, and are present on the fourth, fifth, and often 

 the sixth outer primary, as well as the second and third) , and in purer 

 white under wing coverts.
