460 PROCEEDINGS OF THE ACADEMY OF [April 



lection, has been compared with specimens from British Guiana and 

 found to be identical, from which the assumption is apparently safe 

 that it hailed originally from that region, particularly as the birds from 

 Venezuela prove to be different. It is evidently an adult female, and 

 measures as follows: Wing, 95; tail, 73; exposed culmen,20.5; tarsus, 

 24.5; middle toe, 14.5. All the specimens of true meruloides exam- 

 ined are females, and agree in size with those of the same sex of D. 

 meruloides aphanta. The measurements of meruloides given by Mr. 

 Ridgway-' are also based on female examples, and are therefore too 

 small. The name Dendrocinda merulina of Cabanis and Heine-- is a 

 mere puristic emendation of D. meruloides, and must therefore be 

 considered identical in application. 



Dendrocinda meruloides aphanta, subsp. nov. 



Chars, suhsp. — Like Dendrocinda meruloides meruloides, but chin 

 and sides of head usually more grayish; entire upper and lower 

 surfaces, particularly the former, much more olivaceous. 



Geographiced Distribution. — Tobago, Trinidad, and Venezuela. 



Description.— Type, adult female. No. 74,883, U. S. N. M. ; Tobago, 

 West Indies, April, 1878; F. A. Ober. 



Upper parts deep rufescent tawny-olive, darker on the pileum, 

 where the feathers have dusky margins, paler and brighter on the 

 rump, the longest upper tail-coverts chestnut; tail chestnut; wings 

 chestnut, the inner margins of the quills basally ochraceous, the second- 

 aries with terminal shaft streaks of dusky, the outer webs of the outer- 

 most primaries and broad tips of all fuscous, the superior wing-coverts 

 like the back, save for those of the greater series, which are rather more 

 reddish; lores dull brownish-gray; auriculars the same but darker; 

 remainder of sides of head and neck brown like the back; under tail- 

 coverts chestnut, but lighter than the tail; all the remaining lower 

 surface rufescent tawny-olive, like the upper parts, but lighter, the 

 chin and upper throat decidedly grayish ; lining of wing tawny-ochra- 

 ceous. Wing, 92; tail, 73; exposed culmen, 22.5; tarsus, 23; middle 

 toe, 15.
