erocliroa. The wings and central rectrices are earthy brown with green 

 outer margins, margin of wing yellow, inner wing coverts and inner margins 

 of quills white, a little pale yellow on the axillaries, hack olive, rump 

 yellowish white. Bill dark throughout, without the pale base beneath of 

 M. proregulus. Wing 1*82, tail l - 2, tarsus 0"7, bill from forehead 0*3, 

 do. from gape - 38 inch. 



This appears to me to be an undescribed species. It is possible that it 

 may be Abromis macwlipennis, Blyth, but in that case the measurement of 

 the wing, Ibis 1867, p. 27, given as 2'75 in. must be a misprint for 1*75. 

 This is possible, for the length of the tarsus is misprinted evidently. The bill 

 in the specimen before me is somewhat between that of Reguloides and 

 AbrorniSy but the plumage is that of the former genus. 



Regttloides sp. ? 



This is again a single specimen, and may possibly be a variety of the last. 

 It differs in being larger, but having a still shorter bill, and in the tips of the 

 larger wing coverts being golden yellow, almost orange. There is a yellow 

 tip in the outer web of the last few secondary (tertiary) quills which are in 

 bad condition in the specimen last described, thus adding to the similarity 

 to Abromis maculipennis. The legs appear to differ in colour from those in 

 the speeimen last described. Wing 2, tail 1*35, tarsus - 7, bill from forehead 

 027, from gape 035 inch. 



570. Ctjlicipeta cajsttator, (Tickell). 



Mr. Blyth calls this an Abromis (Cat. Birds As. Soc. Mus. p. 183, and 

 Ibis, 1867, p. 26). Two specimens which I can only refer to this bird are 

 amongst Mr. Mandelli's despatch. The bill appears to me intermediate 

 in form between Abromis and Oulicipeta, whilst the plumage is that of the 

 latter genus, or rather of Reguloides. In fact but for the bill, the skins 

 might be considered small specimens of B. trochiloides. 



As there is no specimen of O. cantator in the Indian Museum, it is just 

 possible I may be in error in the present identification. The birds do not 

 agree very closely with Jerdon's description. The following are then- 

 characters . 



Head greenish dusky above with an irregular whitish central streak, 

 supercilia pale yellow, sides of head mixed dull green and whitish. Back dull 

 green, a little lighter on the rump. Wings and tail brown, edged with green 

 externally, the three outer rectrices on each side having the inner web mar- 

 gined and tipped with white, most broadly on the outer feathers. Tips of 

 wing coverts pale yellow, forming two bars ; edge of wing and axillaries pure 

 yellow ; under parts greenish or yellowish white. Bill dusky above, pale 

 below : feet rather dark.
