RECENTLY DESCRIBED SPECIES. 405 



pure white ; flanks, thigh-coverts, and under tail- coverts pale 

 earthy brown with a rusty tinge ; breast and abdominal region 

 pale creamy wliite or pale buff, contrasting with the pure white 

 throat ; quills and rectrices liver brown. 



Wing, 3-50 ; tail, 4"25 ; tarsus, M2 ; bill from fore-head, 1-18. 



Described from an individual marked a female, and 

 obtained in the Tonghoo hills by Lieutenant Wardlaw Ramsay. 

 P. Phayrei is its nearest ally ; but in it the entire under sur- 

 face from the chin is bright ferruginous ; it likewise has the 

 entire upper surface of an almost uniform dull olive-brown, 

 with but a faint ferruginous tinge. — A. and M. N. //., June 1875, 

 p. 403. 



Then I have to add a few species described by myself in 

 the Ibis. 



Acrocephalus macrorhynchus, Hume. 



In the Ibis for 1869, p. 357, I provisionally classed this 

 bird as a Phyllopneuste, remarking that it would have to be 

 generically separated. On re-examining the specimen, I do not 

 doubt that it is one of the Calamoherphue, and may for the 

 present be placed amongst the Acrocephali, although it will, 

 I believe, ultimately have to form the type of a new genus. 

 M. Verreaux furnishes the following remarks : — "Except as 

 regards the size, this species much resembles Arundinax 

 olivaceus ; it certainly is not a Phyllopneuste, and has none of 

 the characters of that genus, while it has those of the Calam- 

 oherpince. I have never seen this bird before ; it is not con- 

 tained in our Museum ; and I have not been able to find any 

 notice of it anywhere. I think you may describe it as new." 

 I obtained this species in the Sutledge Valley, in the interior 

 of the Himalayas, not far from Rampoor.
