516. ACROCEPHALUS DUMETORUM. 



Neither in habits nor in voice does this species accord with 

 A. streperus [Sylvia arundinacea, Lath.) of Europe, with which 

 Mr. Gould identifies it. It does not affect the vicinity of water ; 

 and the same is remarked by the Abbe Caire (Rev. Zool. 1855, 

 p. 65) of the European A. palustris — so misnamed. Its song is 

 a soft and pleasing warble. The S. montana, Horsf., of Java, 

 referred to by Dr. Jerdon, I now assign to Neornis, Hodgson 

 (sinking Horornis altogether). Ceylon specimens of A. dume- 

 torum appear always to have a distinct greenish shade, but do 

 not otherwise differ from continental examples. 



Dr. Jerdon remarks correctly of A. brunnescens that it differs 

 from the European A. arundinaceus {Sylvia turdoides, Meyer) in 

 the first long primary being ^ inch shorter than the next, 

 whereas in the European analogue the first long primary is, if 

 anything, longer than the second, — and that A. dumetorum has 

 "the same proportions of the quills" as A. brunnescens, the 

 first quill being very minute and pointed, and the second equal 

 to or longer than the sixth. This difference between the Indian 

 and European species of Acrocephalus was first pointed out by 

 myself (J. A. S. B. xv. p. 288). A. brunnescens is of course 

 the Calamoherpe turdoides, from India, of Dr. Jaubert (Rev. 

 Zool. 1855, p. 63). 



518. AuuNDiNAX AEDON (Pall.); A. olivaceus, Blyth (olim) ; 

 Motacilla aedon, Pallas ; Von Schrenck, Reise Amurl. i. tab. xii. 

 fig. 1. 



Common in Eastern Asia, and has been received from the 

 Andaman Islands. Dr. Cabanis erroneously refers Motacilla 

 aedon, Pallas, to Luscinia major, Brehm. » 



519. DUMETICOLA AFFINIS. 



The bird figured as this, by the name Calamodyta affinis, by 

 Gray and Mitchell (111. Gen. Birds, pi. xlix. fig. 2) would seem to 

 be Tribura luteoventi-is (no. 522). I have received from Dr. Jerdon 

 two species of this genus, one of which is the true affinis [Salica- 

 ria affinis, Hodgson j, and the other may be distinguished as 



DUMETICOLA BRUNNEIPECTUS, Sp. nOV.
