1871.] MR. R. SWINHOE ON THE BIRDS OF CHINA. 355 



Amoy ; Canton ; Pekin (David) ; Lake Baikal (Tacsanowshj). 

 Has been shot in Europe. 



I have lately received from Trans-Baikal a bird of this group, 

 which I at first thought might be Calamoherpe maackii, of V. 

 Schrenck ; but it seems to be a novel form, and I would propose to 

 designate it 



LOCUSTELLA TACSANOWSKIA, n. Sp. 



Bill black, bright yellow on the basal half of the lower mandible. 

 Legs and toes yellowish flesh-colour. Upper parts olive-brown ; 

 wing- and tail-feathers hair-brown, broadly margined with olive- 

 brown. Underparts and slight superciliary streak yellowish, with 

 the breast, flanks, and tibiae washed with olive-brown. Length 

 5 inches; wing 2*2; tail 1*9, much graduated, outer rectrix T 6 ^ short- 

 est. First primary of wing broad, '6 long, second | inch shorter 

 than third, which is slightly shorter than the fourth. 



The nearest in form to this bird is the Locustella ochotensis, from 

 which, however, it can readily be distinguished by its smaller size, 

 short and blunt bill, unspotted upper parts, and light untipped tail. 



The Curator of the Museum at Warsaw, M. Tacsanowski, sent 

 this bird to M. Jules Verreaux, labelled Dumeticola thoracica, 

 juvenis. It is likely to occur as a winter visitant in China ; but as 

 it has not been yet found in that country, I do not number it in my 

 list.

 Calamodyta affinw, Gray & Mitch. G. of B. pi. 49. 



Sent to the Paris Museum by Pere David from Moupin.

 Curruca garrula, Bris. Av. iii. p. 384. n. 7. 



Very rare at Pekin, but common at Ordo (David). Mr. Gould 

 has a specimen from Kalgan.

132. OREOPNEUSTE DAVIDII. 



Abrornis davidii t Milne-Edwards, Nouv. Arch. d. Mus. 1864, t. i. 

 pi. 2. fig. 1. 



In structure this species is neither an Abrornis nor a true Phyllo- 

 pneuste, and may with propriety be ranked in a separate genus in 

 company with P. agricolensis, Hume, of India. In coloration it 

 resembles my Araudinax Jfemingi, and might at the first glance be
