This new genus is allied to Circa'etus, from which it differs 

 in its short wing and long tail. The latter is nearly as long 

 as the wing itself, the difference between them being less than 

 the length of the tarsus. It differs from Herpetotheres, in 

 which Prof. Schlegel was inclined to place it, in its oval nos- 

 trils, and from Spilornis in its lanceolate crest as well as the 

 proportions of the wing and tail.

The following lettei's, addressed " To the Editor of ' The 

 Ibis/ " have been received : — 



Chislehurst, October 1873. 

 Sir,— In the year 1845 Mr. Blyth (J. A. S.B. xiv. p. 589) 

 described a rare and beautiful species of the genus Troglodytes, 

 Vieillot, from Darjeeling, and named it T.punctatus. As this 

 title had been previously bestowed in 1823 by C. L. Brehm 

 on the common Wren of Europe (Naturgesch. europ. Vogel. i. 

 p. 318), I propose the name of T. formosus for the Dar- 

 jeeling species. 



I have the honour to remain. 

 Yours, 



Walben. 



Sir, — In Capt. J. Hayes Lloyd^s very interesting paper on 

 the birds of Kattiawar, published in the October number of 

 'The Ibis' (p. 399), he speaks oi Palceornis rosa, Buchanga 

 ccerulescens, Copsychus saularis, Cyornis jerdoni*, Grauculus 

 macei, Zosterops palpebrosus, and, if I understand rightly, 

 Corvus levaillanti and Crocopus phoenicopterus, as "Malabar 

 forms.'' As I have myself used the term '' Malabar forms " 

 or " Malabar fauna " in speaking of birds, will you pardon 

 my remarking that I have employed it in a different sense 

 from Captain Hayes Lloyd. I should not have called any of 

 the birds above mentioned a jMalabar form ; nor is there a 



* I tliiuk tickellm is the name whicli has priority for this species, having 

 been given by Blyth in 1843 (J. A. S. B. xii. pt. 2, p. 941), whereas yerJom" 

 of Gray was not published until 18G1) (Ilaud-l. i. p. 325).
