This new genus is allied to Circaetus, 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 letters, addressed es 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, 
Walden. 
Sir, —In Capt. J. Hayes Lloyd's very interesting paper on 
the birds of Kattiawar, published in the October number of 
f The Ibis' (p. 399), he -speaks of Palceornis rosa, Buchanga 
ccerulescens, Copsychus saularis, Cyornis jerdoni *, Grauculus 
macei, Zosterops palpebrosus, and, if 1 understand rightly, 
Corvus levaillanti and Crocopus phcenicopterus, 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 Malabar form; nor is there a 
* I think tickellice is the name which has priority for this species, having 
been given by Blyth in 1843 (J. A. S. B. xii. pt. 2, p. 941), whereas jerdoni 
of Gray was not published until 1869 (IIand-1. i. p» 325).
