Trichoor. A larger specimen, from the more southern part of 
the Travancore range, was reported in the ‘ Annals’ for Decem- 
ber 1862. The original site proves to be a portion of the 
Anamullay Hills, which Mr. W.T. Blanford describes, in p. 374 
of the ‘ Journal of the Asiatic Society’ for 1861, as the highest 
range in Southern India, lying south-west of Coimbatore and of 
the Nilgiris, where Mr. King made a collection which he after- 
wards lost. Mr. Blanford informed me that one of the shells 
taken was evidently H. Basileus. In a short paper by Dr. Pfeiffer, 
published in the ‘ Proceedings of the Zoological Society’ for 1862, 
p- 117, a large Helix, 68 mill. in diameter (4 mill. less than my 
original specimen), is described under the name of H. Titanica, 
as taken in the Anamullay forest. It is evidently the same 
species as H. Basileus. Dr. Pfeiffer must have overlooked the 
description which I forwarded to him in May 1861. 
Another Helix, 30 mill. in greatest diameter, 25 mill. in the 
lesser, and axis 17 mill., taken, with smaller varieties, by Lieut. 
Cox in the same quarter, agrees with H. deta, Pfr. (not H. leta of 
Gould), the habitat of which was unknown. From the south 
part of the Travancore range I have received an imperfect speci- 
men of a Helix which is apparently H. Isabellina, Pfr., previously 
known from Ceylon. This is an interesting circumstance in 
connexion with Dr. Pfeiffer’s description, in p. 116 of the ‘ Proce. 
Zool. Soc.’ for 1862, of a Cataulus (C. recurvatus) from the 
Anamullay forest. 
In October 1860, I described a small Cyrena from Quilon as 
C. Quilonica ; and in December 1862, I noted it as a Batissa, 
from a more mature specimen. I have since obtained the shell 
fully grown from Cochin, and find that it was described in the 
*Proc. Zool. Soc.’ for 1858, by Mr. Sylvanus Hanley, as Cyrena 
(Batissa) Cochinensis, which name will be retained on the ground 
of priority to that of Quilonica.—W. H. B.
