ON TWO COLLECTIONS OF INDIAN TICKS.

Zoologist to the Royal Agricultural Society.

(With 10 Text-Figures.) 
A SMALL but extremely interesting collection of Ticks and other 
Arav^hnids was brought over from Ceylon by Mr C. C. Dobell in 1909, 
and was supplemented by a few tubes sent subsequently by Dr A. Willey 
from the same island. While these were being examined, a large 
consignment of ticks was received from the Indian Museum, Calcutta, 
beino- in fact the whole collection of the museum. The two collections 
O 
may be conveniently dealt with in the present paper, which will give a 
list of the species they respectively contain, and a description of the 
new forms—five new species and three new varieties—which they 
jointly afford. 
The Dobell-Willey collection owes its chief interest, as regards its 
Ixodidae, to the fact that it contains the only parasites hitherto reported 
as taken from the Mouse Deer, Tragidus meminna. These comprise 
two species of Haemaphysalis, both new, and one of them very remark¬ 
able in that it does not conform to one of the most constant characters 
of the genus, its palps being very much longer than broad. 
The Indian Museum collection, drawn from widely separated localities 
and from many hosts, naturally includes a considerable number of 
species, two of which are new. It has also attracted special attention to 
the species Aponomina gervaisi, of which there seem to exist two 
distinct forms, one of which has been relegated to a new variety.
