(2 j 2) on its lateral borders. Bristles on the basis capituli inconspicuous, 
but two are present at the origin of the hypostome, near the middle. 
Legs. Coxae small, subequal, slightly chitinised, differing little in 
texture from the general ventral surface; all the tarsi long and sharp- 
pointed ; tarsus I prominent in the region of Haller’s organ, but other¬ 
wise without humps; tarsi II-IV tapering gradually to a point. Pads 
distinctly large for Argasidae. 
Described from 15 specimens taken at Mahabaleshwar, Satara 
District, at a height of 4200 ft. (? host) by F. H. G., 13-16. iv. 12.

The only known Ornithodorus with similar tarsi is 0. talaje, but from 
this it is easily distinguished by the absence of movable “cheeks” to 
the camerostome, as well as by its much finer mammillation. 
Ornithodorus asperus n. sp. 
Resembling 0. talaje in size, shape and general configuration, and 
possessing, like 0. talaje, movable “cheeks” to the camerostome, and 
similar ventral folds and posterior paired organ. 
Easily distinguished from 0. talaje by its integument and its tarsi. 
The integument is very finely mammillate, the mammillae being 
much smaller and more pointed than in 0. talaje, giving the whole surface 
a very rough texture. Simple hairs, short, but longer than in 0. talaje, 
are scattered over the surface. They are longer and rather conspicuous 
on the hood. The tarsi are distinctly humped, and the dorsal surface 
of tarsus I is raised in a succession of slight rounded elevations (see 
Fig. 3) (the tarsi of 0. talaje taper without any prominences). 
Hypostome well furnished with sharp teeth at its distal extremity. 
Four bristles under the basis capituli. 
Described from a single specimen, numbered 296 in the Berlin 
Museum, and taken on the Bileck Steppe, Mesopotamia by Dr Kohl, of 
the Expedition of Baron M. v. Oppenheim, 22. v. 1913. No host 
recorded.
