deep, more or less confluent punctations; the lateral ridges continued 
as a narrow dark border round the posterior end of the scutum; a few 
smaller punctations on the scapulae and on the antero-lateral borders; 
about 20 large, deep punctations in the median area. Emargination 
deep; eyes small and inconspicuous; scapular angles rounded. 
Capitulum: Basis rectangular, distinctly divided into three regions 
-—two broad glossy lateral ridges and a median depressed area containing 
the porose areas; these are long-oval and parallel, the interval rather 
greater than their breadth; cornua short and massive. Palps like 
those of the but with art. 3 less salient laterally. Dentition 3 | 3. 
Ventral surface: Spiracle of the same character as that of the 
but somewhat broader. Legs like those of the

var. intermedia, and R. haemaphysaloides. (Indian Mus., no ~—.) 
The was described (N. and W. xii. 1907) from a specimen taken 
from a horse in the Chin Hills, E. of Chittagong, and sent to us by 
Mr Maxwell Lefroy. We have since seen three <j’s—two taken from 
a buffalo, Agul, Bengal, 31. vn. 1909, by Mr J. L. Bose, and sent to us 
by Mr Howlett, and one taken in the Bombay Presidency in 1912, 
host unrecorded, now in the Indian Museum (no. S.P.A. 383). One of 
Mr Bose’s specimens we were allowed to retain and it is in our collection 
(N. 1220). These males conform precisely to the original description 
except that the “festoon-like bags” behind the anal plates are sometimes 
less conspicuous. It is with some hesitation that we assign this tick 
to the genus Hyalomma. 
Ornithodorus piriformis n. sp. 
Adults small, about 3-5 mm. long, notably piriform in shape, 
especially when not fully distended; brown, with legs and palps often 
yellow. Integument rough, with very numerous close-set mamillae, 
among which the discs are fairly conspicuous. Hairs on integument 
and dorsal surface of the legs very short and rather thick, but not 
clavate. Camerostome without movable “cheeks.” Anus midway 
between the genital aperture and the posterior border; a well-marked 
transverse fold (or paired organ) placed very posteriorly (as in O. meg- 
nini). Two additional lateral folds or slits level with the anus. 
Capitulum rather small, well overlapped by the bluntly-pointed 
hood; hypostome small and feebly armed, bearing very small teeth
