Specimen 11. 
(Fig. 11.) Hyalomma aegyptium (Linnaeus, 1758), S (N. 2150), from 
a bullock, Lahore, Punjab, India, iv. 1913 ; sent by Major J. N. Mathers 
with other specimens. This is the first example of the kind I have 
encountered in ticks. The specimen possesses a small supernumerary 
leg arising anteriorly from the trochanter of the second right leg ; but 
for its small size the supernumerary leg presents a normal appearance. 
The hosts have been recorded for all of the specimens described 
in 1909 and for 8 out of 11 specimens recorded in this paper. It is 
therefore clear that abnormal ticks, such as are here described, are not 
incapacitated from acting as parasites. 
It appears worthy of note that in 7 out of 10 specimens (including 
the two figured in 1909) showing underdevelopment of one side of the 
body it is the right side which is underdeveloped—this perhaps may not 
be a mere coincidence. It is only in specimens Nos. 2 and 9 and par¬ 
tially in No. 6 that the left side is underdeveloped. In specimen No. 7 
the festoons of both sides are abnormally formed.
