36 Annals of the Transvaal Museum 
Trappists Monastery near Pinetown. It is named after Lt. W. M. B. Tooke 
to whom the Albany Museum is indebted for the identification and arrange- 
ment of the collection of ticks belonging to that institution 1 . 
The species belongs to the group including hostilis White, and marshalli 
Poc., both of which have been recorded from the Durban neighbourhood (but 
the latter species quite erroneously, I think). In the Mariannhill specimen, 
the second tooth of the upper jaw is quite large, and the distance from the tip 
of the fang to the apex of this tooth is subequal to the distance between the 
apices of the second and fourth teeth: the gap between the second and third 
teeth is in fact not nearly so long as in 5 . marshalli Pocock or 5 . hostilis 
White, which latter species it more closely resembles in the characters of the 
flagellum. 
Dentition. Upper jaw with a terminal fang of moderate length, and not 
upturned: first tooth small, second large, then follows a rather short and 
shallow gap, third tooth rather small, fourth the largest: in the double series, 
the outer row comprises three moderate sized teeth and one small one basally 
situated, whilst the inner row has the first and third teeth of moderate size

but the second and fourth minute. In the lower jaw there is a strong prominent 
crest on the outer side, extending from apex to base. The two major teeth 
are both large and the middle one rather small : between the large distal tooth 
and the small middle one, there is a short but well-defined interval. The fang 
of the lower jaw is not long, the distance from the tip to the apex of the first 
tooth being about if times as long as the distance between the apices of the 
two large teeth. The stridulatory area on the inner surface of the upper jaw 
is ill developed, the ridges being short and weak, and the whole area decidedly 
smaller than usual: there are five ridges present and rudiments of two others. 
Flagellum. The basal enlargement is moderately elongated; the anterior 
bend is in the same vertical as the first tooth; the shaft is narrow and sub- 
cylindrical, passing backwards just above the basal enlargement and extending 
to a point which is a trifle more remote from the hind margin of the basal 
enlargement than this is from the tip of the fang, thus not reaching so far 
as the hind margin of the chelicera. At the anterior bend the flagellum is not 
broadened, its width being less than half the extreme width of the fang at 
this point. Near the tip of the flagellum it presents dorsally a sharp cutting 
edge for a short distance.

African Infantry, fell in action at Fampoux, 12th April, 1917.
