The type male was taken at Teafontein near Grahamstown. The species 
described by me under the name of C. leppanae (. Records Albany Museum, hi. 
p. io, fig. 3) is probably referable to pictulum, although according to the donor 
of the specimen it came from Bulawayo. Mr S. Hirst has recently supplied 
me with notes on the type of pictulum as follows : flagellum very long and fine, 
reaching well beyond the hind margin of the head-plate, slightly expanded 
and truncate at the tip, the truncated edge being frayed out into short pointed 
processes, visible under the low power of a compound microscope: on the 
second and third legs, the patella has only a single very short spine at the. 
distal end, and the tibia has three dorsal spines. 
In the type of leppanae, there are no stridulatory ridges on the chelicerae: 
the upper surfaces of the chelicerae carry long stiffish bristles: the bristles 
protecting the base of the flagellum are all feathered : ocular tubercle elevated, 
being slightly but distinctly higher above the head-plate than in Solpuga, 
Daesia, Blossia or Chelypus: tarsus IV not spined: claws of tarsus I only just 
visible under a magnification of about 10 diameters. 
The compact fan of feather bristles, protecting the base of the flagellum, 
arises from a short outstanding projection of the surface of the chelicera, and is. 
presumably derived from the distal portion of the series of feather bristles that 
normally fringes the jaw in this family: nevertheless that series is represented 
in piciulum by a row of weakly developed feather bristles, more basally 
situated, and separated by an interval from the fan of stout bristles. The fan 
includes also one or two weak spines or simple bristles. As usual there is a 
row of simple bristles parallel to that of feathered ones. 
The shaft of the flagellum resembles that of Chelypus. It is furrowed along 
its length and seems to be essentially a folded membrane: basally the furrow 
passes into a small inflation on the mesial side. It is rotatable at the base, a 
fact which seems to have been overlooked by Pocock, as well as by myself 
when describing leppanae : possibly the flagellum of other species may be fixed, 
for no one has hitherto recorded a 'rotatable flagellum in this genus.

A. The single series of teeth in the upper jaw composed of four teeth 
in a continuous row, the third being small. Flagellum comparatively 
short, considerably expanded in the basal half but narrower towards, 
the apex. 
1. Apex of flagellum filiform: the basal expanded portion protected on 
the mesial side by one strong spine and beneath it two bristles which are stout 
at the base and filiform at the^apex. C. pallidum Pocock. 
2. Apical portion of flagellum stouter, and bent strongly backwards into a 
hook: on the mesial side, the flagellum is flanked by two strong spines one 
near the base and one near the apex, whilst on the outer side there are three 
stout spines near the basal expanded portion. C. focki Kraepelin. 
B. The single series of teeth in the upper jaw with only two teeth,, 
the basal one much the larger, the distal tooth considerably separated
