inferiorly and 2-4 on the lower surface. Tibia I with 3 spines at the apex 
interiorly, and a series of long strong spines on the lower surface on its 
posterior side and about 6 or 7 long spines on the anterior side. Patella IY 
without spines. The rastellum at the apex of femur IV superiorly composed 
of short weak spines. Coxa III with stifhsh setae post-ventrally, but the 
patch is not marked off from the setae on the rest of the surface. Claws 
of tarsus IV with an outer row of 3 or 4 teeth and an inner row of about 
7 teeth. 
Posterior sternal sigilla about 1 diameter apart and about J a diameter 
distant from the sternal margin. 
Abdomen with long bristles, but no spines at the base above. 
Posterior spinners. — Apical segment a little longer than the middle 
[segment. 
Ocular area. — Anterior margin of anterior row of eyes in a rather 
.strongly procurved line. Anterior laterals very much larger than any of 
the other eyes : anterior medians comparatively small. Posterior laterals 
■small, their distance from the anterior laterals slightly greater than the 
long diameter of the posterior lateral. 
Measurements. — Total length 13 *3 mm., length of carapace 5 *3. 
Female. 
The female of this species is very similar to that of P. magnisigillata 
mihi, described from Kokstad (Records Albany Museum, III, p. 33). The 
only apparent difference lies in the spinulation of the anterior surface 
of patella IY : in bulcocki the spinuies occur only at the actual base of the 
■segment, whereas in magnisigillata scattered spinuies extend over the 
basal half of the segment intermingled with bristles. There are 8 teeth 
below the chelicerae. Coxa III without a post-ventral tuft of stiff setae. 
The apical segment of the posterior spinners is a trifle longer than the 
middle segment. The abdomen is infuscated throughout except on the 
genital sternite and over the lungs. 
Total length 27 -5, length of carapace 7 -8. 
This species is remarkable in the colouration of the adult male, for 
■so far as is known its contrasted deep black and red colours are not found 
in the males of any other species. Such a combination is well known, 
however, in the genus Stasimopus. 
The genus Pelmatorycter can be divided into two fairly distinct 
groups, according to the presence or absence of a conspicuous tuft of 
closely-aggregated stiffish setae on the post-ventral border of the third 
coxa. 
This tuft is present in the following species : crudeni, dreyeri, 
vryheidensis , and brevipalpis. 
It is absent from magnisigillata , bulcocki, flavidofusulus, sororum, 
pretoriae, and as no mention of this character is found in Dr. Purcell’s 
descriptions I suppose that dentatus, lateralis, o’neili, and schultzei should 
be included here. The character is one which seems to be exhibited more 
distinctly in females than in males, so that it may not be possible in some 
cases to refer an undetermined male to either of the above sections, and 
we may anticipate also that females will be found which are more or less
