to a second series of Idiops were taken in the Pretoria 
neighbourhood at Zwartspruit and described by me under 
the name of I. gunningi (Records Albany Museum II, 
p. 417). It is, however, uncertain which, if either, of 
these two species is co-specific with pretoriae. The recent 
discovery of an undoubted male of pretoriae at Saltpan 
enables us to fix a precise locality for the species.

p. 91). — Female. 
1. versicolor (Pure.), from Umtali (Ann. S. Af. Mus. Ill, 
p. 90). — Female. An important character of the species 
not mentioned in the description, but found in Dr. Purcell’s 
key (Trans. S. A. Phil. Soc. XY, p. 118), is the presence of 
short sninules on the anterior surface of the coxae of the 
first two pairs of legs. 
I. pungivensis , Pure., from Pungwe Riy. (Trans. S. A. Phil. 
Soc. XV, p. 116).— Male. 
7. pallidipes , Pure., from S. Hereroland, and 7. striatipes, 
Pure., from Sekgoma, in the Kalahari (Jena. Denkschrift 
XIII, pp. 206-207), are based on specimens which are in 
all probability very immature, and the characters of the 
species will not be fully known until adult material is 
obtained.

7. gerhardti , Hewitt, from Doornkop, near Belfast (Rec. Alb. 
Mus. II, p. 420). — Female. The type is perhaps not quite 
mature. Its most striking character is the longitudinal 
elongation of the posterior eyes. 
7. parvus , Hewitt, from Holfontein, O.F.S. (Rec. Alb. Mus. 
Ill, pt. 2).— Female. 
7. castaneus , Hewitt, from Hewington (Rec. Alb. Mus. II, 
p. 420), is based on a young example and should not have 
been described. 
Acanthodon transvaalensis (Mihi) var. nov. paucispinulosus . 
Types. — Two adult female examples and several juveniles from 
Gravelotte, near Leydsdorp, collected for the Transvaal Museum by 
Mr. Gr. van Dam. This form is at once distinguished from the type 
of the species (Records Albany Museum II, p. 412) in the complete 
absence of spinules on the coxa of the second leg : the inferior surface 
of that coxa is largely covered by stiffish setae. The coxa of the third 
leg has a patch of stout spinules extending along the whole length of 
the segment posteroventrally : these spinules are stouter than, but 
not so numerous as, those in the type of the species. There are also 
minor differences in the ocular arrangement : the cleft between the 
frontal eyes is decidedly deeper in this new variety than in the types, 
and the distance between the posterior median eyes is about If times 
that between the posterior median and posterior lateral eyes, whereas 
in the type the proportion is scarcely as much as 1J times. Viewed
