234 W - F - PURCELL, 32 
Inferior Spinners short, the length of the basal segment subequal to or even a little less than the 
width of the ocular area. 
Length of cephalothorax + abdomen 7V2 mm - 
4. Theuma fusca Purc. 
L907, Pürcell, Ann. Mag. Nat. Hist., Ser. 7, Vol. XX, p. 300 ($? and o'o' from Robertson and Cape Divisions, 
Cape Colony). 
Specimens. 1 rf, 4 $? and I juv. from Southern Hereroland (S and juv. from Otjimbingwe), 
September and October 1903. 
The females agree in their characters with the Cape Colony form', excepting that the posterior median 
eyes are slightly closer together than is usually the case in the types. The male differs slightly in the 
position of the free portion of the Stylus, which arises opposite to the origin of the coiled tube, whereas in 
the specimens from Cape Colony the free portion of the Stylus arises on the same side as the origin of the 
coiled tube. As the females do not otherwise appear to differ in any essential point, I do not venture to 
make a distinct species on this character alone, and, moreover, I have noticed exactly the same Variation 
in the position of the free portion of the Stylus among the males of T. capensis Purc. from the Cape 
Peninsula. 
5. Theuma schnitzet n. sp. 
Specimens. a) 2 ?? and 4 juv. from Steinkopf, Little Namaqualand, July and August 1904. 
Very similar to T. fusca Purc. (Ann. Mag. Nat. Hist., Ser. 7, Vol. XX, p. 300, 1907), but differing 
in the following characters : 
Posterior row of eyes wider, with the eyes further apart, the medians almost or quite 2 diameters 
from the laterals and distinctly much further from them than from the anterior lateral eyes. (The posterior 
median eyes small, distinctly smaller than the anterior lateral eyes.) 
Legs. Metatarsus I with 2 subbasal spines only (1 on each side below). Tibia I with 4 pairs 
of inferior spines (including an apical pair) but with none on the lateral surfaces. 
Inferior Spinners (in adult) considerably smaller, their length scarcely or not at all exceeding 
the width of the posterior row of eyes. 
Length of cephalothorax -f- abdomen 8 mm. 
b) 19 juv. from Kammaggas, Little Namaqualand, July and August 1904. 
c) 3 subadult specimens from Lüderitz Bay, Great Namaqualand, January and February 1904, prob- 
ably belonging to this species. 
lt is noticeable that in the immature examples the Spinners are longer relatively to the width of the 
ocular area than in the adult. 
6. Theuma maculata Purc. 
1907, Purcell, Ann. Mag. Nat. Hist., Ser. 7, Vol. XX, p. 302 (?? and J from Beaufort West, Cape Colony). 
Specimens. a) 1 ?, 2 S<3 and 22 juv. from Kamaggas, Little Namaqualand, July and August 1904. 
b) 24 juv. from Steinkopf, Little Namaqualand, July and August 1904. 
Dr. Schultze also collected 3 young specimens (no. 525) of Theuma from Kubub, Great Namaqua- 
land, and 1 from Steinkopf, Little Namaqualand, which I have not been able to determine.
