II Araneae. 2i? 
Although it is not possible to establish with certainty the identity of immature specimens like the 
two last, there can be little doubt but that these belong to this species. 
The young specimens from Steinkopf and Kammaggas so closely resemble the females and young of 
the two species of Harpactirella described above and found in the same localities, that they are distinguishable 
with certainty only by means of the setae on the sides of the chelicera, as already explained in Trans. S. 
Afr. Phil. Soc, Vol. XI, p. 341, 1902. 
Genus Ceratogyrus Poe. 
Ceratogyrus schultzei n. sp. 
4 ?$ from Kgokong to Kang, Kalahari, Bechuanaland Protectorate, December 1904. 
Colour brown, the abdomen sometimes nearly black. Hairs covering cephalothorax silky, pale- 
greyish, often tinged with yellowish, those alongside and in front of the ocular tubercle and on the foveal 
hörn olivaeeous, those on the ocular tubercle of a deeper yellow; short hairs on the legs for the most part 
greyish, the long hairs pale-foxy; hair-covering on abdomen grey or pale brownish- yellow, forming 
numerous pale spots on the dark skin, the longer hairs often pale-foxy; underside of abdomen clothed with 
pale salmon-tinted hairs on the segment bearing the anterior pair of lungs, except quite anteriorly, where 
the hairs are black, the rest of the abdomen, including the second pair of lungs, clothed with black hairs 
below; coxae, sternum, and innerside of pedipalps and of 2 anterior pairs of legs clothed with black hairs; 
chelicera clothed with pale-greyish hairs, which are often slightly foxy. 
Cephalothorax subequal to (only very slightly longer or shorter than) the metatarsus and tarsus 
of fourth leg, but longer than the tibia and metatarsus of first leg (from very slightly to 74 longer). Foveal 
hörn very large and long, becoming very gradually and slightly narrower towards the apex, which is rounded 
and very obtuse; its length along the upperside about i 1 /, times its width at the base; seen from the side 
the hörn appears inclined backwards at about half a right angle to the horizontal, its anterior (or Upper) 
edge appearing feebly convex, its posterior edge feebly coneave or almost straight and standing up some 
distance off from the surface of the cephalothorax. 
Legs. Tibia of first leg 3 — 3V0 times as long as high in the middle, its length exceeding that 
of the metatarsus (by up to l / 6 of the tarsus) and equal to the distance from the fovea to some point be- 
tween the anterior margin of the ocular tubercle and that of the cephalothorax and also subequal to or 
slightly less than the length of the fourth tibia. 
Apical segment of posterior Spinners much longer than the penultimate segment and than the 
ocular tubercle. 
Total length (including chelicera) of a ? 40 mm ; length of cephalothorax 16 1 /., mm, width £3% mm ; 
length of foveal hörn 6 mm, width at base 4 mm, height of highest part above the thorax 3 2 / 3 mm ; distance 
of fovea from anterior margin of cephalothorax 9 mm ; length of tibia of first leg 8 mm, of metatarsus 7 mm. 
These females are certainly speeifieally distinet from C. darlingi Poe. (Proc. Zool. Soc. London, 1897, 
p. 754), the only other species of which the females have been described. In the latter the foveal hörn is 
much more conical and tapering and more erect, and the second pair of lung-opercula is pale -yellowish 
and not black below. The colouring of C. schultsei n. sp., on the other hand, substantially agrees with that 
of C. bechuanicus Purc. (Trans. S. Afr. Phil. Soc, Vol. XI, p. 339, 1902), also from Bechuanaland, of which 
only the male is known. In the latter, however, the foveal hörn is much more strongly inclined, its posterior 
surface being actually in contact with the thorax, except quite distally, and there is no reason for believing 
that these differences are sexual ones.
