New Arachnida. 25 



2 smallest specimens, in which the lids are almost cylindrical and 

 quite cork-like. But the principal feature of these lids is the 

 presence of a number of very conspicuous, large pits, arranged in a 

 circle and situated half-way between the centre and the circumference 

 of the lower surface. These pits may be open, or partly filled up, or 

 spun over with some strands of siik, being, however, still visible as 

 dark spots. Sometimes the portion of the circle nearest the hinge is 

 obliterated. 



GOKGYBELLA SCHREINERI, n. Sp. 



(PI. I., figs 3-4.) 



Types. 35 specimens (No. 9518, &c.), mostly adult females from 

 Hanover, and 5 from the neighbouring farms Vlagkop and Poort- 

 jesfontein. Adult ? 5 from September to January. Cocoons in 

 December. Young in January. 



5 5 . Colour like that of G. namaqiiensis, Pure. (Trans. S.A. Phil. 

 Soc., v. 11, p. 350) or darker ; the carapace and limbs pale ochraceous, 

 often faintly infuscated ; chelicerae yellowish brown to darker brown ; 

 abdomen wholly pale yellowish to dirty ochraceous, the dorsal 

 surface sometimes darkened with purplish brown ; sternum and 

 coxae pale yellow to ochraceous ; labium and eoxse of pedipalps 

 slightly darker ochraceous to light brown. 



Carapace (measured laterally to the ocular area) as long as the 

 tibia, metatasus, and ^-^ of the tarsus of fourth leg and as the patella, 

 tibia, and -J-f- of the metatarsus of first leg. Ocular area wider than 

 in namaquensis, its width equalling or exceeding the length of the 

 metatarsus of first leg (by about ^ of the tarsus), its length also 

 generally much less than the distance between the lateral eyes. 

 The area formed by the anterior lateral (frontal) and anterior 

 median eyes parallel-sided or wider in front (rarely very slightly 

 wider behind), the median eyes f -1^ times their diameter apart, the 

 frontal eyes subequal to or considerably larger than the medians and 

 |-1 diameter apart. Posterior median eyes generally distinctly 

 further from the posterior laterals than from one another (sometimes 

 only as far) ; the area formed by the 4 median eyes very distinctly 

 wider behind than in front ; posterior lateral eyes large, their distance 

 from the anterior margin of carapace less than ^ the width of the 

 ocular area. 



Pedipalps and legs as in namaquensis, except that the tibia of the 

 fourth leg is provided with 3-10 (rarely 0-2) short spinules along the 

 outer surface, at least at the base ; the metatarsus of the third leg 

 with 2 (sometimes 3) distal spines (rarely spiniforrn setas) below ;
