New Arachnid a. 31 



10048). Also about 90 young from Hanover (33 in October, 

 $ in October, November, and January). 



Closely agrees with the description given of H. namaquensis, Pure. 

 (Trans. S. A. Phil. Soc., v. 11, p. 324), and apparently differing only 

 in the following characters : 



Carapace with a considerable number of dark olivaceous or olive- 

 black hairs between the pale golden bands, and also on the cephalic 

 area behind and at the sides. Posterior lateral eyes elongate, 

 generally considerably longer than the posterior median eyes. 



Palpal organ, when seen from the side (pi. I., fig. 9), with the 

 process stouter at the base and becoming very regularly thinner from 

 the base to the apex, more quickly in the proximal part, but very 

 gradually in the distal half, its strongest curvature appearing at the 

 middle, while the distal part is straighter and very fine (seen from 

 the front the distal part appears strongly curved outwards). 



Measurements of large $ and ? from Hanover. Total length 

 $ 40, ? 51 ; length of carapace $ 16, $ 19^, of metatarsus of first 

 leg $ 12i, 2 91 



In namaquensis (pi. I., fig. 8) the proximal f or 4 of the process 

 (when seen from the side) appears stout, only very slightly curved 

 and becoming very gradually thinner, then tapering suddenly and 

 passing into the fine, somewhat bristle- like, distal fourth or fifth, the 

 strongest curvature appearing at the point where the bristle-like part 

 commences (seen from the front the process appears slightly out- 

 curved at the apex only). The posterior median eyes, also, are 

 generally almost or quite as large as the posterior laterals. 



H. baviana is found under stones, generally in shallow excavations, 

 but sometimes also in burrows a few inches deep. It is a very 

 common species, although adults were rarely met with. 



FAMILY 



GEN. SEOTHYEA, nov. gen. 



Cephalic portion of carapace very high, strongly rounded posteriorly, 

 rounded also at the anterior lateral corners and just as long as wide, 

 its upper surface strongly and evenly convex from in front to behind 

 in the $ (being highest in the centre) but somewhat flattened with 

 the highest part behind in the adult $ . All the eyes small and 

 equal, the median eyes in 2 rows and close together ; the area 

 formed by the lateral eyes scarcely, if at all, narrower behind than 

 in front, less than twice as wide as long. Clypeus considerably
