13. Lateral wall of flagellum furnished along its middle with a thick 
pale yellow longitudinal rib, extending throughout the whole length: surface 
of flagellum thickly studded with prickles right up to the apex. Distal dorsal 
bristle becoming gradually thinner towards the apex, and covered with very 
minute spinules in its distal part. Third tooth of upper jaw rudimentary. 
B. namaquensis Purcell. 
14. Third tooth of upper jaw only a little smaller than the first or the 
second. Distal dorsal bristle precisely similar to the other bristles which 
occur on the upper and outer surfaces of the chelicerae, and with only a trace 
of short fine setose prickles on its distal portion. Surface of flagellum closely 
studded with minute triangular denticles except towards the base, and on 
the narrowed distal portion. B. laminicornis Hewitt. 
E. Flagellum long, reaching beyond the tip of the fang when 
directed forwards; not very broad in any part, nor greatly attenuated 
either towards the apex or the base ; the cavity of the slightly expanded 
capsule, which occupies the distal portion of the basal half of the 
flagellum, has a short oval aperture: the lancet-shaped distal half of the 
flagellum is lightly curved, and the membrane bordering it along the 
upper or anterior margin is very finely serrated from the capsule almost 
up to the apex. B. fimbriata Kraepelin.^ 
Genus Gluviopsis Kraepelin. 
Gluviopsis australis Purcell, 1901. Annals S. Af. Mus. n. p. 219, fig. 8. 
The type came from Styrkraal near the Orange River in the Kenhardt div. 
This is the only species described from S. Africa, but Kraepelin gives some 
notes on a female example of the genus from Swakopmund. 
The flagellum of australis — which is only known to me through the descrip- 
tion and figure — is more or less oblong in shape, tapering towards the base, 
strongly compressed and bent outwards distally, the apex being very broadly 
subtruncated and lacerated. There are four large teeth in the single series of 
the upper jaw. 
Genus Hemiblossia Kraepelin. 
Hemiblossia bouvieri Kraepelin, 1899. Das Tierreich, p. 104, fig. 77. 
This is based on a single female specimen from the upper Zambesi. 
Hemiblossia O’neili Purcell [Pis. Ill, fig. 5 and VIII, fig. 42], 1901. Annals S. Af. 
Mus. 11. p. 217, figs. 6 and 7. 
This is based on several males and females from Dunbrody on the Sundays 
River. Also known to me from Alicedale (F. Cruden), De Aar (S. C. Cronwright- 
Schreiner) and Kimberley (Bro. J. H. Power). A figure of the flagellum of 
Alicedale specimens is given by me in Records Albany Mus. vol. 111. p. 12. 
The inner surface of the chelicera in both sexes has stridulatory ridges, simple 
bristles, and feathered bristles, as usual.
