( 305 ) 



terminal fang long and st-rong, the two distal teeth large, strongly laterally com- 

 pressed and sublaminate, appearing l)roadly conical when seen from the side, and 

 placed about midway between the apex and the large basal tooth of the single 

 series ; the latter tooth with a tiny (sometimes obsolete) tooth in front at base ; inner 

 part of dorsal surface deeply grooved, the groove bordered on the inner side by 

 a high keel, the greater or distal part of the groove free, the flagellum occupying 

 only the basal part. 



Lower finger of chelicerae with three upright teeth close together near the base ; 

 the outer side provided in the middle with a strong tubercular crest, as in S. hostilis 

 (White). 



Basal enlargement of flagellum large, rounded above posteriorly, with high 

 dorsal keel ; procurrent portion of flagellum short, recurving 

 between the two distal teeth ; recurrent portion curving 

 slightly and ending just behind the basal enlargement, its 

 upper surface flattened, grooved posteriorly, its apex slender 

 and pointed. 



Pedipalps stout, the three distal segments with numerous 

 truncated cylinder-bristles below. 



? . Upper finger of chelicerae with only one inter- yu:. 2.—Solj>iif/a junoii 

 mediate tooth. First abdominal sternite strongly produced spec. nov. lUght cheii- 

 at the median hinder angles into a pair of broadly rounded ™^''' ° ° '^°™ 

 lobes. Underside of tibia of pedipalps with very few 



truncated bristles, the upperside of this segment, like that of the metatarsus, 

 thickly covered with short, dark brown, cylindrical bristles. 



Total length, S 20 mm., ? 27 mm.; width of carapace, c? 'i mm., ? 64 mm.; 

 length of til)ia of i)edipalp, S 7 mm., ? 51 mm. 



The dentition is jieculiar on account of the absence ol a large gaj) in the single 

 series of the upper finger, although the species is evidently related to S. hogtilis 

 (White), which it resembles in the general coloration, the presence of a mane on the 

 hindlegs and particularly the presence of the strong outer crest on the lower finger 

 of tlie chelicerae. 



Order ARANEAE. 



Amongst the Antneae was one Trapdoor Hjjider of the family Ctcnizidae, eiud 

 belonging to a genus not previously recorded from the Transvaal. This species is 

 described here, but the rest of the spiders have not been identified. 



Heligmomerus cafifer spec. nov. 



1 ? (somewhat damaged). 



('olour of carapace and limbs reddish brown, the underside more yellowish. 



Length of carajiace (measured across jwsterior lateral eyes) e(|ual to that of 

 tiic tibia, metatarsus and two-thirds of the tarsus of fourth leg. Ocular area nearly 

 one-half wider than long, its width considerably less than the length of the first 

 metatarsus ; frontal eyes the largest of the eight, transversely oval, jilaced on 

 sei)arate tubercles and looking slightly outwards and downwards, their distance 

 ujiart about tlirce-(|U:ir(ers oi' their own diameter ; anterior median eyes of the 

 second group mucli smaller than I lie frontal eyes and less than a diameter apart.
