line joining the lower borders of the anterior medians. Anterior 

 laterals slightly more than 3 times the posterior medians' diameter 

 from the latter. Ocular area barely 3 times as wide as long. 



Sternum. Less than twice as long as wide. 



Legs. Metatarsus IV with 4-5 moderately long fine spines apically 

 on the under surface ; legs otherwise spineless. 



Vulva. As in figure. 



Measurements. Length of carapace 4'5 mm. ; breadth 4 mm. (ratio 

 of length to width 1'2 : 1). Total length 16 mm. 



DRESSERUS KANNEMEYERI, n. sp. (Plate XXIX, figs. 5 A-C and 7 c). 



Specimens. I (No. B 27) and 3 ? ? (No. B 242), Types ; and 

 4 9 $ (No. 14612) from Smithfield, O.F.S. (Dr. D. B. Kannemeyer, 

 12/09). 



. Colour. Carapace very dark, black-red ; clothed with short, 

 appressed, dull white hairs over entire surface (save for posterior 

 border), and with long olivaceous black hairs at sides and posterior 

 border of cephalic portion, and to a less extent anteriorly. Chelicera 

 reddish-black, darker anteriorly, and clothed with long olive-black 

 hairs. Abdomen dull testaceous, clothed with moderately long olive- 

 black hairs and short sparse white ones, thus giving a slightly mottled 

 appearance, and with 4-5 broad arrow-head markings dorsally pos- 

 terior to sigilla ; under surface iufuscated around and above spinners 

 and cribelluui. Legs reddish-brown and slightly infuscated ; meta- 

 tarsi lighter and redder, especially metatarsus I ; tarsi darker. Hairs 

 on legs dark olivaceous in colour. Sternum, labium and coxae of 

 pedipalps reddish-brown in colour ; coxae of legs olivaceous brown. 



Carapace. Surface finely reticulate. Equal in length to patella, 

 tibia and f metatarsus, and slightly less than tibia, metatarsus and 

 tarsus of 1st leg. Width equal to or slightly exceeding tibia and meta- 

 tarsus, and equal to patella, tibia and i metatarsus of 1st leg ; it also 

 exceeds the distance from, fovea to front of ocular tubercle by f or 

 more of the length of the tubercle. Seen from above, the carapace 

 does not appreciably narrow anteriorly, although the widest portion is, 

 as in D. restrains (Pure.), behind the posterior lateral eyes. Cephalic 

 portion is also very flat and slopes slightly from posterior border to 

 anterior, i. e. highest portion posteriorly (see fig. 7 c). Ocular 

 projections as in rostratus, armatus and subarmatus ; base of each 

 anterior lateral tubercle stretches as a faint blunt ridge to posterior 

 lateral eyes. 



Eyes. Posterior medians about 2 diameters apart and 4-5 times as 

 large as the anterior medians. Posterior laterals wider apart than
