smaller ones. Metatarsus II similar, but with the spines weaker and 

 more irregular ; both are unscopulated, but metatarsus II has a few 

 scattered hairs on under surface distally. Metatarsus III spineless 

 but bearing stiff setae and a small patch of scopular hairs distaljy ; 

 metatarsus IV with neither spines nor setae, slightly swollen distally, 

 tapering towards base and curving upwards ; under surface entii'ely 

 and densely scopulated, save for small tapering basal portion. 



Peilipalps hardly distinguishable from M. terricola. 



Measurements. Chelicerae to end of abdomen, nearly 12 mm. 

 Carapace G mm. long, 5'7 mm. wide. 1st leg 15'5, 4th leg 16'5 mm. 

 long. 



A^(No. 7813) from Brandvlei, Wore., appears referable to this 

 species ; it differs from the Houwhoek <$ in that the legs are uni- 

 colorous and longer relatively to the carapace, the latter being identical 

 in measurements with M. peringueyi ; eyes, palp, scopulation, and 

 metatarsus IV" are the same ; the spinatiou is slightly stronger, and 

 cephalic portion of carapace smoother and more reticulated than in 

 peringueyi. 



Nine-? ? audjv. (No. B1555-6) from Beaufort West are practically 

 identical in appearance and characters with the Matjesfontein speci- 

 mens, and there is no doubt that the species extends also to the above 

 locality. 



MOGGRIDGEA LATUS, II. Sp. 



Specimens. Nine ? ? (types) and 32 jv. (No. 150,082), taken by 

 Dr. W. F. Purcell from an old mud wall at Caledon ; 7/10. 



This species is very closely allied to M. peringueiji, and with the 

 advent of the male it may prove to be a very distinct local variety; 

 the main distinction being in the ocular area and in general size. 



Colour. Carapace and legs infuscated brown ; abdomen dark 

 purplish black above in adults, and testaceous below; the upper 

 surface bearing traces of testaceous spots and markings. In younger 

 specimens (seen in spirits) the abdomen has distinct testaceous 

 markings bringing out oblique lines down the abdomen ; the anterior, 

 darker half of the abdomen usually has 4 testaceous spots forming a 

 square, and a continuation of light spots down each side ; in some, 

 black oblique infuscations on a light surface make the principal 

 pattern, and in others the testaceous spots, somewhat elongated, on 

 a dark ground. 



Carapace. General proportions much as in peringueyi, i. e., width 

 nearly equal to length, and length equal to patella, tibia, and 1 

 metatarsus of 1st leg, and subequal to tibia and metatarsus of 4th
