new Spiders from the Camaroons. 2G1 



yellow patch on each side of the posterior slope ; legs rather 

 obscurely banded above, with broad alternating darker' and 

 lighter bands ; npperside of abdomen clothed with short 

 yellowish and olive-brown hairs, forming broad indistinct 

 transverse bands^ with specks of brighter yellow hairs forming 

 a narrow interrupted lateral band; ventral surface uniformly 

 olive-yellow, a slightly darker median ventral band on the 

 abdomen, broader in front and margined with an indistinct 

 narrow pale line. 



Carapace high, flat along the top, a little longer than 

 patella + tibia + tarsus of palp, a little shorter than tibia of 

 third leg and half the length of its tibia -f-protarsus. 



Vulva large, the lateral lobes enclosing a more or less oval 

 space occupied by a large sclerite, triangularly pointed and 

 elevated in front and somewhat sharply constricted behind, 

 where it juts between the extremities of the lateral lobes. 



Measurements in millimetres. — Total length .^1 ; length of 

 carapace 14-5, first leg 64, second Qd, third 59, fourth 71. 



Log. Efulen, in the Camaroons [G. L. Bates). 



The difference in colour between the type of this species 

 and that of I), palpiger is too great to permit the view that 

 they belong to the same species. 



This is the first female example of the genus Dolomedes 

 recorded from tropical Africa. 



Dolomedes Batesii, sp. n. 



? . — Colour. Legs banded as in D. actcBon; carapace without 

 the posterior spots, covered with short greyish-red hairs, 

 mottled, but showing no definite pattern ; darker on the 

 middle dorsal line; middle of cljpeal area occupied by a 

 broad vertical brown stripe, broader below and set off by the 

 pale hairs clothing the sides of the clypeus. 



Apart from colour-differences this species differs from 

 D. actceon in having the eyes of the anterior line recurved by 

 their centres instead of straight, the lower edge of the laterals 

 being on a level with the centres of the medians, and their 

 upper edge rather higher than that of the medians. 



Vulva very large and convex, its central sclerite closino- 

 the space except for a triangular area in front, and almost 

 indistinguishably fused to the lateral portions ; it is roundish 

 in shape, without any anterior angular process, thus differing 

 markedly from that of D. actceon. 



Measurements in nnllimetres. — Total length 23 ; length of 

 carapace 11, first leg 50, second 50, third 45, fourth 57.
