1898.] CTENirOEM SPIDEES OF AFEICA, AKABIA, AND SYEIA. 21 



CTETnjs JOHNSTONi, sp. 11. (Plate III. lig, 7.) 



2 . 37-8. Hah. Zomba, Lake Nyassa, B. Africa. Type in coll, 

 Brit. Mus. Nat. Hist. London. 



Total length 37'8. Carap. 18 x 14. Anter. marg. 8. Prot. 

 i. 13— iv. 16-25. 



Colour. Mandibles with basal balf clothed with thick rut'ous- 

 grey pubesceoce. Abdomen clothed entirely with rufous pubes- 

 cence, ochre-yell o\\' on legs. There would be nothing, save in 

 the difference in the eye-formula, to distinguish this form from 

 the male from the Cameroons. The colour of the mandibles is 

 identical. There is present in this female the basal inner and outer 

 spine on the anterior tibiae as well as the single small spine at 

 apex of protarsi i. and ii. beneath. 



Vulva. See Plate III. fig. 7. 



The eye-formula is similar to that of the male mentioned above, 

 except that the laterals of the second row are higher and the 

 lateral posteriors further from centrals. 



"Whether this difference is more than sexual, I have not 

 sufficient material on which to base a definite decision, but I 

 should suspect not. 



Three females from E. Africa, two being from Lake Nyassa, 

 Zomba, were found in the Museum collection, presented by 

 Sir Harry Johnston. 



Ctenus kingsleyi, sp. n. (Plate III. fig. 6.) 



5. 30 mm. Hah. Cameroons; coll. Kingsley. Type in coll. 

 Brit. Mus. Nat. Hist. London. 



5 . Carap. 1475 x 11. Legs 4, 1, 2, 3— i. 60'5— ii. 56— iii. 48— 

 iv. 63. Pat.-l-tib. i. 21. Pat. + tib. iii. 15-5. Pat.+tib. iv. 19. 

 Prot. i. 13, iv. 17-5. 



2 . Colour. Carapace mahogany-brown, clothed M'ith short 

 grey pubescence. Mandibles entirely black, clothed with short 

 black hairs, rufous on inner apical margin. Legs clothed with 

 short black and grey hairs and rufous-yellow pubescence. Abdo- 

 men unicolorous warm brown, with indistinct deiitate dorsal 

 longitudinal pattern, with narrow central dark band beneath 

 bordered with a white line. The face bears a narrow band of 

 rufous pubescence on each side of the ocular area. 



Structure. Carapace horizontal, slightly gibbous behind, slightly 

 inclined to base. 



Eyes. Second row straight. Line ])assing through centres of 

 posterior centi-als cutting posterior margins of laterals. Diameters 

 of centrals nearly 4 times the transverse diameters of laterals, § a 

 diameter apart, | a diameter from laterals. Posterior laterals 5 

 smaller (by diameters) than centrals, 1| diameters from the latter. 

 Ocular quadrangle broader than long, narrower in front ; posteriors 

 5 larger ; anteriors | a diameter apart, the same from posteriors. 

 Cli/peus two full diameters of anterior central eye. Lower margin 

 of fang-groove with four stout teeth, upper with three. 



Simulation of legs. Similar to the male of C. carsoni, but with
