In one the upperside of the abdomen is entirely black ; in a 

 second it is also black with a bright yellow transverse stripe 

 crossing it from shoulder to shoulder ; in the third, which seems 

 to be less prevalent than the others, the whole of the upperside 

 behind the anterior shoulders is yellow.

Cyrtopliora larinioides, Simon, Ann. Soc Ent. France, 1894, 

 p. 155. 



Loc. Benito Eiver {G. L. Bates). 

 Described from Ogowe. 



Cybtophoea mabgaeitata, sp. n. (Plate LV. figs. 4, 4 a.) 



Colour almost as in C. unicolor Do!., a tolerably uniform 

 yeUowish brown ; the abdomen darker than the carapace and 

 limbs, legs indistinctly variegated, sternum and lower side of 

 abdomen blackish. 



Carapace smooth as in C.citricola; eyes as in the latter species, 

 but the laterals closer together. 



Legs as in C. citncola, but with tarsi and protarsi shorter ; tarsus 

 and protarsus of 1st, for example, being distinctly shorter than 

 patella and tibia of 1st. 



Abdomen truncate in front, narrowly ovate behind, not lobate 

 laterally, and only weakly bilobate posteriorly, as in C. angoletisis ; 

 studded above with larger and smaller smooth circular bosses, very 

 like those of C unicolor, but much larger and less numerous. 



Vidva as in figure (PL LV. fig. 4 a). 



Measurements in millimetres of type. — Total length 14 ; length of 

 carapace 6-5, of abdomen 9, width of abdomen 7*5 ; length of 1st 

 leg 19, its patella and tibia 7, protarsus and tarsus 6. 



Loc. Benito Eiver {G. L. Bates). 



At once recognizable from C. unicolor by the strong curvature 

 of the posterior line of eyes, narrow interval between the lateral 

 eyes, absence of tubercles on the carapace, large size of tubercles 

 on the abdomen, &c. From the rest of tbe W.-African species 

 known to me it may be at once recognized by the features 

 mentioned in the subjoined table. 



The four W.-African species of Cyrtophora known to me may 

 be distinguished as follows : — 



a. Abdomen long and narrow, produced in front into a 



longish process overhanging the base of the cara- 

 pace larinioides Sim. 



b. Abdomen truncate in front, broadest at its anterior end. 

 a^. Abdomen without distinct shoulder prominences and 



no lateral prominences ; its upperside studded 



with large circular tubercles margaritata, sp. n. 



b^. Abdomen with distinct shoulder prominences and 

 one or more prominences on each side ; upper- 

 side studded with smaller tubercles. 

 or. Abdomen with one prominence on each side 

 behind the shoulder, posteriorly deeply bifid ;
