species). — The description of C. amahiritha in H. N. d. Ins. Apt., 

 1, p. 591, contains nothing that excludes the possibility of that spe- 

 cies being the same with C. pallidula; but in Faunc Franc, , Arachn., 

 where the descriptions are far more detailed, Walckenaer says p. 

 llfi, concerning the males of C. hoheericea and amarantha! "Dans 

 la soyeuse [C. holosericea'] les mandibules du male ne different guere 

 de celles de la femelle, elles sont settlement un pen main.? fortes; 

 dans l'amaranthe [C. amarantha] elles sont tellemmt allongha quelle* 

 e</ah'nt la longueur du corselet: elles sont aussi plus minces et diri- 

 ge'es en avant, et presque comme l'atte formicoide". Hence it seems 

 to me to follow, that C. amarantha Walck. is not the same as C. 

 pallidula, although the length stated ("5 lignes" = ll 2 / 5 milliin.) 

 seems most immediately to indicate that as the intended species; I 

 am more inclined to refer it to C. holosericea Westk., which some- 

 times, though not frequently, attains that size, and the mandibles 

 of which are sometimes more than 3 /. of the length of the cephalo- 

 thorax. The species again which Blackwall looks upon as Walcke- 

 naer's C. amarantha, is a far smaller spider, described by Westking 

 under the name of C. terrestris; of which more hereafter. Hahn's 

 C. amarantha on the other hand is certainly identical with C. palli- 

 dula; perhaps his C. holosericea, which is "5 '/ 3 line" long (loc. cit., I, 

 p. 112, Taf. XXIX, fig. 84) and has a black side-border on its ce- 

 phalothorax, as well as C. amarantha Ohlert, may be the paler va- 

 riety (Var. a Westr.) of the same species. 



C. e.pime.las Walck. , of which Walckenaer seems only to have 

 seen one specimen , a ?, certainly belongs to the darker variety (Var. 

 b Westr.) of C. pallidula. Of this variety I have not only females, 

 but also cf ad — C. epimelas Blackw. is a sure synonym, although 

 Bi.ackwali/s description of the male's palpi is not quite correct. Of 

 this species Cambridge has had the kindness to send me a cf ad. 

 Blackwall's figures show that his C. epimelas refers especially to 

 individuals of the darker variety (Var b Westr.). 



I should have considered Blackwall's figure of C. formosa as 

 singularly excellent, if it had been said to represent a $ of C. pal- 

 lidula Var. a, after oviposition. Blackwall has probably not seen 

 the type-specimen of C. formosa, but only Templeton's figure and 

 description of it. 



C. incomta C. Koch probably belongs , as is generally supposed , 

 to this species. C. incomta Ohl. on the contrary, of which Ohlert 

 has obligingly sent me a ? ad., and which has the cephalothorax
