86 Mr. F. 0. P. Cambridge on Cteniform Spiders 



narrower in front. Clypeus eqr.al to 1| diameter of anterior 

 centrals. Apex of inner marginal spine of palpal organs 

 simple, blunt, and stout. 



A single male was taken by IMr. Eamage near Iguarassu, 

 Brazil. The species is closely allied to others of the " cur- 

 vipes " group whose posterior 2)rota7-si are straight. (PL III. 

 figs. vi. a and vii. b.) 



Cfenus spiculusj sp. n., ^ . 



Hah. Colombia. 



Type in coll. Brit. Mus. Nat. Hist. London. 



Tot. len. 15'D mm.; carap. 9; pat. + tib. i. 1Q75, iv. 16, 

 iii. 9-75. 



Colour. Carapace brown, cephalic area with two pale lines 

 on each side, followed by a central line to posterior margin. 

 Legs and abdomen brown (dried specimen). 



Structure. General characters as in others of the group. 

 Carapace gibbous at base above. Ocular quadrangle broader 

 than long, narrower in front. Second row straight by ante- 

 rior margins; clypeus equal to H diameter of anterior 

 centrals. Carapace less than pat. and tib. iii. 



Protarsus iv. slightly sinuous, basal concavity (very slight) 

 directed outwards. Apical concavity directed inwards, more 

 noticeable, not spinose except at apex, and from basal end of 

 apical section towards the base of the segment armed with 

 numerous spines. This form of protarsus iv. forms an inter- 

 mediate link between rectipes, nigritus, and longipeSj and 

 plan{})es^ serratipes^ (fcc. 



I'ibiai s))Ur longer, more slender, twice as long as its basal 

 breadtl), apex carinate, recurved ; directed straight forwards. 

 Marginal spine of palpal organs stout at apex and simple. 

 Central lobe short, dorsally excavate, not emarginate or bitid 

 in front. 



A single specimen of this distinct form taken in Colombia 

 is in the Museum collection. (PI. IIL fig. vii. h.) 



Ctenus minimus J sp. n., (^ . 



Hah, N. America. 



Type in coll. Brit. Mus. Nat. Hist. London. 



Tot. len. 7*5 mm., carap. 3'75 ; legs i. 17, iv. 16. 



Structure. Carajiace raised and gibbous behind. Tibiae i. 

 and ii. with five pairs of s[)ines beneath and two lateral spines 

 on each side. General structure otherwise similar to others 

 of the group. Protarsus iv. straight. Pedipalp long, at least 

 two thirds that of carapace, 6 mm. Patella tliree times longer 

 than broad, tibia four times ; tibia iucrassate towards apex (as
