68 Rev. O. P. Cambridge on new Species of Araneidea. 



taining a double curve ; central part thinner and weaker than 

 the portion on either side ; extremities pointed and curved ; 

 behind this curved point a portion of the face of the fang is 

 bluntly serrate. Colour of both falces and fangs (excepting 

 the extremities of the latter and base of the former, which are 

 rather lighter-coloured) dark black-brown and shining ; inner 

 face of the falces slightly wrinkled in a transverse direction ; 

 two rows of minute teeth beneath the falces, and several larger 

 ones near the insertion of the fangs. 



Abdomen joined to cephalothorax by a short cylindrical 

 pedicle ; oval in form, rather pointed in front, truncate behind. 

 Colour glossy black. 



A single specimen of this species in the Hope Collection, 

 Oxford, captured in Ceylon by Mr. G. H. K. Thwaites. It is 

 closely allied to Salticus manducator (Westwood) (described 

 and figured in Gue'r. Mag. de Zool. 1841, Arachnides), but 

 differs from that species in the falces and fangs : the former 

 are rather larger in 8. bicurvatus, and the latter have a double 

 curve (as above described). The denticulation beneath the 

 falces also differs in the two species. 



Salticus plataleoides, n. sp. 



<$ . Adult. Length, to extremity of falces, 6 lines, to in- 

 sertion of ditto 3^ lines. 



The entire spider is of a dull brownish-yellow colour, except- 

 ing the tips of the falces, which are black on the outer sides, and 

 the upperside of the caput, which is of a bright rufous colour. 

 The basal half of the falces has an opaline lustre in different 

 lights, and their extremities have a rufous hue. 



The cephalothorax is similar in form to that of S. bicurvatus', 

 but the caput is more of an oblong shape. Eyes of second row 

 nearer to those of first row than in S. bicurvatus, i. e. about 

 one-third of the distance between the first and third rows ; and 

 they are inside of the straight lines between the exterior eyes 

 of these rows. 



Legs long, slender ; extremities of tibia? and tarsi sparingly 

 furnished with hairs ; their relative length was apparently 

 4, 1, 3, 2. The pedicle joining the abdomen to the cephalo- 

 thorax biarticulate, and as long as the thorax. 



Falces of great length, projecting in nearly the same plane 

 as the cephalothorax ; basal half very slightly and transversely 

 rugulose, and shining in some lights with an opaline hue, flat 

 on their inner face ; extremities much and abruptly enlarged 

 on upper and outer sides for about one-third of their length, 

 giving to the spider (when the falces are close together) much 

 the appearance of the Spoonbill {PJatalea leucorodid). The
