vertical one beneath their fore extremity (from which there issues 

 also a strong, black, curved, spine-like apophysis directed forwards) ; 

 and their hinder portion extends far backwards in a pointed form at 

 the extremity, beneath the radial and the fore part of the cubital 

 joints. 



A single adult male found on low plants on the plains of the 

 Jordan. 



Salticus dentatidens, sp. nov. 



Male adult, length 2 lines. 



This species is closely allied to S. mordax (antea, p. 344), but the 

 white spots and fore marginal bar on the abdomen are far less marked. 

 The humeral joint of the palpus has a tooth-like prominence beneath 

 its base ; and the apophysis near its fore extremity springs more from 

 the side and projects more outwards than in that species ; it is also 

 stronger, rather more curved and more distinctly bifid at its extremity, 

 owing to a decided, though small, prominent tooth-like projection on 

 its inner side near the extreme point : like S. mordax, the radial joint 

 has its outer extremity produced ; but the apophysis is rather smaller 

 and less obtusely pointed. The digital joint and palpal organs are 

 very similar to those of the species mentioned. 



Examples of this species (which M. Simon considers to be a very 

 distinct one) were found on the plains of the Jordan, on the road 

 between Jerusalem and Nazareth, on Mount Carmel, and near Da- 

 mascus. 



Salticus furcatus, sp. nov. 



Male adult, length 2 lines. 



This Spider is entirely black, except that the cephalothorax has a 

 narrow marginal border of white hairs, and on the abdomen is a faint 

 representation of the fore-marginal border of similar hairs (character- 

 istics of many species of this group) ; the tarsi and metatarsi of the 

 legs are brownish yellow. The characteristic apophysis from beneath 

 the fore extremity of the humeral joint of the palpus is very distinctly 

 bifid in a furcate form, the hinder limb of the furcation being rather 

 the shortest, straightest, and least strong ; the radial joint has a rather 

 slender, sharp-pointed, hooked, black spine projecting outwards from 

 beneath ; the palpal organs extend backwards and inwards in a very 

 strong and obtusely prominent form, and they have also, beneath 

 their hinder extremity, a curved, corneous prominent, blunt-pointed 

 projection : there is also a small conical tooth-like prominence beneath 

 the hinder extremity of the humeral joint. 



It is possible that the abdomen of this Spider may have been acci- 

 dentally denuded of the white hairs which in many species form the 

 characteristic spots. It is evidently nearly allied to Heliophanus 

 melinus (L. Koch), of which the adult male is unknown to me ; but 

 M. Simon is of opinion that it is distinct. 



A single example was met with on low plants at the village of 

 Nain.
