adds another to the numerous generic, or subgeneric, forms of the 

 genus Saltims, Latreille. It has a close affinity to Lyssomanes, 

 Hentz ; but its differences from that, as well as from anoiher allied 

 genus, Jelskia, Tacz., appear to me to warrant its beino- made the 

 tjpe of a separate group. °

It is with great hesitation that I include the present West- 

 African Spider in the genus Cyrtarachne, differing, as it does, from 

 the typical species in the greater length and slenderness of the first 

 and second pairs of legs, as well as in the higher eve-eminences. The 

 form, however, of the maxillae and labium is similar ; and as the 

 three long and remarkable spines ou the cephalothorax are repre- 

 sented m some (if not in all) of the typical Australian species of 

 Cyrtarachne, I have thought it best to place it provisionally with 

 tliem until perhaps other species from West Africa may prove it to 

 belong to a group specially characterized by the peculiarities noted, 

 and so to require a separate genus for their reception. 



The cephalothorax of this Spider is broad and rounded behind, 

 much narrower in front, and strongly constricted laterally at the 

 caput. The occipital region is gibbous and has three long, strono- 

 pointed, tapering, nearly erect spines in a line along the middl?' 

 Ihese spines are almost straight, but rather divergent ; the central 

 one IS the longest, and the anterior the shortest. Its colour is yellow 

 strongly tinged with brownish orange on the caput, and covered with 

 a fine, silky, whitish pubescence. The three spines are also similarly 

 clothed ; and their basal portion is similar to the caput in colour 

 their upper part being of a deep blackish red-brown. ' 



The eyes are very small, and of an amber-colour ; they are seated 

 on three strong, somewhat tuberculiform eminences placed in a 

 transverse line at the fore part of the caput. The central eminence 

 (which is much the largest and highest) has four eyes near its sum- 

 mit, in the form of a quadrangle, whose transverse is rather longer 

 than its longitudinal diameter ; the two posterior eves of these four 

 are the largest of the eight. The eyes of each lateral pair are placed 

 contiguous to each other near the upper extremity, on the outer 

 sides of the lateral eminences. 



The %5 are rather slender, and differ considerably in length- 

 those of the first pair are much the longest ; next to them are those 

 of the second pair ; and the third pair are a good deal the shortest 

 Ihey are of a dull yellow colour, the femora tinged with orange, and 

 (excepting these joints) unequally annulated with dull reddish brown- 

 they are also furnished with numerous long, prominent, fine, silky' 

 whitish hairs, but no spines ; and each tarsus terminates with three 

 rather sharply bent claws, the two superior ones pectinated at their 

 base. The tibiae are gradually enlarged at their anterior extremities
