the base, moveable and articulated to the tarsus; sometimes two or even 
- three such spines are found situated close to each other at the extremity of 
the palpus. In Dolomedes (at least D. fimbriatus), the palpus of the male 
(as has been discovered by OmnLERT, loe. cit.) is provided with a genuine 
pectinated claw at its extremity, which is not the case in any other genus 
that I know of among the Citigradæ (not even in Ocyale), and has only 
been observed in one spider beside Dolomedes, namely in Æersiliola oraniensis 
(Conf. p. 116). 
The European genera accepted by us as belonging to this family 
are as follows:

* Oculi medii seriei anticæ a margine clypei spatio remoti quod diametrum 
oculorum non vel paullo tantum superat.
