aspect, however, it wants the distinctly reticulated appearance so 

 characteristic of N. reticulatus, and the thorax is marked by some 

 distinct radiating black lines. The legs also are distinctly 

 annulated with black, while those of N. reticulatus scarcely show 

 any signs of annulation. According to M. Simon the male is 

 unknown, but I refrain from giving a more minute description of 

 the one above referred to, as the exact colours and markings are 

 scarcely to be relied upon, excepting in the adult state, in which I 

 hope to find it during the ensuing season.

 MARPESSA POMATIA.

An example of this fine and rare spider was found in Wicken 

 Fen (near Cambridge), by the Eev. F. 0. P. Cambridge in 1889. 

 This is probably a fen species, and, if so, that will account for its 

 not having been more frequently met with. Few localities have 

 perhaps been less systematically searched for spiders than the fen 

 district, in which, however, many new and rare species might be 

 confidently expected to reward the collector.
