This little spider is easily recognized by a tuft of tolerably 

 short, thick bristles, arranged almost like a comb, on the tibial joint 

 of the palpus in d*. It is not described either by Blackball or 

 Menge. — I have been furnished with original specimens of both Neriene 

 corticea and Micryph. cristatopalpns through the kindness of Messrs 

 Cambridge and Ohlert.

This species differs from all others belonging to the genus 

 Erigone that I know of, in that the anterior tibiae and metatarsi 

 are, on the under-side, armed with a double row of spines, which 

 are considerably coarser in £ than in cf. The three long bristles 

 along the back of the cephalothorax, which Westring mentions, 

 but which Menge has not found upon his specimens, are easily visible 

 not only on several females in my collection, but also on a cf sent 

 me by Westring.

Menge has applied the specific name brevis Reuss to this spider, 

 and I have also retained it, for Keuss' description suits the species 

 well, though his figures are bad. It is excellently described by 

 Ohlert under the name of Micryph. jiliceopus C. Koch, and I have 

 also received it under the same name from Dr L. Koch. 



In E. brevis the tibial joint of the male's palpus is rather lon- 

 ger than the patellar joint; it has at the base, on the outer side,
