Keuss' synonym for this species is not altogether certain. The 

 projection between the four central eyes in the specimen, with which 

 Westring kindly favoured me, is by no means so large as in Keuss' 

 figure (loc. cit.) , but in other respects Keuss' description and figure 

 suit this species very well, especially as regards the position of the 

 eyes. The 4 central eyes in cf form a long narrow rectangle; the 

 posterior central eyes are placed uncommonly close to each other 

 (they are almost contiguous), and the distance between the posterior 

 lateral and the posterior central eyes is double the diameter of an 

 eye, whereas in the nearly related E. cuspidata (Blackw.) 1833 ') 

 the distances between the four posterior eyes are about equal. The 

 tibial joint of the palpus, besides the large lamellar projection cloven 

 at the apex and curved ontwards, which protrudes from the upper 

 side of the extremity of the joint, inwards, has another shorter pro- 

 jection on the outer side of this, in the form of a pointed spine 

 bent downwards (which is absent in E. cuspidata); it has also 

 a short and blunt, coarse process underneath. Blackwall's descrip- 

 tion of his \Valcke?iaera ?nonoceros agrees well with Westring's spi- 

 der, but his figures furnish but little information. 



A male specimen of Lophomma cristatum sent me by Menge, 

 shows not the least difference from Westring's specimen of E. mo- 

 noceros. Menge does not mention the conical protuberance between 

 the eyes, on which the hair-tuft is placed. 



Of another nearly allied species, E. (Walckenaera) nnicwnis 

 Cambr. 1861 2 ), which is identical with Micryphantes stylifer Ohl. 3 ), 

 and, according to the typical specimen kindly communicated by 

 Menge, with Cornicularia monoceros Menge 4 ), and which is distin- 

 guished by the little process between the four central eyes being
