however is not right: Westring, to whom I sent a specimen of M. 

 pomatia, which I had received from Simon himself, declares that 

 species to be different from A. strigipes. The spine-armature of 

 the legs etc. in M. pomatia is not such as it is stated to be in 

 A. strigipes. M. pomatia, for instance, has on the tibiae of the 1 st 

 pair, besides the four pairs of spines which are met with on and 

 near the under side, also at least one spine on each side towards 

 the base. I have on the other hand seen a very young specimen of 

 a Marpessa from Skane, which exactly suits Westring's description 

 of A. strigipes: this specimen, which I remitted to Westring, and 

 in which he recognized his A. strigipes, belongs beyond all doubt to M. 

 radiata (Grobe), of which species I have specimens sent me by Ohlert. 

 The correctness of this identification is confirmed by a coloured figure 

 of the typical specimen of A. strigipes, which Westring communi- 

 cated to me, and which exactly resembles "Euophr. radiata Ohl.", when 

 that spider is in spirits, so that only the marking on the skin it- 

 self is visible. The spine-armature on the posterior tibiae and me- 

 tatarsi is however rather variable in M. radiata: in one of the full- 

 grown male specimens from Koenigsberg, which I received from Dr 

 Ohlert, the hindermost tibiae have only 3 spines, two at the apex 

 and one nearer the base, on the under side, as is also the case in 

 a 9 j un ' fr° m the same locality, and in "A. strigipes", according to 

 Westring. In another specimen there is also a pair of spines on 

 each side of these tibiae, and the hind metatarsi, besides the spines 

 at the apex, have also a spine on the outer side nearer the base; 

 a ad., for which I am indebted to Simon, has on the under side 

 of the hinder tibiae two spines at the apex and one towards the 

 base, and moreover one spine on the outer side. In the above men- 

 tioned specimen of "A. strigipes" from Skane, which is preserved in 

 spirits and is a good deal bare-rubbed, the ground-colour of the ce- 

 phalothorax is, as in the German specimens of "Euophr. radiata", black , 

 with yellow-marbled sides, and three yellow, outward- and backward- 

 radiating stripes on both sides, behind. The black interval between 

 the two hindmost rays, which in my German specimens is of one 

 colour and broader behind, is in this specimen of "A. strigipes" divided 

 by two yellowish lines into three narrow stripes, so that here the 

 rays may be said to be 8 in number. In a couple of the German 

 specimens again, out of the six rays, the first are only imper- 

 fectly separated by some darker patches. The ground-colour of the 

 abdomen is in the specimen from Skane blackish, with a short
