A specimen of J/. ?/(<7?'(7,Walckenaer, preserved in tlie British 

 Museum, and bearing Walckenaer's ticket, and forming part of 

 the collection of M. Lucien Buquet, may be regarded as the 

 type of the species. I believe it to be the female of the 

 species described by Ausserer as Homceomma versicolor, and 

 later by Cambridge as R. Stradlingii. 



In addition to this specimen, the British Museum has 

 three adult male examples from Brazil. 



Homceomma villosum (Keyserling).

 Nat. Hist. (6) xvi. p. 226). 



These two species may be distinguished as follows : — 



a. Length of carapace 18 millim. ; process on palpal bulb 



short and conical ; protarsus of first leg strongly arcuate *, 

 without inferior basal noduliform prominence ; carapace 

 shorter tlian protarsus of fourth leg ; tai'sal scopulse 

 of third and fourth legs not completely divided by a band 

 of bristles nigrum. 



b. Length of carapace 10 millim. ; process on palpal bulb long, 



cylindrical, ^ith expanded tip : protarsus of first leg 

 scarcely arcuate, with distinct inferior basal pnjminence ; 

 carapace longer than protarsus of fourth leg ; tarsal 

 scopulae of third and fourth legs divided by a band of setee. villosum.

 Miaschistopus, Pocock, Proc. Zool. Soc. 1897, p. 769, 



Simon regards Metriopelma as a synonym of Crypsidromus^ 

 the type of which, namely isahellinus, came from Rio 



* C. Koch's figure of Mygcde versicolor represents the protarsus of this 

 leg as straight.
