Genus Anisaspis, E. Simon. 



Type. A. tuhereuluta, E. Sim. ( $ ), Proe. Zool. Soe. 1891, p. 549. 

 Hob. St. Vincent, West Indies. 4-6 mm. long. 



Types, three females in coll. Brit. Mus. Nat. Hist.' (Plate 

 XXXIV. figs. 3, 4, 5.) 



Having carefully examined the three specimens referred to 

 above, I find that, doubtless owing to an oversight by the author, 

 they do not entirely agree with the generic diagnosis given 

 in Hist. Nat. Ar. i. 1 , 1892, p. 78, in, at any rate, one very im- 

 portant character — " Oephalothorax humilis et fovea carens." This 

 character is certainly not distinctive of the type specimens. Being 

 encrusted with grit, a feature which seems to be common to the 

 females of this subfamily, and the centi-al fovea being tilled up, it 

 doubtless escaped observation. Prom two of the three specimens 

 however, this grit was carefully removed, and a distinct, deep 

 fovea laid bare. The other specimen certainly to all appearance 

 merits the description " Cephalotliorax humilis et fovea carens " ; 

 but it is only in the appearance that it does so. 



There are three characters, however, in which these type 

 specimens differ from the female to which I have assigned a new 

 generic position (Anisaspoides), as well as from Paratropis. Simon 

 says of them : — " Mamillce duai — idtimo medio multo breviore et sub- 

 rotandato " ; "parte labiaU apice arcuuta et remote spimilosa " ; and 

 "pedum unf/iie inferiore nidlo." 



Whether the last of these characters is of any real significance 

 for purposes of classification in a group in which there is evidently 

 a tendency towards obliteration of the inferior tarsal claw, I am 

 not in a position to judge ; but, for the present, one would scarcely 

 be justified in including in a genus, of which one of the chief 

 characters lies in the total absence of the inferior tarsal claw, a 

 spider which possesses a distinct inferior claw on the tarsi of the 

 first two pairs of legs. 



A. Mamilla; four rarutropis, Sim. 



B. Mamilla! two 



1. Olaws on anterior tarsi— i. and ii.— three Anisaspoide^, n. g. 



2. Claws on all four tarsi — i., ii.,iii., and iv. — two only. Anisaspis, Sim. 



Genus Actinopus, Perty, 1833. 

 (Type, A. tarsalis, Perty.) 

 AcTiNOPUS WAiiLACEi ^, u. sp. (Plate XXXV. fig. 18.) 

 $. Hah. Santarem. Type in coll. Brit. Mus. Nat. Hist. 1896. 

 Colour. — Carapace pale testaceous brov^'n, cephahc area darker. 

 Base and centre of thoracic area pale testaceous. Base of man- 

 dibles very dark brown, clothed along the ridge and over the apex 



' The specific name under which the type is described in op. cit. is " tuher- 

 culata," not " bacilli/era " as quoted, no doubt bv an oversight, in Hist. Kat. 

 Ar. 1892, i. 1, p. 78. 



■^ I have much pleasure in connecting this species with the name of Mr. W. 

 Wallace (senior), of Santarem, through whose courtesy I was enabled to spend 

 a fortnight in the heart of the forest, lodging in his plantation at the Sitio 

 Andirobal.
