is the larger, for the single anterior protuberance has no opening, and 

 there are, therefore, as in the Epeiridce, only two pairs of true spinners.

$ The male is extremely small, almost minute when compared 

 with the ^ ; it is represented on pi. xix, fig. 3c, in its natural size ; the 

 colour and general form does not in any particular respect differ from that 

 of the <j) ; the palpi are stout, short, the terminal segment being sub-glo- 

 bular, Avith a large opening below into which the rather thick flagellum 

 is coiled (fig. 3 d) ; the hairs all round the same are blackish and short. 

 This belongs to the fewunicoloured species of the type of Th. calycinus, 

 Linn, (citreus, Walck.). It has the anterior pair of lateral eyes 

 somewhat larger than the others, but this does not appear, as I have 

 already stated, to be a sufficient reason for instituting a separate genus 

 under the name of Xysticus. 



Blackwall (Ann. Mag. Nat. Hist., vol. xiv, 3rd ser., p. 38) describes 

 from India another species, Tkom. tuberosus which is of a brownish 

 colour. 



Loc. I found four specimens of this beautiful species inside flowers 

 in the Eden Garden at Calcutta ; not only the form of the thorax 

 but also its coloration strongly reminds one of a minute crab, the 

 backward movements are also those of a characteristic crab-spider ; the 

 specimens generally hide between the anthers where they watch for 

 insects.

? Cephalothorax quadrangular, convex, the ocular portion in front 

 truncate, a little narrowed with projecting corners, the posterior lateral 

 margins of the thorax being slightly curved ; a broad white band runs 

 posteriorly, from the antero-lateral corners, it occupies the whole length 

 of the thorax, and is slightly indented with black on each side of its 

 base ; the sloping flanks are brown, and the margins again white with 

 a very thin brown stripe at the extreme edges. The first pair of the
