Blackwall — Spiders Captured in the Se>/chellcs Islands. 11 



yellowish-wliite colour, tlic under part being the palest ; the sides are 

 freckled with small brown spots, and there is a series of spots of a 

 similar hue, having an angular form and somewhat larger size, that 

 extends along the middle of the npper part, but is not continued to its 

 extremities ; two large black spots occur on each side of the under 

 part ; the anterior ones comprise the branchial opcrcula, and the 

 posterior ones, which are the largest, are pointed at their posterior 

 extremity. 



I have felt some difficulty in assigning a place to this spider in tlio 

 family Thomisidte, to which its immature state has in some measure 

 contributed. In several particulars, and especially in the figure of its 

 lip, it resembles certain species belonging to the genus Olios, but I 

 have been induced by its predominant characteristics to include it, 

 provisionally, in the genus Sparassus. 



[Whatever this spider may be, it is certainly not a Sparassus, and, 

 in spite of a very laterigrade appearance, it probably belongs to the 

 Drassides rather than to the Thomisides. I have a very nearly allied, 

 though distinct (and as yet undescribed), species of the genus to which 

 it belongs, from Ceylon. Dr. Ludwig Koch, to whom I forwarded 

 examples of the Ceylon species, says they are certainly of the family 

 Drassides, and, in his opinion, of the genus Leiocranum, L. Koch. 



It will probably be necessary to found a new genus upon these spiders, 

 differing, as they do materially, from the typical Leiocranum, into which 

 genus I cannot at all fit them. In giving the above opinion I am 

 supported by the difficulty felt by Mr. Blackwall in regard to assigning- 

 this spider a place in the family Thomisides, and by his placing it, 

 provisionally only, in the genus Sparassus — (see the remarks at the end 

 of his description).] 



Family DEASSID^. 

 Genus Clubiona, Latr.

Length of an immature female, o^ths of an inch ; length of the 

 cephalothorax, ^o" ; breadth, iV ; breaclth of the abdomen, -^^ ; length 

 of a posterior leg, -iV ; length of a leg of the third pair, i. 



The abdomen is oviform, pointed at the spinners, which arc promi- 

 nent, thinly clothed with white hairs, moderately convex above, pro- 

 jecting over the base of the cephalothorax, and is of a pale-yellowish 

 colour ; a series of six small black spots, disposed in pairs and almost 

 contiguous, extends from the anterior extremity of the upper part 

 along the middle nearly half of its length, and is followed by a series 

 of eight very minute spots of the same hue, also disposed in pairs, but
