specimen length of body 10, of carapace 4 - 5, breadth of carapace 4*25, length of first leg 

 22-5, of second 24'5, of third 2T5, of fourth 22'5. 



£. Anterior eyes further apart from one another than in the male, and the difference 

 in size between the medians and the laterals a little more pronounced. 



Vulva very similar to that of S. radiatus, but the anterior part of it rather more 

 strongly chitinized. 



Measurements in mm. Length of body 15 - 5, of carapace 6, breadth of carapace 6, 

 length of first leg 2275, of second 24"5 (that of the other side 2175), of third 22"5, of 

 fourth 23-5. 



Material. Two males (one of which has been selected as the type) and several 

 females and immature examples from Mahe" ; females and immature examples were also 

 obtained from Long Island and Silhouette. 



Remarks. According to M. Simon, Selenops radiatus, Latr., occurs also in the 

 Seychelles, but no specimens of this species were collected by Prof. Stanley Gardiner's 

 Expedition. 



38. Rhacoenemis elegans, n. sp. (Fig. 5 A, b). 



This species resembles R. guttatus, Blackw., so closely that I have not thought it 

 necessary to give a detailed description of it. It differs from R. guttatus in the following 

 respects : 



Size larger. Carapace paler in colour and with eight central spots more distinct. 

 Tibial apophysis of the palp of the male straighter and its basal portion much inflated, 

 the terminal part being slender ; a small dark tooth, which is bifid apically, is present on 

 the tibia, to the inner side of the apophysis (Fig. 5 a).

Vulva more produced than is the case in the female of R. guttatus and differing some- 

 what in shape (Fig. 5 b). 



Measurements in mm. Length of body of male 1175, of female 16. 

 Material. An adult male from Mahe, and six specimens from Silhouette, two of 

 them being adult females and one an adult male. 



Thomasettia, n. gen. 

 Carapace a little longer than broad, highest posteriorly and sloping downwards to 

 the ocular region ; a short median, longitudinal impression is present in the hinder part. 

 Eyes of anterior row sub-equal in size, equidistant from one another and slightly recurved.
