Of this species, which had formerly been found in 

 Amboina only, Mr. Oates has captured an adult female in 

 Table Island. The area occu])ied by the four middle eyes is 

 in this specimen not perceptibly broader behind than in front ; 

 in other respects it appears to be exactly similar in form to 

 the types of the species. The colour shows but a few slight 

 differences. The tarsal joint of the (yellowish) palpi is 

 blackish ; the middle area of the back of tiie abdomen has 

 behind, instead of three pairs of small silver-coloured spots, 

 two longitudinal, nearly parallel, close-set, silver-coloured 

 lines ; tiie sides of tiie abdomen are blackish, with a long, 

 somewhat oblique, and slightly sinuated silver-coloured band, 

 united anteriorly with the silvery pattern of the back, and 

 they show' also a small spot of the same colour, situated more 

 below, near the base. Tiic vulva consists, as in the types, of 

 a small, pale, almost seniicircular fovea, surrounded in trout 

 and on the sides by a low, backward-curved callus, which is 

 black on the sides and pale in the middle. 



The length of the specimen is 8g millim. ; length of cepha- 

 lothorax If, of abdomen 2^ millim.; legs, I. 0§, II. 7|,
