This species most closely resembles the one figured by Savigny (in 

 the Exped. de l'Egypt, &c.) as G. arenoides. Koch (Archiv fur 

 Naturgeschichte, viii, 1842, p. 353) considers it distinct from the 

 European G. arenoides of Pallas, and names it G. Arabs. This 

 species is, according to Koch, pale yellowish, with two brown stripes 

 on the falces, two large spots on the cephalothorax, and a longi- 

 tudinal stripe on the body. The present species differs from it 

 by the want of any spots on the cephalothorax and by having in both 

 sexes the palpi much longer in proportion to the body. 



Loc. The two figured specimens were obtained by Mr. T. H. 

 Hughes in the Birbhum district of Western Bengal ; I have also 

 obtained lately some specimens from the neighbourhood of Delhi 

 through Mr. R. Mitchell ; the species appears to be common there. 



Order, PHALANGIDEA. 

 Family, PHALANGIBJE. 



The Phalangid^; belong to a small division of Arachnoidea, which 

 have the cephalothorax not distinctly separated from the abdomen, 

 but, in other respects, greatly approach true spiders ; they have the 

 feet usually very long and slender in proportion to the body, and 

 the thorax bears on a prominence two large eyes ; in some species two 

 other small accessory eyes are said to exist ; the falces consist of 

 two segments the second of which is didactylous at the end, possessing 

 a moveable short claw. 



The vitality of the feet of the Phalangia has been often noticed, 

 and I would call the attention of any one interested in the subject to
