Four specimens were collected in the Mergui Archipelago, 

 one of which, a very young individual, was found at Owen 

 Island. One young specimen is infested with a Bopyrid. 



They completely agree with the above quoted descriptions 

 and figures. Without doubt the species which Milne-Edwards 

 described as L. longimanus is identical with that of which 

 Miers has lately given a more extensive description. 



This species has been observed at Mauritius, Java (Miers), 

 Amboina, Pondicherry, Philippine Islands (Bumphius, Milne- 

 Edwards), Sumatra, Banka {Bleelcer). 



Genus Harrovia, Ad. Sf White. 



10. Harrovia elegan-s, n. sp. (PI. I. figs. 5 & 6.) 



One single female individual of this new species was collected 

 at Elphinstone Island. 



This species is closely allied to the two other species of Har- 

 rovia, viz. S. alholineata, Adams and White, and H. tuherculata, 

 Hasw. ; but it may be easily distinguished by the form of the 

 antero-lateral teeth of the cephalothorax, by the structure of the 

 legs, and by some other characters. 



As regards its outer physiognomy, this species much resembles 

 jff. alholineata. The upper surface of the cephalothorax is 

 hexagonal, and the distance between the last antero-lateral 

 teeth is scarcely once and a half the length of the carapace. 

 The upper surface is a little convex, smooth, though minutely
