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 (Jhers), 
Amboina, Pondicherry, Philippine Islands (Atumphius, Milne- 
Edwards), Sumatra, Banka (Bleeker). 
Genus Harrovia, Ad. & White. 
10. HaRRovIA ELEGANS, 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. H. albolineata, Adams and White, and H. tuberculata, 
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 
H. albolineata. 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
