ZOOLOGY OF FEENANDO NOEONHA. 
515 
third, and fourth pairs of legs spined ; posterior margin of second 
and third pairs produced distally into a small acute spine. 
Colour (of specimens preserved in spirit of wine) red or yellow 
above, with darker spots, reddish pink beneath. 
Three specimens. Length and width of carapace in largest 
specimen 14 mm. ; length of manus and pollex 20 mm. 
The specimens that I have here described and identified pro- 
visionally as P. marginatus (Stmps.) are evidently closely allied to 
P. asiaticus (Leach), the common Indo-Pacific form, and I am 
doubtful if they should be regarded other than as varieties of 
that species.

The species occurs on the tropical coasts of the Atlantic. 
Twenty-three specimens, two of which are females with ova, 
were taken. [Very common on the sandy shores. When a 
wave broke, these little Crustacea were often seen running and 
burying themselves in the sand as the water retired. — II. N. P.]
