ZOOLOGY OF FERNANDO NORONUA. 



616 



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. — H. N'. P.]
