1905. ] FROM CHRISTMAS ISLAND. 549 
legs are unfortunately wanting); and likewise a female 50 mm. 
long with the female from Christmas Island. 
In a paper on some species of this genus (in the Transactions 
of the Linnean Society of London, 2nd ser. Zool. voi. ix. pt. 8, 
1904, p. 292), I have already alluded to the fact that in adult 
specimens of Pal. lar Fabr. from Tahiti, described by me as a 
variety spectabilis, the ambulatory legs presented a stouter shape 
than in specimens of the same size from Halmahera; but I do not 
venture to say now whether the Prawns from Christmas Island 
belong to that variety or not, because they are considerably 
younger.
