A single pair of specimens has been examined ; the female is 

 about 10 mm. in length and the male about 6 5 mm. 



In P. ascidicola, according to Borradaile's figure the penulti- 

 mate segment of the third maxilliped is about 25 times as long as

The specimens were found by Dr. Asajiro Oka in an ascidian

This genus was established by Borradaile for Pontonia 

 maldivensis, 1 . a species found at Fadiffolu Atoll in the Maldives, 

 which is remarkable for the absence of exopods from all three pairs 

 of maxillipeds. 



Periclimenes beaufortensis , Borradaile ,' from Beaufort in North 

 Carolina, appears from the description to be a related form, but 

 with exopods absent from only the first two pairs of maxillipeds. 

 In both species the rostrum is toothless, but in P. maldivensis the 

 segments of the third maxilliped are broad, whereas in P. beauforten- 

 sis the appendage is described as moderately slender. The dactylus 

 of the last three legs is simple in both species. For the present at
