gation of the cheliped. A single mature Pelia from the Galapagos Islands, 

 where none has been collected since the holotype, would settle the ques- 

 tion of rostral length, as well as that regarding the presence and nature 

 of the digital tooth, the tubercle mentioned by Bell being on the pollex, 

 as well as providing the essential first pleopod for comparison with the 

 mainland species. Lacking such a specimen, it seems best to treat P. 

 pulchella as distinct from either P. tumida or P. pacifica for the present.
