NO. 2 GARTH : NEW BRACHYURAN CRABS 25 



Second and third ambulatories of normal size, propodites fringed with 

 two rows of natatory hairs. Fourth leg reduced in size, its length when 

 extended falling considerably short of the distal end of the merus of 

 the third, its dactyl a mere tooth. 



Abdomen seven-segmented, the third and fourth segments widest 

 and of approximately equal breadth; lines between segments sinuous; 

 seventh segment broader than long, tip rounded, resembling P. asiatica 

 Sakai (1933). 



Reinarh: This species is near P. nitida (Lockington) (1877), but 

 differs in the longer and narrower fingers, the gape of the fingers when 

 closed, the downward curvature of the immovable finger, the greater 

 size of the first ambulatory, and the longer and more slender dactyls of 

 the first three ambulatory legs. The measurements of the holotype are 

 identical with those of a half-grown female of P. nitida in the collec- 

 tion of S. A. Glassell. 



The capture of two female specimens in a baited "roach" trap at- 

 tached to a lobster pot and suspended in several fathoms of water sug- 

 gests that the species, while undoubtedly commensal, does not hesitate 

 to fare forth from its worm tube in search of food. 



I take great pleasure in naming this species for Mr. Steve A. 

 Glassell, whose unflagging interest in the unusual habits of these little 

 crabs and whose persistent efforts in searching out a number of so-called 

 "lost" species have resulted in our better understanding of their rela- 

 tionships and peculiar mode of life.
