length longer than the merns ; it is practically cylindrical, and the whole surface 

 is uniformly granulated, but the granules or spinules as they might almost be 

 termed, are most marked on the upper surface. The propodus is slightly 

 flattened when compared with the carpus, though both its surfaces are really 

 somewhat convex ; the granules are practically confined to its inner and outer 

 margins, where they have assumed a distinct spinose character ; they are strongly 

 marked also on the corresponding margins of the fingers. The upper surface of 

 the hand is pubescent, but otherwise almost smooth. The left chelipede extends 

 to a point opposite the middle of the carpus of the larger chelipede. It is 

 everywhere clothed with rather long hairs, and the upper margin of the 

 carpus is carinated. 



" The ambulatory legs are very long and slender, even exceeding the cheli- 

 pedes, and they are everywhere glabrous. The anterior margin of all the joints, 

 but especially the meri, carries a few setose hairs, and there is a small spinule at 

 the anterior distal end of the carpi. The dactyli are slightly bent, and flattened 

 towards their apices ; their apical portions carry long setose hairs.

" The gill-filaments are somewhat flattened, and arranged, as usual in the 

 genus, in four rows ; the filaments of each outer row are about two-thirds the 

 length of, and at the same time somewhat narrower than, those of the inner row."

Parapagurus andersoni var. brevimanm, 



Vide Henderson, J. A. S. B., Vol. LXV, pt. 2, 1896, p. 531. 



This variety only differs in the form of the great cheliped, which is altogether 

 much shorter and stouter, with the hand constituting only about two-fifths of its 

 total length : the palm is suboval and hardly longer than the dactylus, its greatest 

 breadth being nearly equal to its length. 



It much resembles P. affinis Henderson, but differs in having the large 

 cheliped slenderer and more scabrous and the ambulatory legs (2nd and 3rd 

 pair) longer and slenderer.
