CANCROIDEA. 197 



Plate 11, fig. 2, animal, enlarged three diameters. 



Tutuila and Upolu, Samoan Group, and Wakes Island Pacific; also 

 Paumotu Archipelago ? 



Colour purplish red, or deep red. Length of carapax in one speci- 

 men (male), 2-9 lines; greatest breadth, 4-8 lines; ratio of length to 

 breadth, 1 : 1-66; in another specimen (female), length Si lines; 

 breadth, 51 lines; ratio, 1 : 1-65. This is a very neat, smooth-looking 

 species, with narrow, even furrows between the areolets. Under a 

 lens, the anterior part of the carapax is decidedly granulous, and 

 somewhat uneven, and the hands and carpus are similarly granulous, 

 the granules on the outer surface of the hands partly in series. 



2. Carapax granulatus aut tomentoms. 



Actjeodes tomentosus {Edwards), Dana. 



From the Samoa and Feejee Islands, Pacific Ocean ; also from the 

 Sooloo Sea, East Indies, and the Mangsi Islands. 



In this species, areolet 2 M is longitudinally divided into two nearly 

 equal parts, each showing, through the tomentose covering, about a 

 dozen points or minute tubercles having a smooth surface; areolet 3M 

 is divided into three parts, the narrow anterior portion being one, and 

 the rest being medially bisected; areolets 1 L, 2, 3, 4, 5, 6, are all dis- 

 tinct and simple, and 2 L is nearly of the same size as either half of 

 2 M. IP and 2 P are oblong transverse and rather broad, and sepa- 

 rated by a depression. 1 R, 2 R are simple, the former about twice 

 as large as the latter, yet in small specimens they appear coalesced. 



The whole under surface of the body has a tomentose coat like the 

 upper, and it covers densely the outer maxillipeds, which are coarse 

 granulous. The fingers of the hand are enveloped by it nearly to the 

 tips, beside being very closely set with minute points.
