ANOMOURA PAGURIDEA. 473 



Raraka, Vincennes, Carlshoff, and Waterland Islands. Collected 

 August, 1839. Found mostly in a white Cerithium; also, in Naticas, 

 &c. 



Length, one and one-fourth to one and one-half inches. Colour, 

 a light flesh-tint; anterior portion of carapax, nearly white; legs, 

 whitish, but a flesh tint towards the base, and a little brown spotted 

 with white at base of some of the joints ; abdomen light flesh-tint or 

 white ; antennae deep flesh-colour ; pigment of eyes brown. 



This species resembles the rugosa, but is more square in form, less 

 hairy in its legs, and much more delicate in shade of colour. The 

 back and sides of carapax anteriorly meet in a right angle, the edge 

 being neat and exact. The eyes are longer and more compressed 

 triangular, and the edges are more trenchant, not at all rounded. 

 The arm of the anterior legs is wedge-shape, with a flat surface, being 

 trenchant above, and having the sides quite flat; and the oblique 

 truncation of the apex produces a triangular flat surface, slightly 

 rounded above. The large hand is without the series of rugules, cha- 

 racterizing the rugosa. The flagellum of the second antennae is nearly 

 as long as the carapax. 



CENOBITA CLYPEATA. 

 Balabac Passage. 



Length, four and three-fourths inches. Front narrow. Upper 

 flagellum of inner antennae about one-fifth as long as lower. Anterior 

 region of carapax convex, and other characters as mentioned by 

 Edwards for the clypeata. The large hand (Plate 30, fig. 4 a) is two 

 inches two lines long ; breadth, one and a half inches ; inner surface 

 near upper margin naked ; outer surface hardly smooth in any part, 

 but covered with quite small tubercles, with horny summits and sub- 

 acute. Tarsi quite rough with similar points and sparsely hirsute. 



Var. brevimanus. Has the characters of the above, but the larger 

 hand (Plate 30, fig. 4 5) is but little longer than broad, nearly cir- 

 cular in outline, and very convex and nearly smooth on the outer 

 surface, the length, sixteen lines; breadth, thirteen and a half lines.
