ANOMOURA PORCELLANIDEA. 423 



PORCELLANA COCCINEA, Owen. 



Sandwich Islands, island of Maui. 



Length of carapax, 7*1 lines; breadth 7 lines, or slightly less 

 than length, although the body looks oblong. The beak is prominent 

 triangular, with a small tooth either side over the base of the eyes ; 

 the post-orbital angle is acute, and there is a short spine on the side of 

 the carapax, a short distance posterior to the orbit, besides two or three 

 denticulations between this spine and the angle of the orbit. Posterior 

 to this spine there are no others on the sides of the carapax. The 

 carpus in our specimen has three oblong teeth on the inner margin, 

 ^exclusive of the inner apical angle. The third joint of the second, 

 third, and fourth pairs of legs is laterally short hirsute, and the upper 

 margin is spinous. The hand is minutely squainato-granulous. The 

 rugosity of the carapax is faint, though distinct with a lens. The 

 flagellum of the outer antennas is naked. Under a lens, the trian- 

 gular beak is a little denticulate either side, near the lateral tooth, 

 where it is somewhat dilated, and just above there is a prominent 

 point. The body is depressed and rather thin ; the hand is thin.

 described by Owen, were from the Paumotu Archipelago.
