ANOMOURA PAGURIDEA. 4^ 



Anterior feet subequal. Fingers moving in same vertical plane, cor- 

 neous at tips, spoon-excavate. Front short rostrate. 



The hands are short and subequal and the front rostrate, as in the 

 Clibanarii; but the position of the hand is similar to that of the 

 Paguri, the fingers having an up and down motion, instead of a 

 lateral, owing to the different mode of articulation of the hand with 

 the carpus. 



Antculus typicus, Dana. 

 Plate 29, fig. 1, animal, natural size. 



Raraka, Waterland, and Carlshoff Islands, Paumotu Archipelago ; 

 also, Wakes Island, Pacific Ocean. 



Colour, while living, as in the figure, much brighter in its tints 

 than in Quoy and Gaymard's figure, Voy. de 1'Uranie, pi. 79, fig. 1. 

 Length of specimen, four inches. The anterior part of the carapax 

 has the median region distinct, and moreover, what is unusual in this 

 genus, the extramedial and intramedial areolets are distinct, the latter 

 having the form of a narrow arrow-head.
