CARDISOMA URVILLEI. 33 



of the first joint of the external antennae and the shape 

 of the internal suborbital lobe that separates the antennae 

 from the front , agree entirely with the same parts of 

 C. carnifex. Anterior legs unequal , hand of bhe larger leg 

 almost as long as the breadth of the carapace. Lower 

 and outer margins of the arm armed with numerous teeth , 

 upper margin transversely wrinkled. Upper surface of the 

 wrist , as also upper and lower surface of the hand gra- 

 nulated ; external surface of the hand a little granular. In 

 the same manner the upper margin of the mobile finger 

 and the lower margin of the index are provided with nu- 

 merous granules. Ambulatory legs wholly resembling those 

 of C. carnifex Herbst. 



17. Car dis oma urvillei, M. Edw. 



Milne Edwards, 1. c. pag. 304. 



A very fine male specimen was collected by Mr. Forsten 

 in the Moluccas. 



This species is also closely allied to Caixlisoma carnifex , but 

 differs by the following characteristics: Carapace comparatively 

 a little broader with very tumid branchial regions , no trace 

 of a raised line defining the antero-lateral margins. Orbits 

 transverse, as broad as the front, but comparatively higher than 

 those of C. carnifex, though having the same shape. The 

 internal suborbital lobe and the first joint of the external 

 antennae having a striking resemblance to the same parts 

 of the common species. Anterior legs unequal, the left 

 being larger; the hand of the larger leg nMch longer than 

 the breadth of the carapace. External and internal sur- 

 faces of the hands quite smooth ; fingers curved , especially 

 those of the large hand, so that, when closed , they do not 

 rest upon each other , somewhat granulated at their ends. For 

 the rest this species agrees entirely with Caixl. carnifex. 



Breadth of carapace (the swollen lateral parts of the 

 body included) 90 mm., length G7 mm. Length of the 

 hand of the larger leg 110 mm.
