STALK-EYED CRUSTACEA 339 



2. Homolodromia. 



Homolodroinia ... A. Milne Edwards. 



The carapace is narrow, wider behind than in front. 

 The internal antennae cannot be folded in the subfrontal 

 fossa. The external antennse, very movable, are inserted 

 below the ocular peduncles ; they are longer than the 

 carapace. The eyes are small. The buccal cavity is 

 quadrilateral ; the epistome is very distinct. The teeth 

 of the extremity of the pincers are sharp. The legs of 

 the second and third pair are very long and frail ; those of 

 the fourth and fifth are folded on the back, small and 

 cheliform. 



The abdomen of the male has seven joints, which are 

 in contact only in their median portion, their lateral part 

 being narrow and free. 



Range. — West Indian Sea. 



I. Homolodromia paradoxa. 



Homolodroinia paradoxa . . A. Milne Edwards. 



The carapace is thick, very curved transversely, and 

 clothed in down which does not hide the test; its surface 

 is smooth. The front has two strong and triangular 

 rostral horns, which extend as far as the end of the second 

 joint of the external antennas ; there is a large postorbital 

 spine directed outwards, and a little in front. The lateral 

 borders are unarmed and almost parallel. The latero- 

 inferior regions are unarmed. 



The anterior legs of the male are feeble, of the same 

 size, covered with hairs, but smooth. The point of the 

 immovable finger is divided to receive the point of the 

 movable.
