152 STALK-EYED CRUSTACEA 



I. Ozius reticulatus. 



Ozius reticulatus ... A. Milne Edwards. 

 Lagostoina reticulata . . Desbonne and Schramm. 



The carapace, wide behind, is more than once and a 

 half times as broad as long ; it is sloped anteriorly but 

 flat behind and transversely. It is deeply eroded along 

 its antero - lateral borders ; the regions are not well 

 marked. The front is inclined, bimarginate. The 

 antero-lateral borders are long and thin, and their con- 

 tour is regular. 



The colour is red with yellow patches ; the pincers are 

 brown. 



Range — Jamaica, Martinique, Guadaloupe.

The carapace is broadly oval, the antero-lateral 

 margins being cut into lobes. The front has a notch in 

 the middle line, and is divided on each side of this notch 

 into small lobes. The surface of the carapace is more or 

 less smooth, with the regions indicated by faint lines or 

 furrows. The basal antennal joint, instead of being joined 

 to the front, is very small, and it is the second joint which 

 at its extremity reaches the frontal border; the antennu- 

 lary fossa is imperfectly separated from the orbit. The 

 external maxillipedes are short, and the fourth joint is 

 subquadrilateral and truncated on the inside for the 

 insertion of the fifth joint ; their edges do not meet in 

 front of the buccal cavity, but have a wide interspace
