56 PODOPHTIIALMOUS CRUSTACEA. 



much larger than the two posterior that have a more 

 dentiform shape , though projecting much less than in Euryc. 

 Grandidierl or in Em^yc. jVatalejisis Krauss. The supero- 

 external angle of the orbits is sharper and projects more 

 than in E. Grandidieri Al^h.. M. Edw.; the infra-orbital margin 

 is locally thickened. The external maxillipedes and the 

 abdomen constitued by 7 somites , have the same shape 

 as in Euryc. Grandidieri Alph. M. Edw. 



The latero-anterior margins and the inflected portion of 

 the carapace are covered with short hairs. 



The chelipedes are unequal in size , both in males and 

 females , but entirely smooth ; the meropodites are covered 

 by the carapace , the carpopodites furnished with an acute 

 tooth at the inner edge, and, as also the claws, wholly 

 resembling those of Euryc. Gra7ididieri Alph. M. Edw. 

 The carpopodites and propodites of the ambulatory legs 

 covered in the same manner with a few long hairs as in 

 the other species. 



The collection of the Leyden Museum contains several 

 specimens of this crustacean , but it is unknown where they 

 have been collected ; probably, however, they originate from 

 the Indian seas.

It may be allowed to observe that the genus Eucrate 

 de Haan is nearly allied to the genus Eurycarcinus, 



4. Ozius granulosus n. sp. 



This species greatly resembles the well-known Ozius 

 tubercrdosus M. Edw. , for it has the same outer shape and 

 appearance.
