 Armadillo rectifrons DoUf. in Weber, Reise Niederl. O.-Ind. IV. 

 361. Tb. 13. f. 4. 



Patria: Celebes. 



Sectio XIII. To this lOTOup belong all the species 

 of Spherillo, which have the epimera of the first truncal 

 segment thick and more or less evidently sulcate at the 

 margin, exceptions are but S. sollers, S. Macmahoni, S. ha- 

 waiensis, S. grossus building proportionately the sections 

 II — V; also the hinder margin of the first segment is 

 straight in almost all species. All the species seem to be 

 mutually related, only S. lentus takes a separate place.

*) I am not completely sure of the exactness of the last character 

 because when I examined the two species many years ago I did 

 not pay particular attention to this character; also I am uncer- 

 tain with regard to the relations of the pleopods in these two 

 species.
