this section*), and I have at that time demonstrated in 

 what manner the two lamels, formed of the split hind cor- 

 ner of the first truncal segment, gripe in the space between 

 the two lamels of the split epimer of the second truncal 

 segment. 



The articular face (pronotum) of the segments in 

 the largest part of the species is also very short, linear, 

 ordinarily but a twentieth part to a tenth part of the 

 length of the back of each segment; in some species the 

 pronotum is, however, a little longer particularly in the 

 hinder segments of the truncus; for instance the Armadillo 

 hirsutus Koch, which I place in this group, is in this man- 

 ner distinguished fi'om the species of the proceeding section. 

 An exact research with regard to this character in all the 

 species will probably give good results. The appendices of 

 the uropods mostly the exopodit are always very small. 



The species after my opinion belonging to this section 

 I have set in order after their affinity as much as it has 

 been possible after the often very imperfect descriptions of 

 the various authors. Furthermore I give a survey of tlie 

 chief characters and the classification of the species in 

 consequence of them, thinking it will be useful for later 

 finding out the systematic relations between the numerous 

 species belonging to this group.
