Typus : Genus Canibala ex America boreali. 



This fomily comprehends two sub-families, Glyphiocambalinae and Mastigocam- 

 balinae. To the first sub-family belong the genera Glypliiidus Gerv. Hypocambala .Silv. 

 Agastrophus.- Attems, ? Trichocajuhala' Silv. and lulomorpha For. without fiagellum 

 in the anterior copulatory legs of the male ; and to the Mastigocambalinae the genera 

 Canibala and Dimerogomcs, that have a well-developed fiagellum. 



Diiiicrogonus is very distinct from Canibala by the absence of longitudinal crests on 

 the segments of the truncus. 



The family of the order Diplocheta, very close to the Canibalidae, is that of the 

 Nannolenidae, which comprehends only the genus Nannolene Bollman, and is distinct 

 from Cambalidae by the broader Hypostoma, shorter stipites interni and presence of 

 one pair alone of the copulatory organ, as in Pseudonannolenidae and Physiostreptidae, 

 although, as in the named family, the 6th segment of the truncus wants ambulatory legs. 



' For the nomenclature of the mouth part.s cf. my work -'Classis Diplopoda, Vol. i. Anatome ; Pais i^ 

 Segmenta, Tegumentum, Muscuh " [in] " Berlese's Acari, Myriopoda et Scorpiones,^' Portici 1903. 



- The genus Agastrophus Attems (Zool. Jahrb. xni. p. 151) is a synonym o'i Hypocambala .Silv.. I think, 

 but why the author does not describe the labium, I am not sure. 



■■ I ascribe with doubt Trichocambala to this family, because I know not the male.
