 without scales. The hitherto kuowu forms with eyes aud 

 free-living. Subfamily Paronellixj: (C. B., ll'OU). 



ii. Deutes with dorsal ciliated scales or ciliated spines, these at 

 the bases of the dentes pass over into ciliated bristles. 

 Coxas generally distinctly longer than the trochanters (also 

 in 2'roglopedeics ?). Empodial appendage with 3 Aving- 

 corners, or more or less reduced, loveless and scaled. 



Subfamily Cyphoderin^ (C. B., 1906).

B. Body pear-shaped to almost globular, as a rule, with obsolete seg-

 especially the abdominal terga and pleurse not differentiated. The

 Coxce elongated, also on the outer side distinctly longer than the 

 trochanteral segment. Ano-genital segment concealed under the 

 furcal segment (seen from above). Abdominal sensory setae 

 absent. 7. Family Neelid^, Folsom, 1896. 



b. AntetintB inserted behind (over) the middle of the head, generally 



considerably longer than the head-diagonal, not rarely with 

 subdivided segments. Head with distinctly elevated vertex over 

 the neck. Corpus tenaculi (generally) with bristles. Coxa not 

 elongated, on the outer side considerably shorter than the inner 

 side and than the trochanteral segment. Ano-genital segment 

 not concealed under the furcal segment. Abdominal sensory 

 setae present. 8. Family Sminthurid^, Lubbock, 1862. 



1. Ventral sac (tube) even in full-grown animals smooth-icalled 

 (seldom at the tips with small warts — after Linnaniemi). 

 Corpus tenaculi with lateral appendage (stylus ?) at the base 

 of the rami. Integument granular. Tracheae (always?) 

 present. Subfamily Sminthuridin^, C. B., 1906 



* Anal and genital segment fused, on each side with two (one 

 small) sensory setae. 



Tribe Sminthuridini, C. B., 1913. 



** Anal and genital segment separated, sometimes the latter 

 fused with the furcal segment. The genital segment with
