I agree with Dr. Latzel in considering Trachelodesmus as a subgenus 

 of Scytonotus. The subgenera may be distinguished as follows : 



a. Anterior segments not strikingly attenuated; antennas and legs normal. ■ 



Scytonotus. 



aa. Anterior segment noticeably attenuated; legs rather long; antennae long and 



slender Trachelodesmus. 



24. SPELEROTHERIIN.E. 



1833. — Sphairotheria Brandt. Bull. Soc. Natur., Moscow, vi, 198. 



The subfamilies of Glomeridw established by Brandt and retained by 

 other authors are probably valid. In accordance with common custom 

 I have changed Sphcerotheria to Sphcerotheriincv. 



25. Glomerin.e. 

 1833. — Glomeridia Brandt. Bull. Soc. Natur., Moscow, vi, 194. 

 This subfamily should be called Glomerince and not Glomeridia. 



26. Meinertia, nom, gen. nov. 



1870. — Scotophilus Meinert. Myr. Mus. Haun., Pt. 1, 40 (bicarinatus). 



As Scotophilus Meinert is preoccupied {Scotophilus Leach, Mamm., 

 1822; Scotophilus Swains., Aves, 1837), another name must be used as 

 a substitute, and I propose the above name in honor of its original 

 describer, Dr. Meinert, to whom all myriapodists are indebted for his 

 excellent works on the Chilopods.

1847, — Stenonia Koch. Syst. Myr., 85 and 187 (in pai't; Geophihis acuminatus Leach = 



Linotcenia acuminata (Leach)). 

 1847, — Linotcenia Koch. Syst. Myr., 86 and 188 (GeopMlus crassipes Koch = Linotcenia 



acuminata (Leach)). 

 186(3, — Scolioplanes Bergsoe and Meinert. Nat. Tidsskr., iv, 98 {Geophihis maritimus 



Leach, GeopMlus acuminatus Leach, and Linotcenia crassipes Koch = 



Linotcenia acuminata (Leach). 



In their work on the " Danemarlc's Geophiler,^ Bergsoe and Meinert 

 erected the genus Scolioplanes, which included Geophilus maritimus 

 Leach, Geophilus acuminatus Leach, and Linotcenia crassipes Koch, 

 but as the last species {crassipes Koch = acuminata Leach) was the 

 type of Koch's Linotcenia, the latter name must be used in place of 

 Scolioplanes. 



The true type {Geophilus linearis Koch) of Stenotcenia is a Geophilus, 

 and Stenotcenia must be considered identical with Geophilus.
