This species differs from S. delacyi (White, Ann. Nat. Hist., 3 Ser., III., 

 p. 406), which I have not seen, in its colour, in not being attenuated 

 posteriorly, and in the head being much broader and shorter. In other 

 respects the two are very similar. 



Appendix. 

 As Humbert and Saussure's paper, in which the Myriopoda taken from 

 New Zealand by the Novara Expedition are described, is not very accessible 

 in New Zealand, I subjoin their descriptions.
