[?] MYUIOPODA. 
Peripatm capensis, Grube. Observations on its structure and develop- 
ment by H. N. Moseley, P. R. Soc. xxii. pp. 344-350, from specimens, 
collected at the Cape of Good Hope, during the ‘ Challenger ’ expedition. 
The opinion of Quatrefages and Gervais as to the affinity of Peripatua 
to the Myriopoda is partially confirmed. In many points of habit and 
tracheal structure it resembles Julus, but no structure like that of the 
heart of Myriopods was found in the dorsal vessel. It is certainly not 
hermaphrodite, and the wide divarication of its ventral nerve-cords pre- 
vents its being considered a degenerate form. It has affinities to all the 
main branches of the Tracheata ; and the author suggests that the 
Myriopods may be most nearly allied to it, and form a distinct branch 
arising from it, and not passing through insects. Peripatus itself may 
well bo placed among Hackel’s Protraclieata. 
Moseley has subsequently given a more elaborate and illustrated account 
in Phil. Tr. clxiv. pp. 757-782, pis. Ixxii.-lxxv.
