Humbert, A. Essai sur les Myriapodes de Ceylan. Mem. Soc. 
de Pliys. et d^Hist. Nat. de Geneve, tome xviii. pp. 1-62, 
plates 1-5 ; July 1865. 
In this memoir M. Humbert gives descriptions of all the 
known species of Cingalese Myriopoda, illustrated by numerous 
figures of great beauty, executed by M. A. Lunel. The species 
deseribed belong to the genera Scutigera (1), Scolopenclra (5), 
Heterostoma (1), Mecistocephalus (2), Pohjdesmus (11), Sphcero- 
pmis (3), Trachyjulus (1), Spirostreptus (6), Spirobolus (3), and 
Siphonophora (1) ; total 34, of which 22 are described as new.

plates (read T6th June, 1865). 
In this valuable monograph the author not only describes the 
North- American species of the Class Myriopoda, but enters into 
an elaborate discussion of the principles of their elassification. 
His results will be given further on. The synoptical table of 
the species (pp. 244-248) will be found useful in their determi- 
nation, and the full description given of the details of structure, 
illustrated with numerous woodcuts, may, it is to be hoped, in- 
duce other entomologists to take up the study of this interest- 
ing but neglected elass.
