On Myriopoda from the Andes of Ecuador. 141 
which, it is here referred under the provisional name of N. 
vivipara , in allusion to its remarkable mode of reproduction. 
The following are amongst the points upon which further 
information in regard to this interesting animal is desirable, 
and will, it is to be hoped, soon be forthcoming : — (1) The 
nature of the brood-pouch — whether this is a uterine dilata- 
tion of an oviduct or of the vagina, as in some viviparous 
Diptera, or whether it is an invagination into the coelome of 
the soft roof of the genital sinus, as in the Orthopterous genus 
Panesthia ; (2) the habits of the larvae — whether these are 
aquatic, as in most other species of this order, or terrestrial, 
as in the single instance of the Enoicylce ; (3) the male ; 
and (4) the form of the larva-case.

XVI. — A Short Account of a small Collection of Myriopoda 
obtained by Mr. Edward Whymper in the Andes of 
Ecuador. By R. I. POCOCK, of the British (Natural- 
History) Museum. 
So little is known of the Myriopod fauna of Ecuador that any 
collection of these animals from that country is deserving of 
especial notice. But Mr. Whymper has added largely to the 
interest of his collection by devoting particular attention to 
the species found at great altitudes. This has been so rarely 
done by collectors that it is not yet possible to formulate any 
general laws with regard to the vertical range of the species 
of this much neglected group of animals ; but, so far as any 
conclusion can be drawn from the small amount of material
