vliich it is here referred under the provisional name of N. 

 viviparoj in allusion to its remarkable mode of reproduction. 

 The following are amongst the j)oints upon which further 

 information in regard to this interesting animal is desirable, 

 and will, it is to be hoped, soon be forthcoming: — (I) The 

 nature of the brood-pouch — whether this is a uterine dilata- 

 tion of an oviduct or of the vagina, as in some viviparous 

 Diptcra, or whether it is an invagination into the coelome of 

 the soft roof of the genital sinus, as in the Orthojiterous genus 

 Panesthia ; (2) the habits of the larvaj — 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 

 ohtained hy 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. Why m per 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
