1. The Reproduction of Peripatus Leuckartii, Sänger. 



By Arthur Dendy, D. Sc, Melbourne University. 



eingeg. 14. September 1891. 



Peripatus Leuckartii has proved to be by no means uncommon in 

 Victoria ; it is now recorded from a good many distinct localities, and 

 forms a very characteristic constituent of what I have elsewhere 1 

 termed the »Cryptozoic Fauna«. I have already shewn 2 that it varies 

 considerably in colour and marking, but it may always be readily 

 distinguished from the only other Australian species of Peripatus (P. 

 insignis 3 ) by the number of its legs and the presence of an accessory 

 tooth on the outer jaw. Hitherto little has been known of its habits, and 

 nothing of its mode of reproduction. The only observer , so far as I 

 am aware, who has said anything concerning its life-history is Mr. 

 Fletcher, who has described 4 four very young individuals, the pro- 

 geny of a female kept by him in captivity in damp moss and leaves for 

 four months (July to October, inclusive). Mr. Fletcher did not ob- 

 serve the birth of the young but found them in company with the 

 mothe" when apparently only a few days old. He assumes, naturally 

 enougi , that they were born alive, as in all other species of Peripatus
