394 Prof. A. Dendy on the 



the occurrence of a form with sixteen pairs of legs instead of 



fifteen. 



Of Land-Planarians only three species have as yet been 

 described from New Zealand ! The first was Moseley's 

 Geoplana Ti-aversii, received from Mr. Travers when H.M.S. 



* Challenger ' was at Wellington, and described by Professor 

 Moseley in the Qu. Jour, of Micr. Sci. 



In the Trans. New Zeal. Inst, for 1880 Captain Button 

 described two more species from Dunedin and Wellington, 

 which he named Geoplana Moselei/i and Rhynchodemus 

 testacevs respectively. The latter, however, proves to be also 

 a Oeoplana. 



The Land-Planarian fauna of New Zealand promises to be 

 exceedingly rich, and I am already able to add thirteen species 

 to the above list, four of which were found in my own 

 garden at Christchurch, while for others I am indebted to 

 the kindness of many friends who have interested themselves 

 in the matter on my behalf. The additions include a Rhyn- 

 chodemus and a Bipalkim. The latter, however, is almost 

 certainly introduced, and possibly also the former, the speci- 

 mens of which appear to be identical with an Australian 

 species. The majority of the species of Land-Planarians seem 

 to be very closely related to Australian forms, but distin- 

 guishable by some slight difference in colour or pattern. 



The most interesting addition to the cryptozoic fauna which 

 I have to record, however, is an indigenous Land-Nemertiue, 

 quite distinct not only from the Australian species {Geo- 

 nemertes australiensis^ Dendy *) but also from any other 

 previously described form. This will be described in the 

 sequel under the name of Geonemertes novc^-zealandice, and 

 its discovery brings the total number of known terrestrial 

 Nemertines up to six. 



1 will now give a list of the cryptozoic animals above 

 referred to, together with information sufficient for identi- 

 fication of the new forms. Fuller details will, I hope, be 

 published in the ' Transactions of the New Zealand 

 Institute.'
