more abruptly. The peripharyngeal aperture is situate at about the junction of the 

 middle and posterior thirds of the body and the genital aperture nearer to it than to 

 the posterior end. 



The eyes are, as in G. alha, very small and difficult to make out. 



Geoplana (Coenoplana) sangiiinea w^as very imperfectly described by Moseley as 

 follov^rs : — " Closely resembles C. Coerulea, with the exception that it is coloured of 

 a uniform light red, vphich is lighter upon tlie under surface of the body. Actual 

 length when living 7 cm.; breadth 4 mm., Parramatta, near Sydney. Amongst 

 earth at the roots of a Eucalyptus stump." (hoc. cit.) 



It seems probable that Fletcher and Hamilton's G. rnbiciinda* is identical with 

 G. sanguinea, a conclusion at which I understand Mr. Fletcher has himself now 

 arrived. My G. alba is also evidently closely related to G. sanguinea and may have 

 to be considered merely as a variety of that species. 



G. sanguinea (as represented by the Castlemaine specimens), G. rubicunda and 

 G. alba all agree in the general shape of the body, in the position of the apertures 

 and in the curious indistinctness of the eyes. 



The Castlemaine specimens of G. sanguinea are all markedly smaller than the 

 average size of G. alba, but Moseley's examples seem to have been of about the same 

 size as the latter. 



3, Geoplana spenceri, Dendy. 



This species has again been met with by Professor Spencerf on the occasion of 

 the Field Naturalists' expedition to the Yarra Falls, in a locality intermediate between 

 the Upper Yarra district and Walhalla, whence it had been previously recorded. 

 Though extremely abundant in these parts it does not seem to occur in other localities, 

 so that its distribution appears to be curiously limited in extent. 



4. Geoplana carulea, Moseley. 

 (PL IV., Fig. 7.) 



In my previous memoir on the Victorian Land Planarians I recorded this species 

 from Croajingolong, where it was collected by Professor Spencer. Since then 

 I have only met with a single specimen and that in a somewhat remarkable
