28 ADDITIONAL OBSERVATIONS ON 



described by Professor Moseley. Since then it has been found in various parts of 

 England and also in Sydney,* and still more recently, as I have already noticed, Mr. 

 Fletcher has recorded its occurrence at Eltham, and likewise in Samoa. Good figures 

 of this interesting Planarian are given by Bell in his "Note on Bipalinm kcwcnse, 

 and the Generic Characters of Land-Planarians."t 



Concerning Rhynchodcinus and Bipalinm I have nothing further to add, and we 

 may pass on to the systematic observations on the 20 species of Geoplana. As the 

 present memoir is merely a continuation of my earlier paper "On the Victorian 

 Land Planarians," published in the Transactions of this Society for 1890, I have not 

 thought it necessary to give constant references to that paper, to which I would 

 refer the reader for further information and references. 



1. Geoplana alba, Dendy. 



This is one of the most widely distributed and abundant of our Victorian 

 Land Planarians. Since the publication of my description and figures Professor 

 Spencer has recorded the species]; — on the occasion of the Field Naturalists' 

 Expedition to the Yarra Falls — and has figured two specimens which are of a rather 

 darker colour than usual and thus approach G. saiigiiinea. As already noted in my 

 original description the species varies a good deal as to the depth of colouration, from 

 almost pure white to peach-coloured or yellow flesh. I may add that the eyes are 

 very small and difficult to make out. In addition to the localities already mentioned 

 I have now obtained the species from Croydon, Fern-Tree Gully, Ballarat (abundant 

 under stones close to the edge of the lake, Mr. Avery), and the Upper Wellington 

 River. 



2. Geoplana sanguinca, Moseley. § 



This species has not hitherto been recorded from Victoria, but I have now 

 received seven specimens collected by Mr. T. S. Hall, M.A., at Castlemaine, under 

 fallen bark and stones. The specimens were received by me in alcohol, with the 

 following note as to the colours of the living worm : — " Rich Indian red above, 

 paler below." The specimens (in spirit) are about 25 mm. long, and 4 mm. 

 broad, much flattened on the ventral surface but pretty strongly arched on the dorsal. 

 The anterior end of the body tapers off gradually, the posterior end terminates much
