NOTES ON HAND PLANARIANS. 421 



Australia, collected by Professor Spencer, Mr. Alexander Morton, 

 Mr. G. C. Officer, Mr. L. J. Balfour, and Mr. Thos. Steele. Some 

 of these species are new to science and of exceptional interest, and 

 they will be described by me in another place in detail. 



The total number of species now known from Tasmania is thus 

 brought up to nine, one of which is also represented by a very 

 distinct variety. These species are as follows : — 



1. Geoplana Walhalla, Dendy (also found in Victoria, but rare 

 in both colonies). 



2. Geoplana Tasmaniana, Darwin. — This species lias been ob- 

 tained in large numbers, and is now re-identified for the first time 

 since its original discovery by Darwin on the occasion of the 

 memorable voyage of the Beagle. It was, I believe, the first land 

 planarian ever described from Australasia. 



3. Geoplana Duinensis,n. sp. — A very large and handsome new 

 species, apparently with considerable anatomical peculiarities. 



4. Geoplana Lucasi, Dendy. — A large species, also found in 

 Victoria in elevated country in the north-east of the colony. 



5. Geoplana Mortoni, n. sp. — A handsome and well-marked new 

 S2Decies, though evidently related to the Victorian and South 

 Australian G. Fletcheri. I have named this species after Mr. 

 Alexander iMorton, from whom I first received it. 



6. Geoplana munda, Fletcher and Hamilton. — This pretty little 

 species, so abundant in Victoria, has been brought to light in large 

 numbers in Tasmania by the investigations of Professor Spencer. 



7. Geoplana Adce, Dendy. — A slight variety of this well- 

 known Victorian species was recorded from Tasmania in my last 

 paper on the subject I have since received three specimens of 

 another very distinct variety, for which I propose the name 

 Geoplana Adee, var. fusca. They were collected by Professor 

 Spencer at Lake St. Clair. 



8. Geoplana varieyata, Fletcher and Hamilton. — An unmistak- 

 able specimen of this very beautiful species was also collected by 

 Professor Spencer. It is remarkable that, although a common 

 Queensland and New South Wales species, it lias not yet been 

 recorded from Victoria. 



9. Geoiilana typhlops, n. sp. — In my notes communicated to the 

 Hobart meeting of this Association I described specimens of what I 

 took to be uncommon Victorian Geoplana alba, Avhich were obtained 

 from Mount Wellington. I pointed out at the time, however, that 

 I could find no eyes, and that I should much like to examine fresh 

 material. I have now received living material of the same species 

 from Mr. Balfour, and more spirit material from Mr. Morton and 

 Professor Spencer, collected in various parts of Tasmania ; and the 

 eyes appear to be undoubtedly absent. This is a very remarkable 

 fact, for the eyes are distinctly present, albeit small, in the Victorian 

 G. alba, and also in specimens of G. alba which I have obtained 

 from New Zealand. "Wliy they should be absent in all the
