78 NOTES ON TASMANIAN CONCHOLOGY. 



responded exactly to Wood's description, and was, I believe, 

 rightly identified. It is certainly not a mollusc, but a 

 planarian. My friend, Mr, T. Whitelegge, considered that it 

 is I'Yohablj Polycelis australis, Schmarda. It bad better be 

 excluded from tlie molluscan catalogue. 



The existence of the order Heteropoda in Tasmanian 

 waters has been overlooked by Tate and May. The 

 occurrence in Bass Straits of a species of Fie,oboida is noted 

 by Maedonald. Trans. Eoy. Soc, Edinburgh, xxiii., 1862, p. 

 5; pi. i., ff. 1-4. 



EissoiNA GEETRUDis, Ten. Woods, Pro. Eoy. Soc, 1876. 

 p. 146. This species approaches R. elegantula, Angas ; whether 

 or not intermediate forms unite these two, I leave to the 

 decision ot those better acquainted with the species. The 

 illustration published by Tryon is very bad ; possibly it was 

 based on a different species. I add a drawing of the type 

 specimen in the Tasmanian Museum. 



Ctclostrema weldii, T. Woods. It is generally admitted 

 that this and C. australe, Angas are synonymus. Tate and 

 May regard the latter as having priority, but Pritchard and 

 Gatliff award it to G. weldii. As a matter of fact, C. weldii 

 was published Feb. 27th, 1877, and C. australe on June 1st, 

 1877. 



Teochtjs eingens, Menke iischer, in the Coquille 

 Yivautes, Troque, 1879, p. 214, notes this species from " He 

 Yan Diemen." It is not included in anj Tasmanian 

 catalogue.
