irregularly, branches hollow, rarely oncrnsting, eolls inflated, 

 irregular, with large avicularium at each side of mouth, pro- 

 bably a socket for a vibraculuui above. 



2. Hemipatacjus Forhesii Duncan. — Ann. Nat. Hist., vol. 

 xiv., p. 1(35. — i regard the above two fossils as very charac- 

 teristic of the upper (so-called Miocene or lower Pliocene 

 beds of Australia.) They are never found mingled with the 

 lower fossils, except in intermediate beds, and then only spar- 

 ingly, as in the present case. 



3. Pecfeii laticosfatiis Quoy. — This shell is still a common 

 existing species in New Zealand, from whence I have received 

 specimens ; I believe from Dunedin or Invercargill, Middle 

 Island. 



4. Dentalium Kicksii Nyst. — This shell is described in 

 Nyst's Coquilles, <tc.,des terrains tertiaries de la Belgique. As 

 the work is scai'cely accessible to Tasmanians, I give his 

 diagnosis, D. testa ferefi, subarcitata, lougitudinaliter striata, 

 striis irref/idariter dispositU. He adds that tliis fossil is quite 

 distinct from B. striatum Sow. of the London clay, though 

 somewhat like D. gramle and D. Bouei of Deshayes, Paris 

 basin. The ends of all the species seen were constantly broken. 



Dentalium long and narrow, finely streaked lengthwise. Striae 

 vai*iable in number and position, and sometimes a vacant space 

 or groove instead, sometimes irregularly placed between 

 slightly elevated narrow and sharp ribs, prolonged along whole 

 surface, and variable in number. Numerous transverse stria) 

 indicating lines of growth. 



6. Waldlieimia. — This species was described by me in the 

 Transactions of the Adelaide Philosophical Society, and 

 figured by that Society in 1866. I find the synonym W. 

 macropora M'Coy attributed to a specimen in the collections of 

 the Victorian Geological Survey. It is very common in the 

 Murray beds, and in the Geelong miocene. 



7. Ehynchonella hicida M'Coy. — I think the species found at 

 Table Cape will be found identical with R. lucida of M'Coy, 

 It is common in the Geelong beds, and though probably 

 now an extinct species, one like it occurs in the tertiaries of 

 Spain in the glacial deposits, in the Norwich Crag (pliocene), 

 and is still living in Australia: that is, B. psittacea Sowerby. 



8. CuccuUoea concamerata Eeeve. — Very common in No. 2, 

 Australia, and many specimens here. Living at present in 

 the Mauritius seas, Nicobar, China. Figured by Sowerby, 

 Gen. Char. Shells, Vol. 1, and in Woodward's manual. 



9. Cjiproea eximia Sow. — This shell was described by 

 Sowerby in Strzelecki's New South Wales, &c., from a speci- 

 men said to have been found in a well at Franklin village, 

 130 feet below the surface. This, I presume, is near Laun-
