ciently from the N. S. Wales specimens used by Prof. Owen for the 

 completion of his memoir on T. carnifex in the Philosophical Trans- 

 actions as to suggest specific separation. Should this view be 

 accepted, he proposes to restrict the name T. carnifex, Owen, to the 

 portion of the upper jaw figured and described from the original 

 Lake Colungulac example, whilst for the N. S. Wales specimens he 

 proposes the name T. Oweni, M'Coy. 



Five species of Trilobites are figured, including PJiacops caudatus, 

 Brong., and Homalonotus Harrisoni, M'Coy. The former is one of 

 our most typical Upper Silurian species, and appears to run through 

 as many varieties, at the Antipodes, as in Britain. The latter is a 

 representative of its English and American ally, H. delpJiinocepha- 

 lus, Green. 



Passing to fossils of Tertiary age, we are introduced to the Austra- 

 lian analogue of another British shell, Nautilus (Aturia) zic-zac, Sow., 

 of the London-clay. The Victorian individuals from the Oligocene and 

 Pliocene beds of Port Philip Bay so closely resemble the compressed 

 variety of the above species [Nautilus aturia, Basterot), that Prof. 

 M'Coy has merely given to them the varietal name Australis 

 (N. (Aturia) zic-zac, Sow., var. Australis, M'Coy). Of numerous genera 

 which have almost disappeared since the close of the Mesozoic Epoch 

 is the genus Pleurotomaria. It is represented in European Tertiary 

 strata by two rare species, F. Sismondai, Goldf., and P. concava, 

 Deshayes, and in the living state by two still rarer, F. Adansoniana, 

 and F. Quoyana. To these Prof. M'Coy has had the extreme good 

 fortune to add a third Tertiar}^ species, F. Tertiaria, from a lime- 

 stone interstratified with Basalt on the Moorabool Eiver, at Maud. 



Prof. M'Coy has already made known two Tertiary species of 

 Trigonia (T. semiundidata, M'Coy, and T. acuticostata, M'Coy), and 

 now adds another, T. Howitti, a larger, thicker, and stronger shell 

 than either of the former or the living species. It was found in 

 sandy marl at the entrance to the Gippsland Lakes. 



Two other forms call for special notice, one, Cuculicea Corioensis 

 M'Coy, a very common shell in certain of the Victorian Tertiary 

 beds. It is distinguished from the recent species by its much 

 greater gibbosity, thicker shell, etc., and has for nearest allies in the 

 fossil state a New Zealand Tertiary species, C. ponderosa, Hutton, 

 and C. crassatina, Lamk., of the French Upper Eocene. The second 

 form to which we would draw attention is the Cyprcea avellanoides, 

 M'Coy, an almost exact representative of the European Trivia 

 avellana. Numerous other species are described to which less 

 general interest is attached, although each forms a welcome addition 

 to Australian Palaeontology. K. E. Jun.
