Prof. Owen on Australian Fossils. 397 



4. " On an Outlier of Lias in Banffshire." By T. F, Jamieson, 

 Esq. In a letter to Sir R. I. Alurchison, V.P.G.S. 



In a cutting of the Banff and Turriff Railway, about four miles to 

 the north of Turriff, there has been exposed a thick mass of tenacious 

 blue clay, containing Ammonites, BeJemnites, Gryphcex, Plagiosto- 

 mata, and other fossils of Liassic character. 



The author explained his reasons for regarding this clay as being 

 a fragment of the Lias in situ, and noticed the interest belonging to 

 it as being perhaps the most eastern Liassic outlier in Scotland. 



5. " Notes on a Collection of Australian Fossils in the Museum 

 of the Nat. Hist. Soc. Worcester." By Professor Owen, F.R.S., 

 F.G.S. 



By the examination of a series of mammalian fossils sent from 

 the Condamine River and Darling DoMns, and now in the Worcester 

 Museum, and of casts of the cranium, upper jaw, and teeth of 

 Macleay's " Zygomaturus," communicated by the Trustees of the 

 Sydney Museum, Professor Owen has been able to demonstrate that 

 this cranium belongs, as he suggested in a paper lately read before 

 the Society, to his genus Nototherium, and to the species which he 

 had dedicated to the late Sir T. Mitchell. A smaller species, pro- 

 visionally named Nototherium incrme, was also established by Pro- 

 fessor Owen on some of the specimens examined ; but he thinks it 

 not improbable that with additional materials it might be found that 

 these two forms may represent the male and female of one species. 



6. " On the Occurrence of some Tertiary Fossils at Chislet, near 

 Canterbury." By John Brown, Esq., F.G.S. With Notes on the 

 Species, by G. B. Sowerby, Esq., F.L.S. 



These fossils were found by Mr. Brown in a small exposure of sand 

 and clay beds, in a garden on a hill-side in the parish of Chislet, 

 Kent. The beds would appear, according to Mr. Prestwich's sec- 

 tions of that county, to belong to his " Lower London Tertiaries ;" 

 but of the 36 species of Shells, Cirripeds, and Forarainifera met 

 with — lo are forms found also in the Crag; 9 are English Lower 

 Tertiary forms ; 2 are Belgian Tertiary forms ; and 4 are new species. 



7. " On the Fossil Crustacean found by Mr. Kirkby in the Mag- 

 ncsian Limestone of Durham, and on a new species of Amphipod." 

 By Spence Bate, Esq. Communicated by Dr. Falconer, F.G.S. 



In this paper Mr. Bate described a new recent Amphipodous 

 Crustacean, which he believes to repi^esent some of the fossil crus- 

 tacean remains lately described by Mr. Kirkby in the Society's 

 Journal, under the name of Prosoijoniscus prohlcmaticus, 



8. " On Euryptcrus." By J..W. Salter, Esq., F.G.S. 



The author gave a history of what is known about this genus, — 

 described several new or little known species, — and observed that 

 the range of the genus is confined to the Ludlow, Devonian, and 

 Lower Carboniferous strata. The new species described were — 

 Kurypterus Symotidsii, E. pyc/maus, E. meyalops, E. acuminatus, E. 

 linearis, E, ubbrevialus, and E. Aquila-chartacea. E. Hcouleri, Hib-
