390 Reports and Proceedings. 



on the east side of Derwentwater, between Keswick and the Vale of 

 St. John, in the Vale of St. John, in Matterdale, in Eycott Hill, 

 between UUeswater and Haweswater, and in the neighbourhood of 

 Shap. In the Borrowdale section the sequence of the rocks is given 

 by the author as follows : — Eesting on the Skiddaw slates there are 

 (1) a felspathic trap ; (2) a great series of ashes, breccias, and amyg- 

 daloids, often showing slaty cleavage and worked as slates, but with 

 several intercalated bands of trap; and (3) a second trap. This 

 appears to be a normal section, and is repeated, but diversified by 

 the results of folding and faults in the other localities described by 

 the author, except that in the Vale of St. John the true slaty series 

 seems to be entirely wanting. 



2. " Observations on some Vegetable Fossils from Victoria." By 

 Dr. Ferdinand von Miiller and E. Brough Smyth, Esq., F.G.S. 



Mr. Smyth stated that the fossils, of which specimens were for- 

 warded by him, were obtained in one of the deep leads at Haddon, 

 near Smythesdale. No leaves have been obtained from the bed, which 

 consists of a greyish-black clay ; the fruits and seed-vessels were 

 obtained about 180 feet from the surface, and represent a flora not 

 very dissimilar to that now characterizing some parts of Queensland. 

 The specimens sent include the fruits of a supposed new genus of 

 Coniferee, described by Dr. von Miiller under the name of Spondy- 

 hsiroius. It is most nearly allied to Solenostrohus (Bowerbank), but 

 its five valves are not keeled. The columella forms the main body 

 of the fruit ; and the seeds are apparently solitary. The species was 

 named Spondylostrolus Smythii. The remaining specimens consisted 

 of a solitary fruit of a genus of Verbenace^ ; an indehiscent com- 

 pressed fruit, probably belonging to the proteaceous genus Helicia ; 

 a nut nearly allied to the preceding ; a large, spherical, unilocular, 

 three-seeded nut with a thick pericarp, perhaps from a Capparideous 

 plant ; a five-valved capsule of an unknown genus ; and fruit- 

 valves of three other plants, probably belonging to the Sapindaceee, 

 and perhaps allied to Cupania. One of the last may belong to the 

 Meliciaceous genus Dysoxylon. Dr. Miiller considered that these 

 remains indicate a former flora analogous to that of the existing 

 forest-belt of Eastern Australia. 



3. "Note on some Plesiosaurian Eemains obtained by J. 0. 

 Mansell, Esq., F.G.'S., in Kimmeridge Bay, Dorset." By J. W. Hulke. 

 Esq., F.E.S., F.G.S. 



The remains described in this Note represent two new species of 

 Plesiosauriis. The dorsal vertebras of the first species are distin- 

 guished by extremely short centra, with hollow articular faces. 

 The antero-posterior diameter of four centra ranges between 1 and 1*3 

 inch, the transverse horizontal diameter between 4 and 4-6, and the 

 vertical between 3-8 and 4 inches. For this Plesiosaur the author 

 proposes the specific name of P. Irachistospondylus. 



The other species, of which the greater part of the spinal column 

 and portions of the breast and pelvic girdles and limbs are pre-
