1. "Notes on some Fossils, chiefly Mollusca, from the Inferior 

 Oolite." By the Rev. G. F. Whidborne, M.A., F.G.S. 



The fossils described by the author are, with the exception of 

 some in the British Museum and a few of his own collecting, in the 

 collections from the Inferior Oolite which enrich the Bristol Museum. 

 Several of the species are new ; of these there are Ostrea 2, Grtj- 

 phcea 3, Exogyra 1, Pecten 4, Harpax 1, PUcatula 1, Plaeuna 1, 

 Gervillia 3, Pinna 2, Lima 11, Mytilus 2, Area 3, Nucula 1, 

 Cardium 2, Cypricardia 1, Myoconcha 2, Astarte 1, Opts 1, 

 Thracia}, Pholadomya 3, My aches I, and Terebratida 2, besides 

 one or two more that are doubtful. 



2. " On some Fossil Sponges from the Inferior Oolite." By 

 Prof. W. J. Sollas, M.A., F.0.S. 



Some fossil Sponges have been described from the Inferior Oolite 

 of the continent ; but hitherto none have appeared in the lists of 

 fossils from this formation in British localities. The collection of 

 Sponges described by the author was made by the Rev. G. F. 

 Whidborne. The author described 11 species (6 of which he iden- 

 tified with those already described from continental localities) be- 

 longing to 9 genera, and concluded his paper with some general 

 remarks. These Sponges are calcareous, but are considered by the 

 author to have been originally siliceous, replacement of the one 

 mineral by the other having taken place as already noticed by him. 

 The beds in which these Sponges are found bear all the appearance 

 of being comparatively shallow-water deposits. 



3. " On the Dinosaurs from the Maastricht Beds.'* By Prof. 

 H. G. Seelev, F.R.S., F.G.S. 



In this paper the author described five fragmentary bones arranged 

 among the remains of Masasaurue in the Van-Breda collection when 

 received by the British Museum, One of these is a femur want- 

 ing the distal end, and worn at the proximal extremity, 11 1 inches 

 long, with an average thickness of about 1| inch, and " remarkable 

 for its slender form, its superior bow-shape curvature, the lateral 

 compression of the proximal articulation, and the extent to which 

 it is directed inward, for the trochanter, which is separated from the 

 proximal end of the bone in front, and for the proximal position and 

 small size of the lateral trochanter." For the species indicated by 

 this bone the author proposed the name of Mec/alosaarus Bredai. 



Another femur, slightly imperfect at its articular end, 19| inches 

 long, has a remarkably straight and strong shaft, subtriangular at 

 the proximal end, subquadrate in its lower part, and bearing the 



lateral trochanter in th« middle, and has the nroximal and distal
