Limb-bones.—Since the humerus is known in Hylœsaurus (?), Omosaurus, and Stegosaurus, it is quite easy to compare the humerus of our new species with that of the other genera mentioned. Whether the shaft is hollow as in Omosaurus or solid as in Stegosaurus, cannot be ascertained without breaking the specimen; the outline of the new humerus is, however, that of Omosaurus, not that of Stegosaurus.

Zoarium free, unilaminate, the back divided by somewhat wavy, shallow, slightly diverging furrows into long narrow strips which correspond with the lines of zoœeia; these strips are occasionally crossed by very shallow depressions or furrows corresponding to the boundaries of individual zoœcia.

Through the kindness of Mr. Walter Egginton I have recently had an opportunity of studying an interesting series of Crustacea from the Coal - measures of Coseley, near Dudley. Most of the specimens can be referred, with more or less probability, to the division Syncarida, which includes the living Anaspides and its allics, and among them are some which I regard as representing a new genus. Although the fossils, which are contained in nodules of clayironstone, often show very minute details of structure in a beautifully perfect state, it is just those features most important from a morphological point of view that are most frequently obscured. There are many essential points that cannot be determined from the material at my disposal, and the conclusions drawn as to the systematic affinities of the genus must therefore be regarded as to some extent provisional.

In the course of the preparation of the second part of the Catalogue of the Marine Reptiles of the Oxford Clay in the Collection at the British Museum, it has been necessary to examine in detail the structure of the skull and mandible of the Pliosaurs, especially of Peloneustes philarchus, several excellent specimens of which are included in the Leeds Collection. In the course of this examination several peculiarities have been observed, which on the one hand tend to reconcile the conflicting views as to the structure of the skull roof that have been put forward, and on the other serve to correct the interpretation of the elements of the mandible given in the first part of the Catalogue.

The more exact investigation of the distribution and mode of occurrence of Neolithic remains has received a much needed stimulus from the publication of Professor Brögger's memoir dealing with the position of the strandlines in South-Eastern Norway during the stone age of that country. It has been clearly demonstrated in this important work that it is possible to distinguish, even in the relatively short-lived Neolithic culture, certain phases of chronological value, and to correlate these phases, by means of the distribution of the implements which characterize them, with the successive stages in the elevation of the land which affected Scandinavia in postglacial times. It has become clear, therefore, that the careful registration and description of Neolithic relics may lead to the most important scientific results, and it will be realized by all who indulge in archæological collecting that an exact determination of the locality of any find and of the relations it bears to the superficial deposits of the neighbourhood, more especially to the old shorelines which border the coasts of the British Isles, is of the utmost importance.
