of Australia. The occurrence of these beds in a longitude east of 

 similar ones in Australia, " proves one more link to the union of 

 these beds with the great Tertiary formation of New Zealand." 

 In the nomenclature of Professor P. Martin Duncan the Table Cape 

 beds will be Lower Cainozoic. Mr. Woods describes the new 

 species of Mollusca in detail. E. E., Jun. 



II. — On a New Crinoid from the Cretaceous Formation of the 

 West. By George Bird Grinnell. American Journal of Science 

 and Arts, No. 67, vol. xii. (July, 1876), pp. 81-3, pi. 4. 



UNTIL the discovery of the unique fossil, described in the above 

 paper, by Professor 0. C. Marsh, Crinoids from the American 

 Cretaceous were unknown. The new form, to which the name of 

 Uintacrinus socialis has been given, belongs to the Astylidce, or free 

 Crinoids, and is allied to the genus Marsujpites, Miller. It differs 

 from the latter in the form and arrangement of its plates, and in 

 having apparently ten arms; it may be the type of a new group. 

 The individuals are found associated together in considerable 

 numbers, hence the specific name. JJ. socialis was first discovered 

 by Professor Marsh in the Cretaceous of the Uinta Mountains, 

 associated with the scales of a Beryx and Ostrea conjesta, Conrad. 

 Specimens have since been discovered in the Kansas Cretaceous 

 beds, associated with Odontornithes, Pterodactyles, and Mosasauroid 

 reptiles. Mr. Grinnell gives a detailed specific description.

III. COTTESWOLD NaTURALISTS' FiELD ClUB. 



DUPING the past two years the Members of this Club have been 

 as active as ever, and the results of their researches — almost 

 entirely geological and archasological — form a large and well- 

 illustrated series of papers. The Addresses of the President, Sir 

 William Guise, contain an epitome of the work done, and the 

 records of those pleasant field meetings for which this Club has 

 always been celebrated. 



Excursions have been made to Newent, Bath, Eadstock, Farring- 

 don in Berkshire, Chepstow, Symonds Yat (Ross and Monmouth), 

 Pendock, Portskewet, Caldicot Castle, and Caerwent. And it is 

 needless to say that under the able guidance of Dr. Wright, the Rev. 

 W. S. Symonds, Messrs. Etheridge, C. Moore, Lucy, McMurtrie, 

 and others, the many points of geological interest met with on these 

 several excursions have not been neglected. 



The printed papers include one on a Bed of Fuller's Earth at 

 Whiteshill, near Stroud ; and another on the Angular Gravel of the 

 Cotteswolds, by Mr. Witchell. This Angular Gravel, which occurs 

 on the slopes of the Oolitic escarpments, was at one time considered 

 to be the remains of sea-beaches — a view now happily abandoned. 

 It consists of Oolitic detritus, and is evidently the result of subaerial 

 denudation. Mr. Witchell considers that the formation probably 

 commenced before the river-gravel was laid down ; and that perhaps 

 the period to be assigned to its commencement is that of the
