remains of these two species have also been found by Dr. Wehring 

 near Westeregelt, associated with those of Ehinoceros, Horse, 

 Marmot, Lemming, etc. 



Split bones, worked fragments of horns, and flint implements 

 were also found in this cave. The dolomitie d'etritus, heaped in 

 form of a terrace before the cave, is full of bone splinters and broken 

 antlers of Eeindeer, without any traces of having been gnawed by 

 Hycenas. — Count M.

THIS important contribution to Belgian geology is endorsed 

 " Extracted from the Annals of the Malacological Society of 

 Belgium, vol. ix. 1874," but was published separately late in 1876. 

 It forms the first instalment of a series of publications in course of 

 preparation, constituting a monograph of the Belgian Pliocene Fora- 

 minifera. The second instalment is on the eve of publication. 



The chief points to which the author draws attention in the 

 portion before us are: — 1st. The conditions under which the Pliocene 

 deposits of W. Eui'ope were formed ; and 2nd. The alterations which 

 those deposits have subsequently undergone. 



The Miocene Period is unrepresented in the Anglo-Belgian area 

 by any deposit ; the subsidence of that area initiating the Pliocene 

 Epoch. The gulf thus formed was partly occupied by mollusca, 

 etc., migrating from the Vienna Miocene Basin (then beginuing to 

 shallow) through Silesia and N.W. Gei'many. 



The earliest deposit is characterized by Panopoia Menardi ; it is a 

 slightly clayey sand, of a dark olive-green colour from the abundance 

 of glauconite grains. The fauna denotes water of 100 to 200 feet in 

 depth, about two-thirds being Gasteropods. Partly synchronous 

 vv^ith the later beds of this zone are sands charactei'ized by Pectun- 

 culus pilosns, equally glauconitic but less clayey, and with a littoral 

 fauna, two-thirds of which are Lamellibranchs. Of slightly later 

 date are the Gravelly Sands of Diest and Antwerp, completing the 

 Lower Sands of Antwerp, which have no British equivalent excejjt 

 the traces of questionable age on the Kentish Downs. The synonymy 

 of this part of the series is treated at considerable length by the 

 author, resulting in the following condensed statement : —
