IN this interesting and important communication the learned 

 Professor of the Paris Museum brings to notice a nearly com- 

 plete lower jaw, recently obtained from the Miocene of St. Gaudens, 

 belonging to the large Anthropoid Ape known as Dryopithecus. 



This Ape, it may be well to mention, was previously known 

 mainly by a very imperfect lower jaw obtained many years ago 

 from the same deposits, and described by the late Edouard Lartet. 

 Owing to the imperfection of that specimen, it was considered that 

 the Dryopitheque had an extremely short symphysis to the lower 

 jaw, and consequently that it was more specialized, and came nearer 

 the human type than any existing Ape. The comparatively early 

 geological horizon in which the remains of this Ape are found 

 rendered its presumed specialization a very remarkable circumstance. 



The new specimen has, however, proved that the creature was, as 

 might have been expected from a priori considerations, in reality the 

 most generalized of all the Man-like Apes. This is, indeed, rendered 

 very clear by the four lower jaws represented in the plate accompany- 

 ing Prof. Gaudry's memoir; and it will be seen from these figures that 

 there is a very gradual diminution in the length of the symphysis 

 of the lower jaw as we pass from the Dropitheque to the Gorilla, 

 Chimpanzee, and, finally, Man. The long symphysis of the fossil 

 form allies it with the lower Baboons and Monkeys ; and we thus 

 see that the Dryopitheque now definitely takes that place in the 

 family Simiidce which we should have assigned to it from its geological 

 horizon. The relegation of this Ape to a low position induces the 

 Professor to withdraw his suggestion that the problematical facetted 

 flints of the Miocene of Thenay were its handiwork. E. L.

A SKETCH of the Natural History of Yarmouth and its 

 neighbourhood, by C. J. and [Sir] James Paget, was published 

 in 1834. That work contains but a brief reference to the geology ; 

 for, excepting in some controversial papers on recent physical 

 changes by J. W. Kobberds and E. C. Taylor, the district had 

 up to that time received but little attention from geologists. The 

 interest of the geology is indeed to a large extent furnished by the 

 cliff-sections of Kessingland, Pakefield, and Corton. Accounts of 

 these were subsequently published by Trimmer, Gunn, AVood and 

 Harmei', Prestwich, and others ; and in 1884 a detailed section by 

 Mr. Blake was published by the Geological Survey (see Geol. Mag. 

 April, 1885, p. 180). 



Mr. Blake now gives full particulars of all the strata exposed in
