 Northern Seas. Southern Seas. 



Norwich Crag 

 Red Crag 

 White Crag . 



According to Clement Reid (1890, p. 6), " The ' Nodule Bed ' 

 seems to be nearly co-extensive with the Red Crag, and probably also 

 with the Coralline Crag, though often too thin to be of any economic 

 importance. ... A large proportion of the [mammalian] fossils appears 

 to belong to a period somewhat earlier than the Crag, though still 

 truly Pliocene, ..." 



According to the same author (op. cit., p. 139), "The most probable 

 view seems to be that the two deposits [Chillesford, Weybourn] 

 are synchronous, and that the Chillesford Clay passes laterally into 

 the Weybourn Crag, or, at any rate, that the Weybourn Crag is 

 equivalent to the upper part of the Chillesford Clay." 



During the writer's visit to Cromer, accompanied by Mr. J. Reid 

 Moir, he had the good fortune to examine the remarkable 

 collection made by Mr. A. C. Savin. The writer is indebted to Mr. 

 Savin for a letter, dated 21st November, 1921, together with notes, 

 from which the following quotations are taken. 



Notes and Observations by Mr. A. C. Savin : Quoted with 

 Slight Modifications and Omissions. 



" I enclose a list of the Forest Bed vertebrates up to date, but there 

 are still several forms to add later on. Mr. M. A. C. Hmton has a 

 lot of my smaller things which he is now at work on. These include 

 new voles, hare, hedgehog, etc. He hopes to publish the result 

 shortly. One interesting addition is Felis spelcva, which is new to 

 the Forest Bed. 



" I have made a few notes relative to the horizon of the various 

 species, from which you will gather that I do not think it possible 

 to assign any particular level to any one species. I record in my 

 catalogue the exact locality of each specimen, but cannot find a 

 hard and fast horizon for any one species. 



" Prohoscidea. — At Mundesley some of the large bones of ElepJias 

 meridionalis in the ' Gunn Collection ' Avere gotten out of the ' Pan ' 

 at a high level, i.e. 4 feet above the beach ; on the other hand, others 

 were obtained from a deep low or scour half-way down the beach, 

 quite 15 feet lower down, and so on with most of the other animals. 

 Elephas meridionalis is found generally all along the coast, but mainly 

 at Mundesley and Bacton in the ' Pan ' (gravel with oxide of iron) at 

 the base of the cliff, also in the ' lows ' or places scoured out half- 

 way down the beach, in a greenish sandy clay. I do not think any 

 definite horizon can be given ; this applies also to antiquus and 

 primigenius. 



" No Mastodon remains have ever been found on the Norfolk 

 coast ; they only occur in the Red Crag of Suffolk and the Norwich
