Gloucestershire, and Northamptonsliire mentioned in Ms interesting 

 paper, and I obtained many of the fossils given in his list. Several of 

 these from the neighbourhood of Grantham I sent, at the time, to my 

 friend Dr. Lycett, and he stated that although the greater number 

 were new to him yet the rest were species decidedly belonging to the 

 Inferior Oolite ; and Mr. Sharp, with whom, on a future occasion, I 

 examined the neighbourhood of Northampton, and who is thoroughly 

 conversant with the geology of the district, agreed with me in classing 

 the ferruginous Oolite overlying the Lias with the Inferior Oolite. 

 Amongst other fossils obtained there of a decidedly Inferior Oolite 

 fades I found a specimen of Pygaster semunlcatus which has not yet 

 been recorded higher than that formation, and is common enough in 

 the peagrit and pisolite near Cheltenham. Mr. Morris gives it in his 

 list of fossils near Northampton, as well as Hyhocly-pus agariciformis. 

 If these were not considered sufficient to prove the position of the 

 rock in which they occur, the other shells I obtained associated 

 with them, and a still larger number named by Mr. Morris, are decisive 

 upon the point, as far as palaeontological evidence goes. As there is also 

 a clear ascending section from the Lias to the Great Oolite, the inter- 

 vening strata may, therefore, be more reasonably placed with the In- 

 ferior Oolite, although there are certain lithological differences and a 

 large increase of ferruginous matter in the Midland district, when com- 

 pared with the same formation in Gloucestershire. It is not a matter 

 of much consequence, but I think it due to myself to state that, after 

 a careful comparison of the sections and fossils of the outer escarpments 

 of the Cotswolds with those of Lincolnshire, and Northamptonshire, I 

 had held from the first, since the year 1850, that a certain portion 

 of the Oolites of the Midland Counties belonged to the Inferior Oolite, 

 with which they will now probably be again and finally classed.

ELEPHAS MERIBIONALIS IN THE NOEWICH CRAG. 



Sir, — ^I was sui-prised on again seeing Mr. Eoper's collection at 

 Lowestoff, to find that it did not contain one single specimen of an 

 elephant's tooth, and that all the Mammalian remains were from, 

 as he described it, the (^oprolite bed beneath the Coralline Crag, and 

 none at all from the Eed Crag. The collection had been removed 

 from West Tofts, near Brandon, where I had seen it five years ago ; 

 but there was no ground to suppose any specimen had been lost, for 

 Mr. Eoper showed me a MS., in which he had carefully figured all 

 the mammals, with a coloured section of the strata at Sutton. The 

 lowest of these was the bed from which he had taken an old shed 

 tooth of a Mastodon, and three fragmentary portions of others, to- 

 gether with the basal part of a deer's horn, and a beautiful and per- 

 fect molar of a pig. Above this was the Coralline Crag, and then 

 the Eed Crag, from which, he said, he had obtained no Mammalian 

 remains whatever. 



I am very sorry to have misled Mr. Fisher by my having con- 

 founded, as it appears, I must have done, this tooth of a Mastodon,
