SUPPLEMENT TO THE BRITISH 



Sutton, where specimens from one line in length to upwards of five inches may be 

 collected. 



- T. grandis is the most abundant of all the Tertiary species in England, France, 

 Belgium, and Germany. It is found also in Italy and Spain. A shell- or Terebratula- 

 breccia, detached by Captain Brome from a hewn block that constituted part of an old 

 Moorish fort at Gibraltar, and given by him to Prof. Busk, contains Ter. grandis in 

 great abundance, T. vitrea, Rh. psittacea, and other shells. This shell-rock was probably 

 once a portion of one of the old raised sea-beaches attached to the eastern face of the 

 Rock of Gibraltar. T. grandis varies a good deal in shape, for while some specimens 

 are uniformly convex, others are somewhat biplicated. 



In Belgium T. grandis is stated by M. Nyst to occur in the ' Etage Scaldisien' 

 (Sables gris a Bryozoaires) at Antwerp, and, according to the same Palaeontologist, 

 perhaps likewise in the ' Etage Diestien ' Dumont (= Upper Miocene) at Fort De A^ieux 

 Dieux, Antwerp. In M. Dewalque's ' Prodrome de Geologie ' M. Bosquet quotes the shell 

 from the 1 Terrain Tongrien inferieur ' of Limburg ; but M. Bosquet has recently 

 informed me by letter that his identification is more than doubtful, and that there exists 

 no positive evidence of the shell having been found in that formation.

fig. A a— d, 1874. 



This species has been recorded by Mr. A. Bell from the Red Crag of Sutton 

 ('Annals and Mag. of Nat. Hist.,' September, 1870), where it attained large dimen- 

 sions. 



It is mentioned by Mr. S. Wood from the Fluvio-marine Crag of Bramerton, Thorpe, 

 and Postwick ; Chillesford bed, Bramerton ; Upper Glacial, Bridlington ; Post-glacial, 

 March. It has also been met with in the Crag in the neighbourhood of Antwerp, in 

 Belgium, but there, as with us, it is very rare.
