1 52 Bemains of M&stodon giganteus and M. latidens 



which I remember having had offered me by some fishermen 

 at Bacton, on our coast, in 1824 ; and, but for their cupidity, 

 I should have possessed it. This singular specimen, from the 

 decomposition of the crusta pelrosa of the posterior end, ex- 

 hibits the upper part of two plates, terminating in points, 

 which may be closely represented by placing the palms of the 

 hands together, dropping one hand a little, and keeping the 

 ends of the fingers a trifle apart. Specimens approximating 

 this are not uncommon. Parkinson mentions one, in his 

 possession, resembling the paw of a bear. I have one in 

 which the protrusion of the points gives it a similar appear- 

 ance ; but, among 



all the specimens "MM ^%^ 22 

 of the grinders of 

 the elephant from 

 our coast, I have 

 not seen any thing 

 like the mammil- 

 lated processes of the tooth of the mastodon [mastos, a teat ; 

 odous, odontos, a tooth; Jigs. 22, and 23.] associated with the 

 plates of that of the elephant : another criterion is, that these 

 points are in rows, whilst the mammae of the teeth of the 

 mastodon (with the exception, I believe, of M. elephantoides) 

 are irregular. 



These remains appear to be of two species, Mastodon gi- 

 ganteus and latidens. 



M. giganteus (Parkinson's Organic Remains, vol. hi. tab. i.). 

 The large grinder figured by Smith, in his Strata Identified, 

 was reported to have been found at Whitlingham, near Nor- 

 wich ; and, when at Scarborough, last summer, I put the 

 question to him, and he assured me that it was so found. I 

 believe that the fragment of a grinder which I found, some 

 years since, at Bramerton, also belongs to the same species ; 

 as does that of the Rev. William Foulger, found at the same 

 place. When I found my fragment, I think the whole tooth 

 must have been there ; as it was with a large mass of brown 

 decomposing matter, the firmer parts of which I placed in 

 my basket for further examination. 



M. latidens (Geological Trans., second series, vol. ii. tab. 

 36. to 39.). The figures No. 22. a. and b. are of the fragment of 

 a grinder : the figures are of one fourth of the diameter of 

 the original, and represent a front view and a side one : found 

 at Horstead, in this county (Norfolk), about six miles north- 

 east of Norwich ; which, on comparison with those of that 

 species from Ava, in the collection of the Geological Society, 

 will be found to agree pretty well. This interesting specimen
