has shown that the name Chcsromenjx silistrensis should be applied to 

 the specimen from the Garo Hills figured hy Falconer and Cautlej'-, 

 under the name of Anthracotherium siiistrense, in the " Fauna Antiqua 

 Sivalensis" (pi. Ixviii. figs. 22,22«). At the time of writing that notice 

 no trace of the specimen, which consists of a fragment of the right 

 maxilla/ could be found; and judging from the figure, and a cast 

 (which now appears very inexact), he was under the impression that 

 it contained three teeth which were considered as the true molars. 

 The original specimen has recently been found in the British 

 Museum (No. 19040) ; and it really contains only two teeth, which 

 are respectively the third and fourth milk-molars. A comparison of 

 the fourth milk-molar of this specimen with an upper true molar 

 from Sind which is figured in the " Palaeontologia Indica " (op. cit. 

 pi. xxiii. fig. 11), under the name of Sivameryx sindiensis, shows that 

 the two are certainly generically, and very probably specifically the 

 same; the slight differences between the two being not improbably 

 merely due to difference of serial position. The figure in the F. A. S. 

 does not exhibit very clearly some of the characteristic features of 

 the Garo Hills specimen ; and from this, coupled with the reference 

 of the teeth of this specimen to the permanent instead of the milk- 

 series, the two specimens were referred to distinct genera. 



It follows from the above that the genus Sivameryx must be 

 abolished. Charomeryx has been previously placed in the neighbour- 

 hood of Merycopotcnnns, but a recent comparison with specimens in 

 the British Museum renders it probable that its affinities are rather 

 with Dichodon. 



The occurrence of Ghcsromeryx and Anthracotherium siiistrense in 

 Sind and the Garo Hills renders it probable that at least a part of 

 the Siwaliks of the latter district correspond to the lower division 

 of that series. 



IV. — Note on the Posidonomta Becheri Beds of Budle 

 (Northumberland), with Kemarks on the Distribution op 

 THE Species.

BUDLE BAY, on the coast of Northumberland, between Holy 

 Island and Bamburgh, is the estuary of the little river Waren. 

 The rocks of the country belong to the Bernician Series or, in other 

 words, to the alternating grits, limestones, shales, and coals which 

 in northernmost England represent the Carboniferous Limestone 

 Series. The northern shore of the Bay is a broad expanse of sand 

 stretching as far as Fenham Flats and Holy Island, but the southern 

 is rocky though not lofty. The Great Whin Sill (the well-known 

 intrusive sheet of Basalt^) is present here, and the late Mr. G. Tate 

 of Alnwick has more than once described it as it occurs here, asso- 

 ciated with the beds which form the subject of this note. In 1872 



1 The figure in the F. A. S. is reversed.
