columns being decisive. A small tooth in the Ipswich Museum 

 Collection is evidently a lower premolar, and I am inclined to regard 

 it as the penultimate one of the present species. With regard to 

 M. Borsoni, I think that the specimens figured by Lankester, op. cit. 

 figs. 3, 4, and provisionally referred to M. turicensis (tapiroides) *, 

 really belong to this species. There is a trilophodont ultimate upper 

 milk-molar in the British Museum (No. 46690) which I also pro- 

 visionally refer to M. Borsoni, while the Museum of Practical 

 Geology in Jermyn Street possesses the last two ridges of a second 

 right upper true molar presenting all the characters of the teeth of 

 this species. 



Sus. — In the Cat. Foss. Mamm. Brit. Mus. pt. ii. p. 268, I have 

 noticed two third lower true molars of a large Stis from the Eed 

 Crag which closely resemble the corresponding teeth of the Pikermi 

 8. erymantliiiis t, but are of rather smaller size. A third left upper 

 true molar in the Ipswich Collection agrees exactly in size with the 

 corresponding tooth of some specimens of that species, and therefore 

 probably indicates the occurrence either of that species or of the 

 closely allied S. nntiquus, Kaup, in the Crag. The smaller Crag 

 species has been provisionally referred to /S'. palceoclioerusX. 



Tapirus. — ThePed-Crag Tapir has been identified with the Eppels- 

 heim T. priscus, Kaup §, but its teeth agree more nearly in size with 

 those of T. arvernensis and the closely allied T. elegans of the Upper 

 Pliocene of the south of Prance ||. 



Hipparion. — The remains of Hipparion from the Crag have been 

 referred to H. gracih ^, although it has been suggested by Deperet** 

 that they may belong to the Pliocene H, crassum, Gervais, which 

 the former writer regards as distinct, although it appears very 

 difficult to distinguish the teeth. 



Rhinoceros. — Most of the molars of Rhinoceros from the Ped Crag 

 in the British Museum which have been referred to R. Schleier- 

 macheri ff present the characters of those of the hornless R. incisivus, 

 and I am therefore disposed to refer them to the latter species $J, 

 although it is highly probable that R. Schleiermacheri, and perhaps 

 R. etruscus, may also occur in the Crag. 



JDiomeclea. — By far the most interesting of the specimens to 

 which I have to call attention are the associated right tarso-meta- 

 tarsus and proximal phalangeal of the outer (4th) digit of a large 

 bird in the Ipswich collection. I have compared these specimens 

 (fig. 2) with the corresponding bones of Diomedea in the Museum 



^ In his description of the Crag specimens, Lankester (pp. 508, 509) has un- 

 fortunately transposed the characteristics of M. Borsoni and M. turicensis. 



t Probably identical with 8. major of the south of France (Lower Pliocene). 

 This name has the priority, but it appears advisable to adopt 8. erymMnthius.
