that from four to six anterior ridges mth the front talon are want- 

 ing. The first three ridges are slightly worn, presenting distinct 

 annular disks, surrounded by a margin of thick enamel. Each of 

 these ridges presents about five digitations converging tipAvards. 

 The specimen, through its deficiency in front, is well adapted for 

 showing one of the most distinctive characters of the species, namely, 

 the low height of the ridges relatively to the breadth of the crown. 

 The fracture in front passes vertically through a ridge, exhibiting 

 the angle of reflexion of the enamel plate. The extreme height of the 

 fourth ridge of the fragment is 4-5 inches, while the extreme width 

 of the crown is 4'1 inches. The height of the ci'own is thus seen to 

 exceed the width by barely half an inch. The proportions in E. 

 (EueJeph.J antiquus and E. \Eiieleph.) primigenius, as will be seen in 

 the sequel, are very different. A longitudinal section of this speci- 

 men has been made, which exhibits very perfectly the relative pro- 

 portions of the ivory, enamel, and cement, together with the cuneiform 

 character of the ivory core of each ridge. It is highly desirable 

 that it should be figured of the natural size, for the guidance of 

 English collectors in discriminating teeth of this species. 

 The principal dimensions are —

This specimen bears such a close resemblance to the corresponding- 

 tooth of the Indian fossil species, E. (Loxod.) phmifrons, that I 

 question if these teeth of the two forms, in the same mineral con- 

 dition, could be distinguished if found mixed in a collection. 



The Irstead collection (Gunn's) contains numerous other molar 

 teeth or fragments of E. meridionaUs, from Bacton, Mundeslej^ 

 Horsea, and Happisburgh, which have not been figured ; and I, 

 therefore, do not think it necessary to describe them on the present 

 occasion : some of them, it is to be hoped, may appear shortly 

 elsewhere. 



The other illustrations of the species, to be noticed in the sequel, 

 are chiefly from specimens in the Norwich Museum, which were 

 liberally transmitted to London for identification by the managers 

 of that excellent institution, and are figured in the ' Eauna Antiqua 

 Sivalensis,' pi. 14 B. The citations which follow, aU refer to that 

 plate, in which the figures are drawn to one -third the natural 

 size. 



Eigs. 1 and 1 a represent the plan and side-view of the penultimate 

 or second upper milk-molar of E. meridionalis. It is a germ-speci- 

 men, without fangs, and a good deal roUed. The crown is composed 

 of six principal ridges, besides front and back talons. It was com- 

 pared with the corresponding tooth of E. (Loxodon) planifrons, 

 which it resembles very closely, but it has a broader crown. 

 The dimensions are —
