E. (LOXODON) MERIDIONALIS. 133 



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 crown is thus seen to exceed 

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

 (Eueleph.) antiguus and E. (Eueleph.) primigenius, as will be 

 seen in the sequel, are very different. A longitudinal section 

 of this specimen has been made, which exhibits very perfectly 

 the relative proportions 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 : — 



Length of the fragment, 7'5 in. Width of crown at the section, 3-8 in. Height 

 of front plate of enamel, 3"9 in. Width of crown at third ridge, 4 - l in. Height 

 of enamel-plate of fourth ridge, 4 - 5 in. 



This specimen bears such a close resemblance to the cor- 

 responding tooth of the Indian fossil species, E. (Loxod.) 

 planifrons, that I question if these teeth of the two forms, in 

 the same mineral condition, could be distinguished if found 

 mixed in a collection. 



The Irstead collection (Gunn's) contains numerous other 

 molar teeth or fragments of E. meridionalis, from Bacton, 

 Mundesley, 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 Uberally transmitted to London for identification 

 by the managers of that excellent institution, and are figured 

 in the ' Fauna Antiqua Sivalensis,' PI. XIV. B. The citations 

 which follow all refer to that plate, in which the figures are 

 drawn to one-third of the natural size. 



Pigs. 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-specimen, without fangs, and a good deal rolled. 

 The crown is composed of six principal ridges, besides front 

 and back talons. It was compared with the corresj^onding 

 tooth of E. (Loxodon) planifrons, which it resembles very 

 closely, but it has a broader crown. 



The dimensions are : — 



Length, 2-6 in. Width of crown at first plate, 1*15 in. Width of crown behind, 

 I '4 in. Height of crown at fifth ridge, T55 in.
