more closely with Schlesinger's figure of a specimen *, a rather 

 older animal, which is named var. stcbtapiroidea, but which is 

 noted as not typical, 



Tlie third lower molar of this present specimen agrees, however, 

 neither with those figured by Schlesinger for var. typiccff, nor 

 for var. subtapiroideaf, nor with any of the corresponding teeth 

 of angustidevs in the British Museum collection or at Cambridge. 



On the other hand, there are four specimens of third lower 

 xnolars in the present collection whicli agree in a certain point 

 among themselves and also with that described by Lydekker a,s 

 the type tooth of var. palmndica. 



There are the usual four ridges and small talonid. Each ridge 

 is formed of two cusps, each cusp being unequally divided into a 

 large outer and small inner one, the two smaller cusps lying towards 

 the middle line of the tooth, and thefour cusps which constitute the 

 ridge are arranged in a straight line at right angles to the long 

 axis of the tooth. The only exception to the division of the cusps 

 is that the inner cusp of the fourth ridge is practically undivided. 

 So far these characters approximate to those of suhtapiroidea ; 

 the first and second valleys, however, have each a large cusp 

 standing up separately in unwoi'n specimens from the ridges, but 

 showing in worn specimens as being more connected to the 

 anterior ridge than the posterior ; the third valley in this speci- 

 men has no cusp Ausible. This arrangement does not appear to 

 be that of Schlesinger's var. tapiroidea. A reference to his 

 figures shows that it should have the valley cusps small or 

 absent % and the main cusps clearly divided, while in var. typica 

 the main cusps are less clearly divided and the valley cusps are 

 prominent. There are, moreover, two cusps to each valley, the 

 anterior being derived from the posterior fiank of the external 

 cusp of the anterior ridge, and the posterior from the anterior 

 flank of the corresponding cusp of the posterior ridge §. 



A specimen of a small form of typica from Sansan, in the 

 Cambridge Museum, is figured for comparison with the Indian 

 forms (PI. III. fig. 1). 



Either of these forms c&,n be matched by specimens from the 

 Middle Miocene of France in the British Museum collection. 

 The valley cusps may be large or small, but always show the same 

 tendency to be two in each valley. The Indian specimens all 

 show single cusps in the valleys, large in the first, smaller in the 

 second, and in the third valley may even be absent. 



Lydekker |i states that var. p>alcGindica is separated on account 

 of a " somewhat greater development of the accessory columns."

§ This arrangement can clearly be seen in his fig. 4 of plate viii., where a string, 

 used to support the specimen, runs between the two cusijs in the second valle}' of the 

 tooth.
