It seems possible that these bones must be referred to JE. mul- 

 leri, a species recently named by Milne-Edwards and Grandidier (4), 

 but till a description and further measurements of the limb- 

 bones are published it is impossible to be certain. The tibio-tarsus 

 is, however, slightly smaller, and the tarso-metatarsus slightly 

 larger, than those of which the above-mentioned authors give the 

 dimensions. 



At first it appeared possible that these bones might be referred 

 to JE. medius, Milne-Edw. & Grand., since the femur on which 

 that species is founded is, like the bones in question, intermediate 

 in size between the femur ascribed to JE. maximus and that of 

 JE. hildebrandti. Closer examination, however, renders it evident 

 that the femur referred by Milne-Edwards and Grandidier to 

 JE. maximus is too large in proportion to the metatarsus on which 

 that species must be regarded as based, and that it probably belongs 

 to the larger form described below under the name JE. titan. On 

 the other hand, the type of JE. medius agrees fairly well in relative 

 size with the other limb -bones of JE. maximus and may belong 

 to that species. If this is the case, then the name JE. medius 

 becomes a synonym, and, as was remarked above, the remains here 

 described must be referred to another species, possibly JE. mulleri. 



The phalangeal bone appears to be the first of the inner toe of 

 the left foot. It measures 5*1 cm. long; 2*7 cm. from side to 

 side and 2*4 cm. from above downwards at the proximal end ; 

 2*4 cm. from side to side and 1*7 cm. from above downwards at 

 the distal end. The proximal articular surface is slightly concave ; 

 its upper and outer borders are convex, the inner flat and the 

 lower concave. It is more compressed from above downwards 

 than the corresponding bone of Dinomis ; and its distal articular 

 surface, the groove of which does not extend on to the dorsal 

 surface, is rather wider in proportion to the length. The shortest 

 vertical diameter is 1*1 cm. 



Remains of iEpyornis from the South-west Coast. 



The chief localities in which these were collected are Itampulu- 

 Ve, near Murderers' Bay, and Amboulisatra. 



All the bones present a very fresh appearance, and some have 

 evidently been rolled on the beach. At least three species are 

 represented, ranging in size from a form much larger than 

 JE. maximus to one which is probably identical with the JE. modestus 

 or the Mulleromis agilis of Milne-Edwards and Grandidier (4). 

 The specimens include more or less perfect femora, tibio-tarsi, 

 tarso-metatarsi, a fibula, several vertebra?, and a fragment of a 

 pelvis. 



In the collection from Itampulu-Ve occur some tibio-tarsi and 

 femora of gigantic proportions ; some of these have aheady been 

 briefly noticed in the ' Geological Magazine,' January 1894, where 

 they are referred to a new species, JEjoyornis titan. 



There are two specimens of the tibio-tarsus, right and left
