TERTIAET VERTEBRATA OF THE FAYOM. 
'Die vIna is known only from an imperfect upper half. The olecranon process is 
hiri>je, hut rises very little above the level of the sigmoid notch, which is deep ; the 
shaft narrows considerably beneath the articulation, and its anterior face is crossed 
ol)li(piely by a flat surface which united with the posterior face of the radius. 
JUnd lAruh . — The upper portion of a femur shows that the head is rounded, 
somewhat pedunmdate, and directed upwards. The greater trochanter is comparatively 
small and does not rise to the level of the head. 
No hones of either the fore or the hind foot are known.

Type Specimen . — Portions of a skeleton including upper and lower jaw's with teeth, 
scapula, humerus, and radius (PI. XVII. figs. 4-9); Geological Museum, Cairo. 
This species is the only one at present known. It appears to have been fairly 
common, traces of several skeletons having been observed, but unfortunately in nearly 
all cases the bones are completely broken up and only recognisable with difficulty. 
They occur in the same beds as Moeritherimn lyonsi and Eosiren lihyca, with remains 
of reptiles and fishes. Probably this animal lived in swampy country and perhaps was 
semi-aquatic. In any case the form of the fore limb is such that it was almost 
certainly used for something besides mere progression on firm ground, possibly, as 
already suggested, for digging or scraping away the surface of the soil or for forcing 
the animal through soft swampy ground. 
Form. & Loc. — Qasr-el-Sagha beds (Middle Eocene) : north of Birket-el-Qurun.
