There were probably five digits of the fore foot, the inner small or 

 rudimental. The proportions are stouter than in the dogs, but not so 

 much so as in the bears. The phalanges have a length similar to that seen 

 in some bears, but the metatarsals are more elongate. The lengths of 

 the latter are, fifth shortest, then 2d, 3d and 4th. Their condyles are 

 broad, with median keel behind, and shallow supracondylar fossa in 

 front. The first phalanges are about one-third the length of the meta- 

 carpals ; the second of digit No. 2 broad and stout and half as long as 

 the phalange of the first row. An ungueal phalange has a singular 

 form, so that the, claw might be supposed to have a subungulate charac- 

 acter. It is flat, considerably broader than high and with expanded and 

 obtuse extremity. The articular extremity is depressed and transverse 

 concave in vertical, convex in transverse section. The anterior three - 

 fifths of the superior middle line is occupied by a deep gaping fissure, 

 which separates the extremity into two points. The inferior face is 

 entirely flat, there being no tendinous tuberosity. The sides are grooved, 

 and give entrance each to a large arterial foramen proximally. These 

 claws resemble those of Nesonyx, and differ remarkably from those of 

 existing terrestrial Carnivora. 



Of hinder limb the only characteristic pieces remaining are the navicu- 

 lar, cuboid, and an external cuneiform bone. The cuboid is rather 

 stout, with a slight concave facet at one extremity and two at the other, 

 one of them smaller and sublateral. The navicular is wide and flat, and 

 with a strongly concave astragaline facet. Below, it presents two deep 

 oblique concave facets for the cuneiforms, with a small sublateral one 

 on the outer side. The facets of the cuboid and astragalus indicate four 

 well developed digits and another perhaps smaller one. Thus in this 

 genus they were on both limbs probably 5-5, with the inner small. 



The cranium is fractured above* There remain the squamosal and 

 periotic bones, occipital condyles, malar and part of maxillary, both 

 premaxillaries and the greater part of both mandibular rami. The 

 squamosal process of the zygoma is produced inferioiiy far below the 

 auditory meatus, even further than in the bears. Its proximal portion 

 includes, on the lower face, a strong groove at right angles to the axis 

 of the cranium, with its defining margins acute and prominent. This 

 is the transverse glenoid cavity of the carnivorous type. The zygoma 

 has a wide curvature indicating a powerful temporal muscle. The pos- 

 terior angle of the malar extends well posteriorly. Its anterior portion 

 projects, forming a longitudinal rib; there is no produced postorbital 

 prqpes's. The tympanic bone is produced upwards and outwards and 

 forms a tube with everted lips. The opisthotic (mastoid) separates it 

 entirely from the exoccipital, and overlaps the posterior half of the tube 

 by a laminar expansion. A pit in this bone near the meatus externus 

 represents the insertion of the stylohyal ligament. There is no bulla, 

 the tympanic chamber being small and with thick walls. The character
