ON SOxAIE NEW AND LITTLE KNOWN CREODONTS. 
Vvrfihne Iroin nearly all the regions arc represented in the specimen. The atlas 
is viverrine in character ; the transverse processes are moderately exjjanded, rather 
more so than in the MusteUda>. and less than in the Ganidce, and perforated for the ver- 
tebral artery ; the anterior condyles are quite deep, the neural arch broad and stout and 
the inferior arch slender. The axis has a short conical odontoid process ; the centrum 
is broad, depressed and strongly keeled ; the atlanteal faces are transversely directed and 
not emarginated by the neural canal, as in Mesonyx ; the post-zygapophyses are placed 
low on the arch. The spine is missing from the specimen. The dor. sal vertebrae have very 
small centra, which are subtriangular in section and have nearly flat faces. No pro- 
cesses arc preserved on any of them. The lumbars are of particular interest as show- 
ing the typical creodont structure of concave prezygapophyses interlocking strongly 
with the sub-cylindrical postzygapophyses. The metapophyses are inconspicuous 
and the ana{)ophy.ses small. No vertebrae from the sacral or caudal region are 
preserved in the specimen. 
.\ fairly complete account of the fore-limb may be given, as portions of the scapula, 
liumerus, ulna, radius and manus are represented. Of the scapula only the distal end 
is preser\ecl, enough, however, to show a broad shallow glenoid cavity and stout 
eonicoid h(K)k ; the spine commences very far back from the glenoid cavity and prob- 
ably tlie acromion, if present at all, did not project over the cavity. The liumerm is 
(put(> viverrine in character, and in a less degree like that of some of the Mustelidce, 
but stouter; the head is flattened, the tuberosities low and the bicipital groove wide; 
the shaft is strongly curved and the very prominent deltoid ridge runs far down; an 
epitrwhlear foramen is present. The ulna is peculiar for the great length of the olecran- 
on. much exemliug that found in the recent carnivores. This would seem to be a 
chanicter very prevalent among the creodonts, as well as certain insectivores, e. g., Cen~ 
Mrs. The sigmoid notch is deep, but the humeral facet is small— most of the humeral 
tr(K-hlea lH‘ing occupied by the radius; the shaft is very broad, rounded on the internal 
surface and channelled on the e.xtemal ; the distal end is expanded, but unfortunately 
the articular face is broken off. Of the radius only the proximinal end is preserved. 
I he head is transversely extended and occupies most of the trochlea of the humerus, 
t)ms allowing no movement of supination. The carpus is creodont in character. The 
s<-aphoid is ver)- low and flat ; its proximinal surface is rounded and shows a small inner 
tul)erosity ; distallly there* are three articidar faces ; the shape of the bone is very much 
as lu Mrsouyx. The lunar is very small, it is not co-ossifled with the scaphoid, which 
It but slightly exceeds in vertical diameter ; distally it shows a small facet for the mag- 
num and a larger one for the unciform. The pisiform is short and stout. The only 
other carpal bone present in the specimen is the unciform which is verv peculiar. 
1C proximal surface shows a strongly convex facet for the lunar, and the radial side 
of the cuneiform facet is also strongly convex, while its ulnar side is concave ; the distal 
surface is concave from side to side so that the outer edge of the bone is very thin. In
