broad flat coraco-clavicular ligament. The medial or sternal end of the 

 clavicle is somewhat expanded and deeply notched for the short stout 

 omosternal cartilage 1 by which it is attached to the front of the 

 manubrium. 



The scapula (PI. XIII, fig. 3) is less angular than iri the majority of 

 marsupials, having a slightly elongate, gently curving outline without 

 sharp prominences. The suprascapular notch, so-called, is not a notch 

 but a long sweeping curve which does not reach its highest point until 

 about two-thirds of the distance from the coracoid process to the 

 vertebral border of the scapula. The axillary border has a slight con- 

 vexity, instead of being practically straight, and it meets the vertebral 

 border in a modified curve which in some specimens may be a trifle 

 angular. The slightly thickened vertebral border is covered by a small, 

 elongated, cartilaginous, or sometimes partly osseous, suprascapular 

 epiphysis. 2 



The spine is relatively low and continuously deflected so that it is 

 nowhere perpendicular to the fossae on either side of it. Thus the 

 antero-ventral triangular half of the infraspinous fossa is overhung by 

 the flat deflected surface of the spine, which continues to the well- 

 developed acromion, turning sharply forward beyond the triangular 

 metacromion. The coracoid process is a prominent prong with a slight 

 notch in its glenoid surface. The superior fossae are nearly equal in 

 extent, the supraspinous usually having slightly the greater surface. 

 The inferior surface or subscapular fossa presents a deep longitudinal 

 channel opposite the base of the spine and on either side of this the 

 surface is somewhat bulging. 



Taken as a whole the scapula of C&nolesies is more similar to that 

 of Sminihopsis than to that of any other form which is available for 

 comparison. It agrees with this in its general outline and in its much 

 deflected spine, whereas practically all other forms have a more angular 

 shape, a less deflected and usually higher spine, and a shorter more 

 abrupt suprascapular notch. 



PELVIC GIRDLE. 



Plate XIII, Fig. 4. 



The pelvis is completely ossified and shows no traces of division in 

 adult specimens. It is relatively long and deep but light in structure. 

 Although it is not especially peculiar in other respects, it is strikingly 

 distinguished from that of all other marsupials by its extremely short 



1 In a skeleton of Philander, this cartilage is partially ossified.

 Thylacinus.
