segment resembles the stalk of the presternum, but the other four presternal 

 segments increase in breadth as they are traced backwards. The first three show 

 traces of a keel. The xiphisternum is a short cylinder, capped with cartilage. 



The scapula is very narrow, almost rod-like ; the post-scapula being reduced to a 

 very narrow fossa, and the prescapula to an extremely narrow, slightly externally 

 reverted ridge. The spine is deep and strong, and marked at its middle by a feebly 

 tuberous eminence from which the spine shelves off above to the thick and rounded, 

 but very narrow, supra-scapular border. The acromion and metacromial processes 

 resemble Crocidura. The former is applied to the outer side of the head of the 

 humerus immediately below the anterior surface, to which it is attached by liga- 

 m.ent, and forms with the thin supra- glenoid rod of the scapula a complete and 

 rather high arch, the external end of the clavicle being placed over it. The 

 coracoid is represented by the anterior projection of the glenoid surface of the 

 scapula. The external half of the clavicle has a slightly downward curve. Its 

 outer end is curved backwards to be applied to the upper surface of the acromion, 

 and it terminates in a small meso-scapular ossicle, its inner end having the rudi- 

 ment of a precoracoid. The humerus is about one-fifth shorter than the ulna, and 

 it has the form of the humerus of Crocidura. The antero-posterior, flattened and 

 laterally extended upper half of the bone is cm-ved backwards, and the deltoid 

 ridge is very prominent and begins at the middle of the anterior margin of 

 the articular surface of the head, half-way between each tuberosity. The supra- 

 condyloid foramen is well developed, but there is no supra-trochlear foramen, but 

 the anconeal fossa is deep, and both condyles are prominent. The olecranon is 

 well developed and rather flattened on its outer surface. The radius and ulna are 

 distinct. 



The carpus has a radicUe, intermediimi, ulnare, and pisiform, a united fourth 

 and fifth carpcde, but no centrale, as in Crocidura. 



The pelvis is very narrow and is considerably curved backwards, downwards, 

 and forwards, and is much contracted, the symphysis being separated from the 

 sacrum by so restricted an interspace, and being so filled up by the sacral hypapo- 

 physes, as in Talpa, that there is no room for the pelvic viscera to pass internally, so 

 that they are continued out below the pelvic symphysis as in that genus. The 

 ilium is rod-like and paraUel to the vertebral column, its anterior half being only 

 slightly divergent. The acetabulum, placed about the middle of the pelvis, is 

 immediately opposite and close to the pelvic symphysis, which is very short, but 

 the bones are closely in contact with each other. Behind the symphysis, the pubes 

 and ischia are externally divergent, but less so than in Talpa, and they enclose a 

 long, rather narrow, thyroid foramen, the lower or pelvic wall of which is rod-like, 

 the upper or ischial wall being prolonged downwards and forwards, the pubes form- 

 ing a well marked, flattened spine which projects in that direction, the tuberosity 

 of the ischium being rounded off and scarcely determinable. The bodies of the 

 sacral vertebrse almost fill up the space that intervenes between the thyroid 

 foramina. The dorsal surface of the ischium of either side is amalgamated with
