Sum/nary. — Awaiting the discovery of a more complete skeleton of 

 this genus, we have provisionally referred it to the foniily Morosaitridce 

 because of the stout nature of the pubis ; the similarity of the proxi- 

 mal portion of the scapula to the scapula of Morosai/n/s, and the 

 comparatively solid condition of the sacral centra. 



There is little to be said of the size of this animal, for, as has been 

 already suggested, like most reptiles the Sauropoda probably continued 

 to grow throughout their entire life. Though all parts of the osseous 

 structure of this individual, which are preserved, are of comparatively 

 dense bone, the immature age of the specimen cannot be questioned. 

 The distinct neural sutures in the cervical and dorsal region, the sep- 

 arated sacrals, and the absence of the coracoid all indicate a com- 

 paratively young animal. By comparison of the fore and hind limbs 

 (Plate XXV, Figs, i and 2) it will be observed that the fore limb is 

 about two-thirds the length of the posterior, indicating a type whose 

 movement on land was undoubtedly quadrujjedal.
