JiATUACIIIA SAUKNTIA. 95 



the inferior part of the tympanic and with the malar ; this process 

 approaches the joint, witliout ])eing in connexion mth it ; the os 

 jotery'8'oul(nim appears to be entirely separated from the tjTnpanic if 

 looked at from above, but both are united beneath without any 

 \asiblc suture. Thus also the malar is partly united with the t\-m- 

 pamc bone. The parietals are relatively very narrow, not quite half 

 us broad as the frontals, leaving a great space for the united temporal 

 and orbital grooves ; they have an irregularlv serrated and truncated 

 tront edge, and a pair of spinous prominences l)ehind for tlie insertion 

 of muscles of the neck. The frontals are the largest bones of the 

 whole skuU, subtriangidar, with a flat smooth surface ; the two upper 

 ridges of the occipital bones are veiy prominent, obhquely situated • 

 petrosal conspicuoasly separated by sutures. The palatine bones are 

 elongate, as generally, but without a shaq) ridge. The diaiioiihyses 

 ot the seven midtUe vertebiw do not differ very much from one 

 another, either m length or in direction ; those of the third and 

 eighth are nearly horizontal ; those of the ninth vertebra are veiy 

 thicjk, trihedral, with rounded ridges ; the coccygeal style is pro\-ided 

 with a rather lugh ridge, and equal in length to the vertebral column, 

 termed by the eight posterior vertebrae. The claA-icula styliform 

 much weaker than the ossa coracoidea, which, much dilated at the 

 inner end, form a long suture and give much firmness to the thorax • 

 the processus xiphoideiis, much dilated in front, less behind, is formed 

 by a single bone, and has a broad half-ossified cartilage beliind ■ the 

 mamibnumsterni styHform, and bifid beliind for the articulation "^^-ith 

 the clavicles ; sui)ra-scapula broad, half-ossified ; humerus not much 

 longer than fore-arm, with a moderate ridge near its head ; the Hiac 

 bones are rather broad, channel-shaped, mth the concaWty bent in- 

 wards, both nearly paraUel to one another ; femur cyHncbical with- 

 out ndge, rather shorter than the cms ; the first cuneifonn bone 

 very small. 



The I ntesHnes exhibit no pecuUarity, except the hver, both halves 

 of wlucli are neariy entirely separated from one another : an ex- 

 ceedingly narrow band of the parenchyma passes behind the heart 

 uniting both halves. The gaU-bladder is smaU, not immediately 

 attached to the parenchyma, but suspended by a fold of the perito- 



neum
