the pterygoids and their relations to the vomer, the palatines, 

 and to the sphenoid. Tiie second fracture shows the ai-ti'ju'a'ion 

 of the large median plate of the prcmaxillary with the vomer ; 

 and that of the vomer with the si)h('noid. The right »'i)ii)terygf»id

No, ?). A crushed skull with low^er jaw. The skull above is 

 much weathered, and much of the matrix remains. Inferiorly 

 the specimen has been transversely fraciui-ed and the whole of the 

 palate has bten most bc-autifully dis;)Iayed. In the sphenoid a 

 very short distance behind the suture with the jitcrygoids are a 

 pair of email round foramina, which may be the foramina for the 

 internal carotids. The relations of the squamosal, exoccipital ami 

 articular to the quadrate are well shown, and the little bone which 

 I regard as probably the tympanic, is very distinctly seen. Above 

 it and h ing in the large oval foramen which it forms, are seen 

 tw^i ossic'es, one behind the supposed tympanic and one in front. 

 As the S} ecimen is somewhat crushed and the ossicles probal)ly 

 displaced, it will pei-haps be better not to give a detailed descrii.- 

 tion of the appearances. The lower jaw is well displayed.

 Till' lower jaw^ is almost entirety gone, and the sui-faces of the 

 cranial ))oi.es considerably weathered. The front of the palate is 

 fairly well shown, and the greater part of the occiput. Both the 

 median preparietal and interparietals are w'ell seen.

No. 5. An imperfect skull of a small animal. The snout is 

 fairly well shown, but the frontal region is covered with matrix.
