character. The two principal coronal bones, the occipitals, and 

 parietals, are almost entire, and are of the same rectangular form. 

 The parietal foramen is distinctly displayed, and in every respect 

 agrees with that of the other example. The left outer horn is 

 present, and shows no variation in character ; the two inner 

 horns and the right outer horn are broken away. 



The left praemaxillary bone is pressed inwards, and agrees in 

 size and position with that previously described. It has seven 

 teeth, beautifully preserved, the exact number in the other spe- 

 cimen, and, in fact, the praemaxillaries of the two individuals 

 are in every respect similar, only in that now before us the pos- 

 terior pointed extremity is apparently hidden in the matrix. The 

 greater portion of the vomer is preserved, and is studded, in the 

 same manner as in the first specimen, with numerous, short, 

 stout, conical teeth. The left outer or lateral row of vomerine 

 teeth are well exhibited, and are pressed down inwards ; they 

 are ten or twelve in number, and are quite as large as those of 

 the praBmaxillse, and are in like manner striated at the apices. 

 They seem better developed and are rather more numerous than 

 in the other specimen ; but in it these teeth are broken down 

 and are much encumbered with the matrix, and there can be 

 little doubt some of them have entirely disappeared : eight ne- 

 vertheless can be counted. Had we not had the first-described 

 specimen for comparison, we might have taken this lateral row 

 of vomerine teeth to have belonged to either a maxilla or a man- 

 dible pressed inwards ; but after carefully considering the evi- 

 dence for and against, we think it favours the opinion we have 

 adopted, though it is quite possible that we may be mistaken. 

 At the same time it must be remarked that this row of teeth 

 occupies exactly the same position that the lateral vomerine row 

 does in the other specimen, that it is of the same length, and 

 that the number of teeth is apparently the same, two or three 

 having been removed in the first specimen. 



The folded margin of the cranium exhibits in front a longitu- 

 dinal depression, which there can be little doubt indicates the 

 position of the orbit ; indeed, at one point the inner orbital mar- 

 gin can be traced. A similar depression is observable in the
