Ipswich Museum are nearly as large as those of full-grown speci 

 mens of PJiyseter macrocephalus. 



Hob. Europe (Belgium and England). 



The majority of the following teeth apparently belong to this form. 



46688. The greater part of a tooth, with a considerable portion of 

 the coating of cement broken away ; from the Red Crag 

 of "Woodbridge, Suffolk. This and the following specimen 

 agree precisely with the type-teeth figured by Gervais and 

 Yan Beneden in the ' Osteographie des Cetaces,' pi. xx. 

 figs. 29-32. Purchased, 1875. 



39009. The greater part of a tooth, wanting considerable portions 

 of the cement-layer ; from the Red Crag of Suffolk. 



Purchased, 1865. 



36655. The basal portion of a tooth which has been transversely 

 bisected. The cement is of great thickness, and the 

 dentine core (dark brown) comparatively small ; the in- 

 ferior aperture of the pulp-cavity is very small. 



Brown Collection. Presented by Prof. Sir R. Owen,

 side ; from the Red Crag of Suffolk. Purchased, 1867.

 stowe. Purchased, 1874. 



47404. Two transverse sections of a tooth ; from Felixstowe. In 

 the larger specimen the osteodentine occupies a consider 

 able space, and shows the characteristic nodular structure. 



Purchased, 1876. 



27854. The slightly imperfect left periotic, provisionally referred 

 (Fig.) to this species 1 ; from Felixstowe. This specimen (fig. 11) 



1 This specimen can only have belonged either to the present form or to 

 Scaldicetus or Balanodmi ; its large size and the circumstance that teeth of 

 Eucetus appear of much more common occurrence than those of the two latter 

 is in favour of the former reference.
