44058. Cast of the imperfect cranium. The original, which is the 

 type, was obtained from the London Clay near Heme 

 Bay, Kent, and is described and figured by Owen in the 

 Trans. Geol. Soc. op. cit., and also in the ' British Fossil 

 Mammals and Birds,' pp. 419, 422 ; it is preserved in the 

 Museum of the Royal College of Surgeons (No. 1954). 



Presented by the Royal College of Surgeons, 1873. 



38801. The imperfect cranium, showing the last five cheek-teeth ; 

 (Fig.) from debris of the London Clay in the Red Crag of 



Suffolk. Figured by Owen in the Geol. Mag. dec. 1, 



vol. ii. pi. x. fig. 2 (1865). 



Presented by Rev. Prof. Henslow, 1861. 



44115. Fragment of the left maxilla with the last five cheek-teeth, 

 (Fig.) another of the left ramus of the mandible with the cor- 

 responding teeth, and the cast of the complete cranium 

 and mandible; from a septarian nodule in the London 

 Clay near Harwich, Essex. These specimens are figured 

 by Owen, under the name of Pliolophus vulpiceps (of 

 which they are the type), in the Quart. Journ. Geol. Soc. 

 vol. xiv. pis. ii., iii. The skull appears to have been 

 originally extracted entire from the matrix, and the cast 

 made, after which it was cut up, and the two fragments 

 are now alone forthcoming l .
