Flower, W. H. Description of the Skull of a Species of Xijohodon, 

 Cilvier. Froc. Zool. JSoc. part 1, pp. 3-7, pi. i. 



Obtained from a rolled and waterworn nodule, from near Woodbridge, 

 Suffolk, and apparently of " Diestian " age, as the matrix resembles 

 the '' Box Stones " of the Crag. This skull, which has the teeth in a 

 continuous series, is most nearly allied to Cuvier's Xiplwdon ; it is pro- 

 posed to distinguish it as X. 'platyceps. E. T. N.

 Abstract of the lectures. Special attention is given to the gaps 

 between orders or other large groups, and to the way in which some of 

 these gaps are filled by extinct species. L. C. M.
