This is probably a young specimen of Ghhiocephalus Svhuval. 

 The skull differs in being rather slenderer in front, and in the inter- 

 maxillary not being rugose in front. In the Catalogue of the Mus. 

 CoU. Surg. 165. n. 1138, it is called " the skull of a small Grampus," 

 Hunterian, and n. 1136, " the skull of a large Grampus," Hunterian. 

 It appears to be the skull which Prof. Owen gives the measurements 

 of, under the name of D. melas, in his account of Phoccena crassidetis, 

 in the work on British Fossil Mammalia. 



The skuU of the Black Grampus (Delphinus melas), which formed 

 part of the Hunterian Collection in the Museum of the College of 

 Surgeons (see Cat. p. 456, n. 2518), is thus described — 



"Number of alveoli i|^= 46. The teeth are moderately small, 

 conical, subincurved, decreasing to the two extremes of the series. 

 The fourth to the tenth inclusive are subequal. The symphysis of the 

 lower jaw is subtriangular, and curves from below upwards at its 

 extremity."
