a. Cast of skuU from Mr. Sowerby's specimen in the Anatomical 

 Museum, Oxford. Presented by Dr. Acland. 



Besides the beautiful figure of the male which was thrown ashore 

 on Elginshire in 1800, engraved in Sowerby's ' British Miscellany,' 

 there is a drawing of the head as sent by Mr. Brodie, made by 

 Mr. Sowerby, exhibited by him at one of Sir Joseph Baiiks's Sun- 

 day-evening parties, and now preserved in the Banksian collection 

 in the British Musum. The skuU was preserved in Mr. Sowerby's 

 museum in Mead's Place, Lambeth, and when distributed at his death 

 it was purchased by the Eev. Dr. Buckland, the Dean of "West- 

 minster, and sent to the Anatomical Museum in Oxford, whence 

 Dr. Acland kindly sent it to me for examination. 



While in Mr. Sowerby's possession, M. de BlaLnville, when on a 

 visit to England, made a slight sketch of the skull (engraved in 

 ' Zool. Erebus and Terror,' t. 5), and, under the name of D. Sower- 

 biensis, gives the following description of it : — " Tete osseusse, la 

 machoire superieure est plus courte et infiniment plus etroite que 

 I'inferieure qui la regoit; en outre cette machoire inferieure est 

 armde de chaque cote et au milieu de son bord d'un seul dent tr^s 

 fort comprimie et dirigee obliquement en arri^re. L'orifice de 

 I'event est en croissant dont les comes sent tournees en avant." — 

 Blainv. Desm. Diet. H. N. ix. 177. 



The above description and BlainviUe's sketch show that it belonged 

 to the genus ZipMus of Cuvier, before only known in the fossil state ; 

 and the examination of the skull has proved the accuracy of these 

 determinations. 



Before discovering the drawing of the skull, I was induced, from 

 the lateral position of the teeth and small size of the fins, to consider 

 this species the same as the Debphinorhynchus micropterus of the 

 £oast of France and Belgium (see Ann. & Mag. N. H. 1846), believing 

 the diiference in the size of the teeth (which Mr. James Sowerby's 

 description appears to indicate) to be only a peculiarity produced 

 probably by the age of the specimen ; and further study has induced 

 me to return to that opinion.
