Dr. Jacob, in his description of Cetodiodon Hunteri (Dublin 

 Phil. Journ. 1825), observes, that there are no teeth in the palate. 

 He believes that the three skulls in Dublin, viz. of the skeleton 

 in Mus. Coll. Surg. Dublin ; a skull, Royal Dublin Society ; and a 

 skull in the Museum of the School of Anatomy, Peter's Street, 

 Dublin, belong to one species ; they all have two teeth in the 

 lower jaw, hid in the gums. In the Zoology of the Erebus fy 

 Terror, t. 3. fig. 4 & 5, is a representation of one of the skulls of 

 this species in the Dublin Museum, from a drawing kindly com- 

 municated by R. Ball, Esq. 



There is a skeleton of this species in the Museum of the Edin- 

 burgh University. 



By the kindness of Mr. S. Stutchbury I have been enabled (in 

 the Zoology of the Erebus and Terror , t. 3. f. 1, animal, f. 2, tail, 

 f. 3, blowers) to give a new figure of this species, from a drawing 

 made by Mr. W. H. Baily, of a specimen taken at Aust Passage, 

 Oct. 1840. The measurements, on the drawing taken at the time, 

 are as follows : 



ft. in. 



Length, entire, along the back 22 2

Girth on widest part 12 6
