In the Zoology of the Erebus and Terror, tab. 10, is a copy 

 of a most accurate drawing, by Mr. R. Templeton, of a specimen 

 caught on the south of Ireland, in November 1828. The follow- 

 ing are its measurements :

There is some difficulty about the colour of this species, which 

 may arise from two being confounded under one name. Bonna- 

 terre, Montague and Wright describe it as black above and 

 whitish beneath; O. Fabricius as all blackish, the belly a little 

 whiter and the young paler; Schlegel figures it of a uniform 

 deep black colour. 



The following are the measurements of five skulls, the first 

 being Montague's specimen in the British Museum, and four in 

 the College of Surgeons; the fourth is No. 1126, and the fifth 

 No. 1125 of the College Catalogue:

In the skull of Montague's specimen, in the British Museum, 

 the 4th and 10th teeth from the front on each side appear by the 

 hole to have been larger than the rest. We have a second im- 

 perfect skull of the same measurement. 



The skull of the skeleton presented by Mr. Howship, in Mus. 

 Coll. Surg. (n. 1 125), taken below the Nore, in June 1828, has the 

 teeth f f ,the two hinder upper without any opposite them; the 4th, 

 5th and 6th upper are largest, the middle lower are truncated ;
