1876, will be found described and figured, as before stated, in the 
‘ Proceedings of the Zoological Society ’ for 1876 ; the fourth I have 
now the pleasure of recording. The skull of Mr. Prightwell’s 
specimen is in the Norwich Museum, and not in the British 
Museum, as repeatedly stated by Dr. Gray, and as frequently 
quoted on his authority. The error arose, as Dr. Gray explained 
to me, from his being under the impression, that the skull Avhich 
was sent to him for inspection was intended for the national 
collection, whereas he was subsequently requested to return it to 
Norwich. A good figure of the adult animal is still a desideratum, 
that by Miss Brightwell being obviously incorrect. 
Appended are some of the principal measurements of this 
specimen : —

Note. — On the 22nd of March, 1880, another young female of this 
species was landed from one of the Yarmouth boats which liad 
been ITcrring-fisbing somewhere in the English Channel. I could 
not, however, ascertain precisely where it was taken. In colour it 
very closely resembled the Yarmoutli specimen just described, but 
was rather larger in all its proportions. I have appended the
