the Common and Grey Seals, the Common, Sibbald’s, and Lesser 
Eorquals, the Sperm, Beaked, and Pilot Whales, the Grampus, 
Bottle-nose and White-beaked Dolphins, and the 1^’arwhal, which 
Mr. Eoebuck records as “ very doubtful.” The Broad-fronted 
Beaked Whale {H. latifrons), which is included in Mr. Eoebuck’s 
list, I omit, as it has proved to be the adult male of H. rostratum. 
Yorkshire, according to the standard I have adopted, thus possesses 
forty-three species, and two others, which must be considered 
doubtful (marked 1), out of a total of sixty-nine. 
For the list of the mammals of E’orthumbkrland and Durham 
I am indebted to the Catalogue by Messrs. Mennell and Perkins, 
published by the Tyneside Naturalists’ Field Club in 1863. 
These gentlemen enumerate fifty-nine species, commencing with 
Homo sapiens, and including all the domestic animals; but on 
submitting the list to the same rules by which we have been guided 
in determining which species should be retained or which rejected 
in the preceding counties, precisely the same number remain with 
which Yorkshire has been credited. Of these, thirty species come 
under class E; under class A, I include eleven species, some of 
which, perhaps, should be more properly placed in the preceding 
section, as Daubenton’s Bat, Eeddish-grey Bat, and Whiskered 
Bat, about each of which one would be glad of more recent 
information; four others, marked with a 1, viz., the Serotiue (which 
may possibly have been a Noctule), the Wild Cat, Atlantic 
Eight-whale, and Eed Deer, I think must be considered 
doubtful. 
In addition to these may be mentioned the Hooded Seal, 
taken in the Orwell (claimed for both Essex and Suffolk), now 
in the Ipswich Museum, also an undoubted specimen of the 
Narwhal, wliich was taken in the year 1800, near Boston, in 
Lincolnshire. We may therefore claim for the Eastern Coast of 
England, certainly, fifty-three, perhaps, also, the Scrotine, Wild 
Cat, and Eed Deer, or fifty-six species, out of the total number 
of sixty-nine. 
I have little doubt that one or two additional species of Bat 
might be added to the Norfolk list if that group were more care- 
fully studied. I also think it highly probable that the Bottle-nose 
Dolphin (D. iursio) is not unfrequent off our coast at certain 
seasons of the year; and I am surprised at the absence of the
