14. Grampus Cuvieri ; Delphinus griseus, Cuvier. 
The Rey. Charles Bury sent me the head of this species, which 
was taken on the coast of the Isle of Wight in 1845. The ani- 
mal is black above and whitish beneath, not gray as Cuvier’s 
name would indicate ; the figure first sent him from which he 
described it was of that colour, and he mistook it for the real 
one.

16. Beluga Catodon; Physeter Catodon, Linn. 8. N. from Sib- 
bald; Balena albicans, Miller; D. leucas, Pallas. 
We have a fine large specimen of this species in the British 
Museum. 
17. Monodon Monoceros, Linn. 
I may add that the characters of the genera and species are 
given in the monograph of Cetacea in the Zoology of the Erebus 
and Terror. 
The Finner, Balenoptera Physalus, appears to elongate the part 
of the body between the fins as it arrives at maturity ; in the small 
ones (females ?), from fourteen to twenty feet long, the pectoral 
fins are about one-third, and the dorsal two-thirds of the length 
from the end of the nose ; but in the larger specimens, male and 
female, the middle of the body appears to lengthen twice as fast 
as the other parts, for in these the pectoral is about one-quarter, 
and the dorsal three-quarters the entire length from the end of 
the nose. 7

No. VII. Notice of some Birds from Western Africa. 
By the attention of a friend in Liverpool we have received a small 
~ collection of birds procured by the vessels trading to the Bonny 
and Old Calabar rivers, and as the species from these regions are 
comparatively inaccessible to the naturalist, except under great 
danger and privation, we have thought that a list, with remarks, 
might not be unacceptable to the ornithological readers of the 
‘Annals.’ One species we have been unable to reconcile with 
any that has hitherto come under our notice, and have given it as 
undescribed. 
Milwus parasiticus—differs from specimens received from South- 
ern Africa only in being slightly less and in the tint of the 
plumage being more sombre. Old Calabar river.
