154  Dr.J. E. Gray on the Skull of Balena marginata. 
Iris brownish yellow; rictus and eyelids bright yellow. 
Upper mandible and tip of lower black, rest of lower mandible 
ight green; inside of mouth yellow. Legs orange-yellow ; 
claws brown, with black ridges. 
'l'his species stands midway between the true cuckoos and 
Hierococcyx. We found it abundant at Szechuen (Western 
China) in May. It is very noisy, flying excitedly from tree 
to tree, uttering its loud notes, which may be syllabled có/ó- 
tóló. 
To Mr. Alexander Michie of Shanghai, for the kind assist- 
ance he gave me in the pursuit of natural history on the 
Upper Yangtsze, I dedicate this species. 
Henicurus leucoschistus, sp. nov. 
n 
inwards, has the basal third of the quills edged on the inner 
web with white, commencing with the fourth quill. 
Inhabits the hills of Southern China. 
XII.—Notes on the Skull of Baleena marginata, the type of a 
new Genus, Neobalena. By Dr. J. E. Gray, F.R.S. &c. 
In the essay on Whales published in the ‘ Voyage of the 
Erebus and Terror’ I established a species of true Whalebone- 
Whale on three examples of whalebone which I had received 
from Western Australia, believing it to belong to the same 
genus as the Greenland Whale (Balena), as the whalebone 
was of long slender shape, and of a very fine texture, with a 
large quantity of enamel, which is a peculiarity of the baleen 
of that genus. Sir George Grey, the late Governor of New 
Zealand, has obtained the skull of Balena marginata from the 
island of Kawan, New Zealand, and has presented it to the 
Museum at Wellington. Dr. Hector has given figures exhi- 
biting four views of this skull in the ‘ Transactions and Pro- 
ceedings of the New-Zealand Institute’ for 1869, vol. ii., 
which was issued in April 1870. These figures show that the 
whale, which has long, slender, and fine-textured whalebone 
or baleen like that of the Greenland Right Whale, forms a very 
different genus from the restricted genus Balena. The brain- 
cavity forms a much larger part of the skull; the beak is much
