Papers.—(1) ‘‘ Notes on a skeleton of the hump-backed 
whale, Megaptera lalandu (Nove Zelandie), Gray,’ by Prof. J. von 
Haast, Ph.D., F.R.S. The author describes in this paper the 
complete skeleton of the New Zealand Humpback Whale, of which 
hitherto portions were only known. It was named by the late 
Dr. Gray trom an earbone alone. Although small differences 
appear in the osteology of the New Zealand specimen when com- 
pared with drawings and descriptions of M. Lalandii (the Hump- 
back Whale ot the Cape of Good Hope), described and figured by 
Van Beneder and Gervais in their Ostéographie des Cétaceés, 
there is, according to the author, no doubt that the New Zealand 
specimen is identical with the former, and that thus Megaptera 
Novee-Zcelandice has to be abolished. Drawings of the sternum 
- and scapula are added in illustrations. 
2. ‘On the Silt Deposit at Lyttelton,” by Professor Hutton. 
This paper drew attention to a section made by cutting back the 
hill to form a site for the Lyttelton Dock, which showed that the 
silt deposit was here distinctly stratified, and dipped 15deg. N.E. 
The author was of opinion that this stratification could not be 
explained on the theory of the sub-aerial origin of the deposit, as 
advocated by Dr. von Haast. The stratification can be seen from 
the steamer pier in Lyttelton Harbour. 
3. ‘Additions to the Isopodan Fauna of New Zealand,” by 
Charles Chilton, B.A. In this paper two species were added to 
the New Zealand Isopoda :—(1) Apseudes timaruvia, sp. nov., from 
Timaru. This species was described at some length, and nume- 
rous figures were given of its different parts. It hasan appendage 
to the second maxilla somewhat like that of Tanais, which may — 
perform the same function, for the pleopoda are small, and do not ~ 
look like respiratory organs. (2) Philougrea vosea, Koch.—A Euro- 
pean species, specimens of which were found at Christchurch, 
and also at Eyreton. Perhaps introduced from England.
