the beach of Santa Cruz Island in 1897, and presented by him to 
the Trustees. So unlike any other described species does it 
appear that 1 have considered that even such imperfect material 
should be utilised. 
The brothers Adams, in grouping the recent species of Lima , 
set apart under the subgenus Ctenoides of Klein, L. scabra , Born, 
and L. tenera , Chemnitz, distinguished, among other features, by 
a sculpture of “ ribs divaricate, meeting in jthe centre.” Our 
novelty appears to find its nearest relations with these. More 
recently described species embraced by this character are -Z. 
cdbicoma , Dali., L. concentrica , Sowerby, and L . nmrrayi, Smith. 
L. alata appears to be longer than any of its immediate kin, 
with which I am not au topically acquainted, and to differ liom 
any recent Lima in the development and sinuation of the anterior 
auricle.

For nearly a quarter of a century various observers and writers 
have made reference to a species of Pigeon frequenting the Ellice 
Group. As I pointed out in my brief notes on the birds brought 
back from Funafuti by Mr. Hedley,* I could find no record of 
adult specimens having been obtained, but there was little doubt 
that the birds seen by Mr. Jansen on Funafuti in 1876, and by 
Mr. C. R. Swayne on Niu in 1895, were correctly identified by 
them as Globicera pacifica. 
Prior to the departure of the Coral-Boring Expedition for 
Funafuti last year, I urged the desirability of procuring one or
