Mr. Ouprie~tD Tsomas, F.R.S., F.Z.S., contributed a paper 
**On a remarkable Case of Affinity between Animals inhabiting 
Guiana, W. Africa, and the Malay Archipelago.” 
The case referred to was that of the Pygmy Squirrels (Vanno- 
sciurine), known to be natives of W. Africa and the Malay 
Archipelago, and of which Mr. Thomas was now able to state 
that the Guianan “ Sciwrus pusillus” was also a member. It was 
sufficiently distinct to need generic separation (Sciwrillus, gen. 
nov., was suggested as a name for it), but was unquestionably 
assignable to the Vannosciurine, and not to the Seciwrine, to 
which all the other American, all the European, and all the 
Asiatic continental Squirrels belonged. 
So rare and striking a case deserved prominent record, so that 
students of geographical distribution might have their attention 
directed to it. 
Mr. H. B. Preston, F.Z.S., presented a paper containing 
diagnoses of new genera and species of Zonitide from Hjuatorial 
Africa. The material on which the paper is based was recently 
collected from many localities in British Hast Africa, Uganda, 
and the Belgian Congo by Messrs. A. Blayney Percival, Robin 
Kemp, and C. W. Woodhouse, and descriptions are given of 
seventy-six new species, two new varieties, and eight new genera 
of Zonitide, to which latter a number of hitherto-described forms 
are also referrel; the author points out that, as far as the 
present collections show, scircely any of the South African 
generic nam2s in this group are applicable to the Central African 
species, and also that the various genera and species of the family 
do not seem to show peculiar local characters as is the case with 
the agnathous molluses from the same regions.
