March 23, 1841. 
William Yarrell, Esq., Vice-President, in the Chair. 
A collection of birds from Newfoundland, presented by E. Moore, 
Esq., was exhibited: it consists of specimens, in different states of 
plumage, of the Willow Ptarmigan (Tetrao Saliceti), a specimen of 
the Pin-tailed Duck (Dajila caudacuta), the American Teal (Querque- 
dula Americana), and the Black-backed Gull (Larus marinus). 'The 
collection also contains a foetal Esquimaux preserved in spirit. 
A paper by G. B. Sowerby, Esq., was read, in which the author 
proceeds with his descriptions of the new species of shells collected 
by H. Cuming, Esq., in the Philippine Islands. The following 
species were described and exhibited :— 
Hewix matrvuewis. Hel. testd depressiusculo-subglobosd, tenuius- 
culd, levi, castaned, epidermide opacd, pallescente, hydrophand 
indutd ; spird subdepressd, anfractibus quatuor subrotundatis, ul- 
timo maximo, ventricoso ; suturdé distincté ; aperturd subtrape- 
zoidali, extiis rotundatd, intits sinum prope columellam efformante, 
labio externo reflexo rotundato, fusco ; columella latiusculd, declivi, 
anticé oblique subtruncatd. 
Long. 1*1; lat. 1°6 poll. 
Hab. supra folia arborum propé Cagayan, Provinciz Misamis, In- 
sule Mindanao, Philippinarum. 
Obs. Variat interdim spirdé minus depressd. 
Of this species there are two varieties in form and several in 
colouring. ‘The variety with a rather more than usually elevated 
spire very closely resembles some of the varieties of Helix Roissyana ; 
still it may be distinguished from that species by the much greater 
declivity of the columella, and its broader and less rounded outer 
lip. In the general arrangement of the colouring all the varieties 
are somewhat similar, particularly in the dark chestnut colour of the 
apex, which is continuous down the anterior part of the following 
volutions ; the upper part of the second and third volutions are 
lighter ; the columella is dark brown, and there is always a very 
light band surrounding it, which when covered with its epidermis is 
light yellow-brown, but when deprived of it is white; this is sur- 
rounded by a very dark brown band. The following are the varieties 
in colour, viz. 
a. Shell with a dark brown band at the periphery and another 
antesutural dark brown band; epidermis with a very pale band at 
the circumference. 
6. Shell coloured precisely like a.: epidermis with a very dark 
band at the circumference.
