NOTES AND EXHIBITS. 
Mr. Henn exhibited, on behalf of Mrs. G. J. Waterhouse, a 
very fine collection of Gyprceidce, found alive by herself and sons 
in Port Jackson, between the months of May and August of this 
year. The collection consisted of exactly 100 specimens belonging 
to the seventeen following species: — Cyprcea fimbriata, Gmelin, 
G. macula, A. Ad., C. felina, Gmelin, C. assellus, Linn., G. 
tabescens, Solander, C. arabica, Linn., C. moneta, Linn., G. 
annulus, Linn., G. caput-serpentis, Linn., C. helvola, Linn., C. 
clandestina, Linn., C. Jlaveola, Linn., C. lutea, Gronovius, C. 
comptoni, Gray, C. errosa, Linn., C. err ones, Linn., and G. inter- 
punctata, Brazier, MS. The last, (of which two specimens were 
found) differs from G. macula, — which it otherwise much resembles 
— in being more pyriform, and much more profusely and distinctly 
marked with spots. It is considered by Mr. Brazier to be a dis- 
tinct new species, but it would, perhaps, be more correctly described 
as C. macula, A. Ad., var. inter punctata, Brazier. 
Of the above, no less than nine species, viz : G. fimbriata, 
tabescens, arabica, moneta, helvola, Jlaveola, lutea, comptoni, and 
interpunctata, have never been previously recorded from Port 
Jackson. The Cyprceidai are amongst the rarest shells in the 
harbour, and very few — even dead — specimens have come to light 
for some years past. It is all the more remarkable therefore that 
so large a number of species should suddenly be discovered. They 
were found under stones rather below extreme low water mark 
and, with two exceptions, all within a radius of one hundred 
yards. In addition to the above, Mrs. Waterhouse also found 
dead specimens of C. caput-anguis and C. hirundo in very good 
condition, neither of which has been previously recorded from Port 
Jackson. 
Mr. Henn also exhibited three extremely fine specimens of C. 
vitellus, Linn., and a specimen of Micromelo guamensis, Quoy et 
Gaimard, all found alive at Botany Heads by Mr. Norman 
Hansard in July. The latter very beautiful little shell has never 
been recorded from Australia previously, but is a native of the 
South Sea Islands.
