520 NOTES AND EXHIBITS. 



Mr. Henn exhibited, on behalf of Mrs. G. J. Waterhouse, a 

 very fine collection of Cyjyrceidoi, 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 : — Cyjorcea Jimbriata, Gmelin, 

 C. macula, A. Ad., C. felina, Gmelin, C. assellus, Linn., C. 

 tabescens, Solander, C. arabica, Linn., C. moneta, Linn., C. 

 annul us, Linn., C. cajyut-serpentis, Linn., C. helvola, Linn., C. 

 clandestina, Linn., C. flaveola, Linn., C. lutea, Gronovius, C. 

 comptoni, Gray, C. errosa, Linn., C. err ones, Linn., and C. inter- 

 punctata, Brazier, MS. The last, (of which two specimens were 

 found) difiers from C. 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. interpunctata. Brazier. 



Of the above, no less than nine species, viz : C. Jimbriata, 

 tabescens, arabica, moneta, helvola, flaveola, lutea, comjjtoni, and 

 interpunctata, have never been previously recorded from Port 

 Jackson. The Cyprceidce 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 G. 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.
