July 13. — The Secretary exhibited specimens of several 

 new species of Cypraea, from the Cabinet of Mr. J. E. Gray, 

 which had been lately figured and described in the Zoological 

 Journal. In one of these, the C nivea, there appeared a singular 

 deviation from the colouring of the other Ct/prcecv^ in its being 

 perfectly free from those bands, which appear in greater or less 

 number upon the whole of the species hitherto described. A series 

 of Patella cceridea and P. pellucida was also exhibited, which 

 identified them as one species, differing in form, opacity, and 

 colour, according to the nature of the surface, whether fiat or 

 rounded, to which the shell is attached : as also a specimen 

 illustrative of the same fact, being an union of the Patella com" 

 jpressa and P. miniata ; an anomaly, which had been observed 

 by Lamarck with considerable surprise. The present specimen 

 exhibited at its apex the form of P. miniata^ in the middle that 

 of P. conipressa, and at its base it rea?sumed the character of 

 P» miniata. 



A portion of a paper " On the Flight of Insects," by J. 

 Chabrier, translated by Mr. Bennett, was read.

 Sty lops Melittce, one of which was taken in the spring of the
