in Burmah. Of the closely allied genus Vaginulus, Mr. W. Theobald had 

 described one species from Burmah, and Mr. Gr. Nevill lately obtained 

 near Calcutta two small specimens of apparently the same species. 



Mr. W. Blanford said that the study of the animals of the various 

 Molluscs and especially those of Onchidium, was of the highest impor- 

 tance, and that he had no doubt that Dr. Stoliczka's labours in this line 

 would be highly appreciated by conchologists. He had himself observed, 

 he believed, at least two Indian species of Onchidium beside those 

 mentioned by Dr. Stoliczka. All the Onchidia were found along the 

 seashore or on the banks of tidal rivers, while the species of Yaginulus 

 appeared to be terrestrial animals. 



Dr. Stoliczka mentioned that the errors which had been made by 

 former observers were chiefly due to the difficulty in preserving animals. 

 Since Dr. Buchannan, only very few naturalists had the opportunity 

 of examining live animals, and those preserved in spirit easily change 

 their form so much, that it was extremely difficult satisfactorily to trace 

 out the structure and the position of some of the internal organs. 



Dr. Stoliczka also brought to the notice of the Meeting a paper 

 entitled " Remarks on the species of the genus Pandanus ; by S. 

 Kurz, Esq. 



The object of the paper was a somewhat different grouping of the 

 species of Pandanus from that recorded in botanical works up to the 

 present date. Mr. Kurz divides the known species of Pandanus into 

 five sections, — which may be said to have sub-generic value, — under 

 the names Acrostigma, Byckia, Keura, Microstigma and Souleijetia. 

 Short characteristics of the various sections are given, and 27 species 

 are enumerated in his list. 



Papers received from the Public Works Department, reporting the 

 occurrence of earthquakes in June last, were laid before the Society. 



The Superintending Engineer of South-East Circle, Mr. Leonard, 

 reports that " A shock of earthquake was felt at Sylhet at a few minutes 

 past 12 o'clock, on the morning of the 30th June (29th-30th). There 

 \ were three waves, rather abrupt, the second so much so as to shake 

 the furniture." The shocks occupied about half a minute, and a tre- 

 mulous motion continued for half a minute more in the direction of 

 west-south-west to east-south-east. Slight shocks were also felt at
