In our former series we represented, this species as it is 

 usually seen ; our present figures were drawn from a very 

 uncommon variety, received by Mrs. Mawe from Brazil, 

 in which not the slightest appearance of the external trans- 

 verse bands are apparent. The specimen now forms a part 

 of the valuable and extensive Museum of the Natural His- 

 tory Society of Manchester ; a collection which we believe 

 is superior to that of any provincial town in the kingdom. 

 It is gratifying to us to inform the scientific student, that 

 its contents will be thrown open to his enquiries with a 

 promptitude and liberality, which he will in vain look for 

 at some of the Zoological Institutions of the metropolis. 



Our friend Henry Parker, Esq. of Liverpool, who while 

 prosecuting his botanical researches in Demerara, was not 

 unmindful of conchology, favoured us with an interesting 

 series of specimens from that river, clearly shewing that 

 the X. fasciata and canaliculata of Lamarck are varieties 

 of one species ; or rather, that there are specimens of fasci- 

 ata which perfectly agree with his description of canali- 

 culata. We further learn from Mr. Parker, that the inha- 

 bitant of this, and of other species, are a favourite food with 

 the crafty Herons, who use their bill as a spear to take them 

 from the bottom ; in some places, the banks of the river 

 are strewed with empty shells, all perforated by these birds.
