PART II 



TAENIOGLOSSA and PTENOGLOSSA 



This part contains the enumeration of about 340 species, of which 39 have been 

 described as new to science, moreover a few varieties have been described and partly figured. 

 By comparing these numbers to those of the first part, it is evident that this first part was 

 more interesting, the groups now under consideration not being composed of so many deep 

 water forms, and it is amongst those, as might be expected, that the most interesting species 

 are to be found, as for instance in the genera Morio, Oocorys, Segaenzia. 



I have to thank again Mr. E. A. Smith for his assistance in comparing doubtful species 

 also Messrs. J. Cosmo Melvill, Pii. Dautzenberg, E. R. Sykes and others, for assistance, loan 

 of specimens or litterature. 



I must repair a few errata in the first part, which I discovered in returning the materials : 

 p. 10. var. strigillata belongs to N. turrita not to variegata. 



p. 13. the Ncritilidac must follow after Septaria, which belongs to the Neritidae. 

 p. 71. for Euchchts iutricatus Gould read Etich. instrictus.
