the genera ; yet at page 1 14 we find a division (a far more satisfactory 

 division, to our mind, than that of Forbes and Hanley) of the species 

 into three sections, for which the generic names might have been 

 advantageously retained. The name Odostomia is altogether inap- 

 propriate to the tootliless forms of Chemnitzia and Eulimella. 



The volume contains descriptions of one hundred and eighty-two 

 species ; whereas Forbes and Hanley, in the same families, give only 

 one hundred and sixty-nine ; but, inasmuch as sixteen of the forms 

 described by the latter are here struck out of our fauna, we find that 

 an addition has been made to this section of our MoUusca of no less 

 than twenty-nine species since the pubhcation of the ' History of the 

 British MoUusca.' The sixteen expunged forms are : — lanthina 

 eccigua, Bruguiere, awA pallida, Harvey, as not having been found 

 alive upon our coasts ; Scaloria groenlandica, fossil ; Natica Kingii, 

 Forbes, as an exotic freshwater species erroneously recorded ; La- 

 mellaria tentaculata, Montagu, as being the male of L. perspicua, 

 Linn. ; Cylichna conulus, S. Wood, and strigeUa, Lovt'n, as synony- 

 mous with C strigeUa ; together with the nine Odostmnice, Chem- 

 nitzi(S, and EulimeUce already referred to. 



The following are the twenty-nine species which are here described 

 as inhabitants of the British seas, but which have no place in the 

 work of Forbes and Hanley : — 



Rissoa Jeffreysii, Waller. Shetland. 



R. ulbella, Loven. This is the R. inconspicua, var. tenuis, of 

 Forbes and Hanley. It has been found at Southampton and on 

 various parts of the western coast, and at Shetland. 



Aclis TFalleri, Jeffreys. Deep sea, Shetland. 



Odostomia minima, Jeffreys. Guernsey, Falmouth, Hebrides, and 

 Shetland. 



Odostomia Lukisi, Jeffreys. 1 



O. alhella, Loven. I Each of these species has been 



O. diaphana, Jeffreys. [found in several locaUties. 



O. umbilicaris, Malm. J 



Eulima intermedia, Cantraine. Widely distributed. 



E. stenostoma, Jeffreys. The Haaf, Shetland. 



Torellia vestita, Jeffreys. A single dead specimen on east coast 

 of Shetland. 



Cerithiop)sis Barleei, Jeffreys. Plymouth, Falmouth, Cork, and 

 Galway. 



C. pulchella, Jeffreys. Guernsey, Devon, Cornwall, and Antrim. 



C. costulata, Moller. Deep water, Shetland. 



Triton nodij'er, Lamarck, and T. ciitaceus, Linn. Guernsey. 

 Two very fine Mediterranean forms. 



Fitsus Islandicus, Chemnitz. Two specimens from the Shetland 

 Haaf and one from Wexford. This is the typical Islandicus, a much 

 finer species than that described by Forbes and Hanley under that 

 name, which in Mr. Jeffreys's work is called F. gracilis. Da Costa. 



Fusus buccinatus, Lamarck. Allied to F. 2Jropin(pms,vi'\t\\\y\\ich. 

 it has hitherto been confounded. It is a much larger and coarser form,
