the genera ; vet at page 114 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 toothless forms of Chemnitzia and Lulimella. 
_ 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 Mollusca of no less 
than twenty-nine species since the publication of the ‘ History of the 
British Mollusca.’ The sixteen expunged forms are :—Ianthina 
exigua, Bruguiére, and pallida, Harvey, as not having been found 
_ alive upon our coasts; Scalaria grenlandica, fossil; Natica Kingit, 
Forbes, as an exotic freshwater species erroneously recorded ; La- 
mellaria tentaculata, Montagu, as being the male of L. perspicua, 
Linn. ; Cylichna conulus, 8. Wood, and strigelia, Lovén, as synony- 
mous with C. strigella; together with the nine Odostomie, Chem- 
nitzie, and Eulimelle 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. albella, Lovén. ‘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 Walleri, Jeffreys. Deep sea, Shetland. 
Odostomia minima, Jeffreys. Guernsey, Falmouth, Hebrides, and 
Shetland. 
' Odostomia Lukisi, Jeffreys. 
O. albella, Lovén. Each of these species has been 
O. diaphana, Jeffreys. found in several localities. 
O. umbilicaris, Malm. 
_ Hulima intermedia, Cantraine. Widely distributed. 
E. stenostoma, Jeffreys. The Haaf, Shetland. 
Torellia vestita, Jeffreys. A single dead specimen on east coast 
of Shetland. 
Cerithiopsis Barleei, Jeffreys. Plymouth, Falmouth, Cork, and 
Galway. 
C. pulchella, Jeffreys. Guernsey, Devon, Cornwall, and Antrim. 
C. costulata, Moller. Deep water, Shetland. 
Triton nodifer, Lamarck, and T. cutaceus, Linn. Guernsey. 
Two very fine Mediterranean forms. 
Fusus Islandicus, Chemnitz. Two specimens from the Shetland 
Haaf and one from Wexford. This is the typical Is/andicus, 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. propinguus, with which 
it has hitherto been confounded. It is a much larger and coarser form,
