and has a more southern range. It may be questioned whether the 
two are distinct. Is not this a case of exception to our author’s 
favourite theory that our Mollusca attain larger development in 
northern latitudes ? 
Nassa nitida, Jeffreys. The Harwich Nassa, which has hitherto 
been regarded (and, we think, rightly) as a variety of WV. reticulata. 
Columbella halieeti, Jeffreys. An interesting species from the 
Shetland Haaf. 
Defrancia reticulata, Renier. Rare, but ranging from the Channel 
Islands to Shetland. A white variety of this species is the Mangelia 
purpurea, var. asperrima, of F. & H.; one of the loveliest of British 
shells. 
Pleurotoma rugulosa, Philippi. Cornwall. Perhaps scarcely 
sufficiently distinct from P. costata. : 
P. levigata, Philippi. Of southern and south-western range. 
Regarded by Forbes and Hanley as a variety of P. nebula. 
P. nivalis, Lovén. A very fine Norwegian species, of which a 
few examples have been dredged on the Shetland Haaf. 
Cylichna alba, Brown. A fine addition to our fauna from Shet- 
land. 
Utriculus ventrosus, Jeffreys. Only one specimen known, dredged 
by Mr. Barlee in the Sound of Skye. 
U. expansus, Jeffreys. Another Shetland treasure; and the 
‘Annals’.of last month records a third addition to this genus, also 
from Shetland, Utriculus globosus, Lovén, which has been discovered 
by the Shetland Dredging Committee, during the past summer, in 
St. Magnus Bay. 
Philine angulata, Jeffreys. Antrim, Hebrides, Shetland, and 
Aberdeenshire. 
P. nitida, Jeffreys. Skye and Haroldswick Bay, Shetland. 
These are not inconsiderable additions to have been made to our 
fauna in this best-worked-up department of marine zoology during 
the few years which have elapsed since the publication of Forbes 
and Hanley’s ‘ History.’ 
The observations which follow the descriptions of the species are 
always of value, and often very full and interesting. We are fre- 
quently astonished at the mass of information here briefly condensed. 
It has been Mr. Jeffreys’s aim to popularize his subject and to make 
a readable book. In the former volumes there were to be found 
frequent digressions from the direct history of the species on which 
he was writing, and the pages were thickly strewn with poetical — 
quotations. In the present volume such quotations and digressions, 
which were tiresome to the scientific reader, are much less frequent ; 
and, the space thus gained being filled with yet larger stores of © 
scientific information, the result is an increase, not a diminution, of 
interest. Such bibliographical and biological notes as we find, for — 
example, on Ianthina, Purpura, or Buccinum require no extraneous — 
accretions to set them off; they are replete with instruction and in- 
terest in themselves. |
