single vessel being 32,000. Amongst the six Duiulee vessels the 
produce of the voyage was more evenly distributed than in 1882, 
and the average reached 15,000; but if it be correct that it ro(|uires 
precisely that number of Seals to pay the expenses of one of these 
costly vessels, the voyage cannot bo considered, commercially, a 
very successful one, notwithstanding the enormous number of Seals 
killed. It seems impossible, vast as are the packs of breeding Seals 
M-hich visit the ice-fields of Newfoundland, that they can long 
survive the yearly attacks made upon them, the results of which 
are very inaderpiately represented by the published returns 
(see ]). 499), .and that too at .a period when (piiet and retirement 
are so necessary to the duo fulfilment of the functions of i-eproduc- 
tion, and it cannot fail ere long to produce a perceptible effect on 
their number.s. The turning-point once psissed, the Newfoundhand 
fishery must soon, like that of the Greenland seas, bo utterly 
ruined.

Among the ilollusca recently found in the 'VVeybourn Crag of

deserves more than a p.assing notice. They possess the’rimate 
umbilicus, and other ch.aracters, which separate the genus Lithoghj- 
pirns from the other Littonnidce ; and on comparing the fossil shells 
with the recent L. fuscus from the Danube, in the British Museum, 
neither J\lr. Edg.ar Smith nor myself M*ere able to detect an\' 
flifTerence, except that the "W eybourn Crag specimens .are rather
