184 The Victoria History of Yorkshire. 
to Filey Brig, Flamborough Head, or other suitable points. 
Probably something in this direction will be accomplished 
during the coming summer. 
The account of the non-marine mollusca of the county seems 
very brief indeed, occupying four-and-a-half pages only. This 
is probably due to the fact that it has been- prepared by Mr. B. 
B. Woodward, of the British Museum, who naturally cannot be 
familiar with the district he is describing, as are at least half-a- 
dozen prominent conchologists in the county. Perhaps the 
omission from the list of contributors to the present volume of 
the names of undoubtedly the best qualified conchologists in 
Yorkshire, we had almost said Britain, is the greatest surprise 
we have had in perusing it. Mr. Woodward points out that of 
the 146 species of non-marine mollusca now known to inhabit 
the British Isles no fewer than 122 have been recorded from York- 
shire. He regrets that there is, as yet, no complete memoir 
dealing with the land and fresh-water shells of the county as a 
whole, and this regret we certainly share with him. He points 
out that such a list was begun by Taylor and Nelson, in 1877, in 
the ‘Transactions of the Yorkshire Naturalists’ Union,’ but it 
remains a fragment. We believe the conchological section of 
the Union is now considering the question of the completion of 
this list, and the sooner this appears the better. Possibly, had 
it existed, Mr. Woodward’s contribution to the Victoria History 
would have been more substantial. It is gratifying to notice 
that ‘the compilation by Mr. T. Petch of a published record of 
the land and fresh-water mollusca of the East Riding, with 
additions (Trans. Hull Sci. and F. Nat, Club, iii., 121-181), is 
the best planned local list it has been his good fortune to meet 
with, especially in the matter of the maps, and it is a great pity 
it has not been extended to the whole county.’ 
Dealing with the insects there is a very satisfactory con- 
tribution of eighty pages, under the general editorship of Mr. 
G. T. Porritt, who has supplied the lists of Orthoptera, 
Neuroptera, Trichoptera, and Lepidoptera.* Mr. Denison 
Roebuck is responsible for the Hymenoptera, Messrs. E. G. 
Bayford and M. L. Thompson for the Coleoptera, and Mr. P. 
H. Grimshaw for the Diptera. There does not appear to be a 
* The list of Lepidoptera contains the following records, which have 
been made since the second edition of Mr. Porritt’s ‘List of Yorkshire 
Lepidoptera’ appeared :—Plusia moneta, Euchromia mygindana, Orthotenia 
antiguana, Catoptria fulvana, Acidalia emutaria, Ephippiphora grandevana, 
Gelechia atriplicella, Bedellia somnulentella.
