been taken in both the northern counties ; and another species found 
there is of great interest, inasmuch as it was first described as a 
tertiary specimen by Rupert Jones, but has since been discovered in 
brackish water at Gravesend, and at Warkworth. 
The British Association, at its Cambridge meeting, renewed a 
grant for dredging the Dogger Bank, and the coasts of Northumber- 
land and Durham. These explorations have resulted in several 
interesting and new forms, including a beautiful nudibranchiate 
mollusk (Hero formosa, Lovén), which occurs on the coasts of Norway 
and Sweden. The Durham coast, however, is described as generally 
poor in Mollusca, which have a boreal type, approaching more nearly 
to the Scandinavian than to the South of England fauna. Mr. Alder 
gives a report upon these, while Rev, A. M. Norman reports upon the 
Crustacea, which includes specimens of Sacculina and Peltogaster, 
rare forms which are found parasitic upon the abdomen of various 
stalk-eyed Crustacea. The Echinodermata yielded a rich return, 
including a new species (Ophiura squamosa, Liitken), and Mr. Alder 
describes among the collection of Zoophytes a new Scrupocellaria 
(Delilii), and other remarkable forms. 
In further proof of what we have observed concerning the working 
of this provincial Society, we must also refer to Mr. Hodge’s list of 
the British Pycnogons (Araneoid crustacea), in which thirty-two 
species are included, ten of which are new. These are described and 
figured by the author. 
‘The Woolhope Naturalists’ Field Club’ principally employs 
itself with the Natural History of Herefordshire ; and the fifth num- 
ber of its Transactions is chiefly occupied with an elaborate and 
exhaustive treatise on the ‘Mistletoe in Herefordshire,’ by Dr. Bull. 
This paper contains a great amount of information concerning this 
interesting parasite—the mode of its propagation and growth—the 
trees it lives upon in this country—the recorded history of its growth 
on the oak in England—and the romance of its history as developed 
in times past and present. Thirty trees are mentioned as bearing 
mistletoe, including apple, seven species of poplar, hawthorn, crab, 
lime, maple, acacia, flowering-ash, willow, hazel, alder, sycamore, elm, 
horse-chestnut, &c.; but the favourite site of the mistletoe is certainly 
the apple-tree. The actual numbers were 784 trees with mistletoe, and 
1,218 without it—or from other sources, a general average of 34 per 
cent. Mistletoe is never seen to grow spontaneously upon the beech, 
birch, bird cherry, wild cherry, sloe, hornbeam, elder, holly, dog- 
wood, box, Lombardy poplar, sweet-chestnut, walnut, laurel, nor on any 
other of the many introduced varieties of trees and evergreens. Only 
six well-authenticated instances are recorded of its growing upon the 
oak, throughout England, although others have been noticed which 
were either erroneous or have now ceased to exist. 
‘The Devonshire Association for the Advancement of Science, 
Literature, and Art,’ held its third Annual Meeting in July at 
Torquay, under the presidency of Mr. Vivian, and after an inaugural 
address, several papers of considerable interest were read, among 
which were :
