THE publication of catalogues of the various natural productions of the 
counties of N orthumberland and Durham, was one of the chief objects 
of the originators of the Tyneside Naturalists’ Field Club. That it has 
never been lost sight of, the following list of catalogues already pub- 
lished in our Transactions fully shows :— 
Coleoptera, by Jas. Hardy and T. J. Bold. Lepidoptera, by Geor ge Wailes, 
Mollusca, by Joshua Alder. Marine Alge, by G. 5S. Brady. 
Permian Fossils, by R. Howse. Mammalia, by H. 'P. Mennell, F.L.S., and 
Zoophytes, by Joshua Alder. VY. R. Perkins. 
Several other catalogues are now in course of preparation, and the 
attention of members is requested to the following notes, in the hope 
that those who have opportunities of collecting specimens or information 
in any department, will, as far as possible, assist those naturalists who 
have undertaken the compilation of the catalogues, by the communica- 
tion either of specimens or observations. 
FLOWERING PLANTS AND FERNS; J. G. Baker, Thirsk. Lists of 
localities of the rarer species will be useful. In Watson’s “ Cybele 
Britannica,” the two counties of Northumberland and Durham make up 
one of the eighteen “‘ provinces” into which Britain is divided. This is 
sub-divided into three ‘‘sub-provinces,” which it is proposed to call 
Cheviotland, Tyneland, and Durham. The first includes the tract 
drained by the Coquet and the streams on the north of it; the second the 
remaining portion of Northumberland; and the third just corresponds 
with the county of Durham, exclusive of the outlying tracts on the north 
of the Tyne. In the Cybele six zones of climate are defined, and 
the plants traced through them. Beginning to count at the warmest, 
the second, third, and fourth, but not the first, fifth, and sixth, come 
within our limits. Mr. Baker proposes to regard the contour lines of 300 
and 600 yards as the boundaries between the three zones in our own 
counties, and will be particularly glad of any information respecting 
the heights of those tracts not yet mapped by the Ordnance Survey. 
The list of species for the middle zone is extremely incomplete; for the 
upper one is still almost entirely wanting. /wbus isthe genus respecting 
which information is most deficient, especially for Cheviotland and 
Durham. 
FRESH WATER ALG; George S. Brady, Sunderland. 
Any specimens of these, especially from the streams and ponds in our 
upland districts, bogs, and moors, will be valuable. They should be sent 
either as gathered, in a little clear water, or carefully dried upon paper. 
FORAMINIFERA; H. B. Brady, F.L.S., Gateshead. 
ECHINODERMATA; George Hodge, Seaham Harbour. 
ANNELIDA; George S. Brady, Sunderland. 
CRUSTACEA; Rev. A. M. Norman, M.A., Herrington. 
LEPIDOPTERA; George Wailes, Gateshead. 
CoLEOPTERA; 7. J. Bold, Long Benton, near Newcastle. 
HYMENOPTERA; 7. J. Bold. 
HEMIPTERA; Z. J. Bold. 
Specimens of the bugs infesting plants will be acceptable. Almost 
each plant has its peculiar species of bug; and botanists, at our field 
meetings and other times, might do good service by collecting and 
forwarding them to Mr. Bold. 
Birps; John Hancock, Newcastle. 
Notices of the occurence of rare species should be forwarded. 
Fossit FisH, &c.; J. W. Kirkby Ys Sunderland, anc Thomas Atthey, 
Gosforth. 
Mr. Kirkby will be glad of the opportunity of examining any fossil 
animal remains which may be found occuring in coal mines or elsewhere.
