NOTICES TO MEMBERS. 
One of the chief objects which the Club had in view at its formation, was the 
preparation of Catalogues of the Fauna and Flora of the Counties of Northumber- 
Jand and Durham; much has already been done, but much yet remains to be 
accomplished. The following Catalogues are at the present time in the hands of 
competent members, who invite the assistance and co-operation of others who 
are pursuing the same studies. 
Mammatta.—Henry T. Mennell, and Vincent R. Perkins. In this class, the 
Bats and Shrews are probably the least known, and specimens of either 
will be most acceptable. Information respecting the occurrence of Cetacea 
on our shores, and lists of the animals found in particular districts will also 
be of very great assistance. 
OrNITHOLOGY.—John Hancock. Notices of the occurrence of rare Birds in the 
district should be forwarded. 
Fossin Fis, &c.—1t is the intention of Mr. Thos. Atthey (Cramlington), and 
Mr. J. W. Kirkby (Sunderland), to describe in the Transactions, some 
Animal Fossils that have been found in the coal measures at Cramlington 
and Ryhope; they are desirous of obtaining information of the occurrence 
of similar Fossils in other parts of the Northumberland and Durham Coal- 
field. The greater part of the materials which they propose describing have 
been collected by Mr. Atthey from the roof of the Low Main, and their 
abundance in the localities he has searched, renders it extremely probable 
that the distribution of such remains will prove to be wider than existing 
information will allow us to assert. They would therefore invite attention 
to the subject, more particularly the attention of those members who have 
opportunities of pursuing observations in colliery districts, and who may be 
willing to assist in our attaining an improved knowledge of the creatures 
that peopled this region during the formation of the coal and the deposition 
of the associated strata. The remains most likely to occur are those of 
Fisu, ¢eeth, scales, and bones, possibly reptilian remains and mollusca, 
Any member possessed of, and willing to impart information of this kind, 
may communicate with the gentlemen above named, either directly or 
through the Secretaries of the Club. 
Crustacea.—Rev. Alfred Merle Norman, M.A., Sedgefield. 
EcHINODERMATA.—Mr. George Hodge, Seaham Harbour. 
InsEcts.—Lepidoptera—Myr. George Wailes, Newcastle-on-Tyne. 
Coleoptera—Mr. Thomas J. Bold, Long Benton, near Newcastle- 
on<yne. 
Hymenoptera, &c.—Mr. Thomas J. Bold, and Mr. Vincent R. 
Perkins. 
Hemiptera.—Mr. T. J. Bold and Mr. Perkins have been for some 
time past busily engaged in collecting the local species 
of Hemiptera, or Bugs, and they will be greatly 
obliged to any of the members who will assist them 
in collecting these insects on the days of the Field 
Meetings or otherwise. All specimens forwarded to 
them shall be correctly named, and kept at their cap- 
tor’s disposal, and any standing in old local collec- 
tions shall be carefully examined and returned with 
the names attached.
