FORTY-SECOND ANNUAL REPORT, FOR I903. 



ir 



This added to the species of York N.W. Vice-County. The 

 specimens were the most richly coloured and characteristic 

 examples of var. rnfescens that Mr. Roebuck had ever seen. 



The WharnclifFe expedition yielded better results than the 

 previous visits to that locality, but the neighbourhood is a 

 vv'ilderness for molluscan research, Hyalinia excavata being the 

 only find of any note, and of that only one specimen was found. 



In May, three members of the Union, Mr. Cash, Mr. T. 

 Sheppard, and Rev. E. P. Blackburn, took in Tetney drain 

 (Lines.) a number of fine specimens of Amphipeplea glntinosa in 

 the same spot where Mr. Wallis Kew and Mr. Roebuck had 

 found them previously. 



During the past year, Physa heterostropha (an American 

 species) has been found near Huddersfield, by Mr. Thos. Castle, 

 of Heckmondwike, and has been verified by Mr. Wm. Nelson. 

 This constitutes a new record for Yorkshire, though it has been 

 found in one or two other counties. 



In connection with the Hull Scientific Club's Survey of 

 Hornsea Mere, much good work has been done by various 

 members. One expedition, when Messrs, Roebuck, J. W. 

 Taylor, J. D. Butterell, W. Cash, E. P. Blackburn, and others 

 were present, was successful in adding two or three species not 

 previously recorded. The flooded character of the Mere all 

 through the summer hindered better work. The survey is to 

 be continued again next year. 



A List of MoUusca of the Parish of Halifax has been 

 published in the " Halifax Naturalist " by Mr. J. E. Crowther, 

 and in the " Transactions of the Hull Scientific Club," a paper 

 on " Holderness Ponds," by Mr. T. Petch, B.Sc, B.A., and 

 " Some Notes on Wold Ponds and Carriage of MoUusca by 

 Water Insects," by Rev. E. P. Blackburn. 



It is recommended that the following be elected for 1904 : — 



President — Rev. E. P. Blackburn. 

 Secretaries — J. E. Crowther and T. Castle. 

 Representative on Executive — -J. E. Crowther. 



Botanical Section (Phanerogams). — Mr. J. F. Robinson 

 writes : — Notwithstanding certain meteorological disadvantages 

 under which, perhaps, all sections have laboured during the past 

 year, one or more members of the Committee have attended at 

 every excursion of the Union ; and they have seen or heard of 

 good work being done amongst the Phanerogams. Some old, 

 or doubtful, stations of certain plants have been confirmed, as in 

 the case of Geranium sanguineuin ; new stations have been found
