114 Address to the Lincolnshive Naturalists’ Union. 
In 1898, the long-wanted Cecilioides acicula was added to our 
list by Mr. J. H. Cooke. This is what is called the Needle 
Agate Shell, from its shape and colour, it is blind and lives in 
the earth, just beneath the surface-crust, especially in limestone 
and chalky areas. 
The same year, Mr. F. M. Burton found at Gainsborough 
Testacella haliotidea, the shell-bearing carnivorous slug, which 
is also an underground creature, preying upon worms. 
In 1900, Mr. Kew added Pisidium amnicum to our fauna. 
In 1go0, there appeared on the scene a new worker, Mr. C. 
S. Carter, of Louth, one of the most vigorous and indefatigable 
workers the county has ever had. His sound and competent 
knowledge of geology and the acumen he has displayed in his 
malacological investigations have contributed much to the 
advancement of our study. Vertigo angustioy was added by him 
during his first year’s collecting, Prsidium milium during the next 
year and various other species since. His minute and detailed 
investigations of the molluscan fauna of the Hubbard’s Hills, 
near Louth, are of permanent value and a model of what detailed 
local work by a resident should be. His notes on the albinism 
of about ten species in that district are particularly interesting, 
and his lists of the holocene fossil shells found in the rainwash 
there, valuable. 
In 1901, the Rev. E. A. Woodruffe-Peacock, who had 
previously confined his attention to the flora of the county, took 
up the active pursuit of the Lincolnshire molluscs with his 
characteristic vigour and energy, and with good results. He 
verified the species indicated in Mr. Ball's Brigg list, he paid 
special attention to the mollusca of the thrush-stones—and his 
special and technical knowledge of soils and soil-preferences 
make his papers of much value to us in our work. In igor, he 
added the rare slug Limax cinereo-niger to our list. 
In 1902, Mr. H. Wallis Kew published in “‘ The Naturalist” 
a new list, arranged according to the most recent classification, 
and accompanied by a bibliography of the books and papers 
containing the successive additions to the ‘Lincolnshire list. 
The total number of Lincolnshire species is here brought up to
