ISTORY.—NVerophila neglecta was 
first discriminated, described, figured 
and named by Prof. Draparnaud about 
120 years ago, and was very generally 
accepted as a valid species, although Dr. 
Heynemann regarded it as a somewhat 
narrowly umbilicated form of Y. dtala ; 
while Comm. Caziot places this species 
along with more than a score of others 
as the type of a new group Neglectianu, 
arranging them into two sections. 
Dr. J. E. Gray more than seventy years 
ago, recorded that this species had been 
admitted into the British list by Dr. Gwyn 
Jeffreys, who regarded it as a variety of 
Nerophila virgutu. It has, however, been 
recently rediscovered in this country by 
Mr. A. 8. Kennard, who in September, 
1915, found specimens at Luddesdown, a 
Ae CE village on the chalk formation, near to 
Le Cobham in West Kent, where it still exists. 
os The precise locality is a remote spot 
about three-quarters-of-a-mile from, and 
south-west of the village church, and is a grassy bank, about six feet high, 
which is really a gap in a road-side hedgerow. ‘The species apparently 
continues to be restricted to the original spot, and judging from the dead 
shells to be seen around, must have existed there for many years. 
I have pleasure in associating this species with the late M. Arnould 
Locard, of Lyons, one of the most distinguished and typical of the 
enthusiastic group of continental analytical conchologists, who have for so 
many years intensively studied and minutely differentiated the shells of 
France and other countries. 
Moquin-T'andon figured the mandible, but little or no further progress 
was made until Prof. Boycott and Dr. Bowell examined the organization 
of the species, and it is to their studies that we are indebted for what 
little we know of its internal structure. 
Diagnosis.— EXTERNALLY, -Xerophila neglecta may be distinguished 
from X. italu by its smaller size, more elevated spire, the greater expansion 
of the last whorl, and narrower umbilicus. It also differs in the greater 
solidity of the shell, the much thicker apertural rib, and the usually rich 
brown peristome. 
From YX. virgata it is readily separated by its much more expanded 
umbilicus and its usually more depressed shape.
