W. D. ROEBUCK AND J. W. TAYLOR- 
Lijvin^ea palustris {Milll.). 
Eecorded for Puckeridge in 1883, by Loydell and Howe. 
Limnaea truncatula {Mull.). 
Eecorded in 1836 by D. Cooper under the name of Limneus 
fossarius, as found “ in the Lea Eiver ” by Thomas Eell. 
Ancylus lacustris { L .). 
Eecorded in 1836 by D. Cooper as found by Thomas Eell “in 
the Lea Eiver.” 
Succinea virescens, Morelet. 
In the Annals of Natural History (1878) Dr. Jeffreys remarks : 
“ This is my variety vitrea of 8. putris ... I lately found a 
specimen at St. Albans with 8. putris, but unfortunately I had no 
time to examine the animal further than by noticing that it seemed 
to be of a darker hue than that of 8. putris or 8. elegans. . . .” 
In ‘Trans. Hertfordshire Nat. Hist. Soc.’ (1881), Dr. Jeffreys gives 
the locality as “at St. Albans, on the bank of the river Yer, near 
the Great Northern Eailway Station,” where he says it occurs with 
8. putris and 8. elegans. 
SUCCINEA PUTRIS (Z.) ; S. ELEGANS, RisSO . 
Porbes and Hanley, who reduce the latter form' to a variety 
{gracilis, Aid.) of the former, write of them as follows: “Our 
friend, Mr. Pickering . . . remarks on some specimens of the two 
leading varieties taken in the neighbourhood of Hoddesdon, Herts, 
that putris occurs on the grass in damp meadows ; gracilis , on 
aquatic plants and mud by the sides of streams and ditches; the 
former may occasionally be met with in the same situations as the 
latter, but I have never met with gracilis in those in which putris 
is- usually found, i.e. in damp meadows.” Dr. Jeffreys also found 
8. putris with 8. elegans at St. Albans, as recorded under 8. virescens. 
ZoNITES CELLARIUS {Mil'll.) \ Z. NITIDULUS {Rrap.). 
Pound at Hitchin in the spring of 1873 by Ashford and Tuke, 
accompanied by the next species. 
Zonites alliarius {Miller). 
Hnder the heading of “ Zonites glaber ,” Mr. Ashford wrote in 
1873: “Mr. S. Tuke and myself took several specimens on the 
30th ult., in w~oods near Hitchin, where it is found under long 
damp moss, associated with Z. alliarius, Z. nitidulus, and Z. 
cellarius. The shells taken are much darker than specimens I have 
received from Cheshire, being of a reddish-brown colour, and ex¬ 
tremely glossy.” The specimens thus placed on record were named 
Z. glaber by Dr. Jeffreys, to whom one or two were sent by Mr. 
Ashford. One of Mr. Ashford’s specimens was afterwards sub¬ 
mitted by Mr. Ponsonby to the judgment of Dr. 0. Eoettger of 
Frankfurt-am-Main, who pronounced it to be “ decidedly Z. allia¬ 
rius .” In this determination Mr. Taylor (to whom the specimen 
seen by Dr. Boettger was afterwards sent and in whose possession 
it now is) concurs.* 
* Dr. Jeffreys assures me that the specimens which lie received from Mr. 
Ashford undoubtedly belonged to Z . glaber. —Ed.
