THE NATURALISTS’ JOURNAL. 
Dublin Natural History Society. 
Variation. Mr Cockerell, in the British Naturalist’s Catalogue 
of L. & F. Moll: gives five varieties, but they are not recorded in 
Collinge’s recent Catalogue of the Slugs. 
Family TestacellidcB. 
Genus. Testacella , Cuvier. 
Testacella halio tided, Cuvier. 
Distribution. The census records it for eight counties, with no 
records for Wales and Scotland. Variation. The var. scutulum, 
is now acknowledged to be a distinct species. 
Testacella scutulum , Swby. Until quite recently, was consid¬ 
ered to be a variety of T. haliotidea , but was rightly re-instated as 
a valid species, when Mr. Charles Ashford re-investigated the 
anatomy. 
Distribution. The census gives thirteen counties ; no records 
for Wales or Ireland. 
Variation. Collinge acknowledges Cockerell’s var. pallida, and 
excludes his vars. typica and aura. 
Testacella maugei, Fer. 
Distribution. The census gives nine counties ; no records for 
the north of England and Scotland. I have seen examples taken 
from a nursery garden at Castle Cary, Somerset. One variety 
occurs, viz. viridans, Morelet. 
Family Limacidoe. 
Sub-family, Limacince. 
Genus. Limax, L. 
Sub-genus. Heynemannia , Malm. 
Limax maximus, L. 
=Limax cinereus, Mull. 
Distribution. The census records it for seventy counties. An 
addition is Co. six, N. Somerset. It occurs frequently at Bratton 
St. Maur, with the vars. maculatus, Jasciatus, and cellarius; and 
with t! former variety at Doddington, Kent, and Southampton. 
Variati 1. Seventeei vars. are mentioned in Collinge’s catalogue, 
but ciiu ms, Moq., is loubtful. The var. lilacina , Rbk. is a sub- 
variety of krynickii , Kil. 1851. 
The variety cinero-niger, is regarded by the Conchological 
Society, and Mr. Cockerell, as a distinct species ; indeed, Mr. 
Roebuck has gone so far as to say there are important anatomical 
differences. Both Simroth and Scharff regard it as a variety, and 
quite recently Collinge has made a minute examination of the 
anatomy, and fully agrees with these authors. 
Limax tenellus, Nilsson. 
Given as doubtful in Collinge’s Catalogue of British Slugs, and 
in the Conchological Societys’ List. Gwyn Jeffreys, in his 
British Conchology , says :—“a single specimen was found by Mr. 
Blacklock in a wood at Allansford, near Shortly Bridge, in North¬ 
umberland.” Its claim for recognition as a British species being
