described by Locard and Kobelt, and suggests that minima would 
be an appropriate varietal name, if other adult forms have been 
or should be found of the same size. The full normal size of L. 
stagnalis is about 54 mill. in length, and 28—80 mill. in breadth. 
L. truncatula, Mull., var. elegans.—In a small rill at Carlton, 
near Pontefract. 
L. truncatula var. minor.—Methley, three or four specimens. 
TERRESTRIAL MOLLUSCA. 
GASTROPODA. 
Fam. Limacipz. 
Arion hortensis, Fer., var. grisea.—Ledstone and Went Wood. 
_ A. hortensis var. — In a bed of nettles near Pontefract, on 
limestone, I found specimens of A. hortensis which appeared 
very different from our ordinary sandstone varieties. There 
were two forms, the descriptions of which from my note-book 
made at the time are as follows :—(1) Body broad, of a primrose- 
yellow colour; the colour strongest on the fore part of the shield 
and the tail; no lateral stripes; tentacles brown; respiratory 
orifice minute. (2) Body narrow, orange-brown ; lateral stripes 
dark ; a narrow dark brown border round the shield; tentacles 
bluish black. This variety, when confined in a box, fed on 
another dead Arion, though it was surrounded by vegetable 
matter of various kinds. 
Limax maximus, Linn., var. cellarius.—A common form. 
L. agrestis, Linn., var. sylvaticus.—Very common form. 
Fam. Heticip#. 
Succinia pfeiffert var. minor, Rossm.— Pond close to the rail- 
way, about a quarter of a mile east of Milford Junction. 
S. elegans var. minor, Jeff.—With the above. 
Helix aculeata, Mull.— Went Wood, June, 1886. 
H. nemoralis var. albinus. — Shell white, 00000 and 12845. 
Milford. 
Var. albolabiata + citrinozonata.—Pontefract. 
Var. petiveria, Moq.—Pontefract, frequent. 
Var. olivacea, Goss.— One specimen, bright olive-brown, with 
one brown band, and one white band beneath. Most specimens 
of this variety are bandless. 
Var. rubella, Moq.— New formula, 00345. Pontefract.
