LIMAX. 161 
FOSSIL SPECTES. 
Limax modioliformis Sandberger. 
Limax modioliformis Sandberger, Paleeontographica, 1880, p. 113, pl. xii, f. 15. 
SHELL transparent or diaphanous, but thick in substance, 
somewhat ovoid and bearing a certain resemblance to the valve 
of a small Modiola ; APEX or nucleus terminal and_ placed 
towards the left corner ; UPPER SIDE, especially in aged speci- 
mens, more or less stronely wrinkled, "with the concentric lines 
of erowth, between which dark arborescent markings ean be 
detected ; UNDER SIDE rugosely granulate. 
Length, 5 mill. ; breadth, 3°5 mill. Fic. 180. — Limax 
modioliformis  Sand- 
This species, which was found in some numbers by _ berger, enlarged (after 
Mr. Clement Reid, has, according to Sandberger, some ae 
affinity in form with the Limaa crassitesta of Reuss, from the Lower 
Miocene of North Bohemia. Dr. Béttger and Mr. Heynemann are quite in 
accord in being unable to identify this shell with that of any recent species, 
although Bronn has suggested a similarity in structure to the shell of 
Limazx arborum, which is also found in the same beds.

Limax latus (Edwards). 
Ancylus? latus F. E. Edwards, Monog. Eoc. Moll., 1852, p. 110, pl. xiv., f. 15. 
Limax Jatus Cockerell, Conch., Sept. 1893, p. 174. 
SHELL broadly sub-conical, somewhat incrassate, and ai 
greatly depressed, with the vertex or nucleus about half-way cs 
between the margin and the middle. 
Length, about 64 mill. ; breadth, about 5 mill. 
This species, of which only an imperfect specimen alae Oem oP 
was known to Mr. Edwards, was characterized by him, — Zatus (Edw.), enlarged 
though with considerable doubt and hesitation, as an (“fer Edwards). 
Ancylus; it, however, proves to be, according to Woodward’s Manual,’ 
really the shell of a Lina. 
Mr. Edwards described the shell as distorted at the posterior extremity, 
and as presenting the appearance of a sinus, somewhat resembling, though 
in an exaggerated form, that presented by the shells of the Limacina. 
This sinus, or indentation, he believed was probably due to the accident 
which produced the distortion. 
BRITISH ISLES. 
Oligocene— Recorded for Sconce, near Bembridge, in the Isle of Wight, by 
Edwards, and according to Mr. Ashford, has also been found in the Headon Beds 
at Headon Hill, in the ‘Isle of W ight, and at Hordwell in South Hants.
