LIMAX. 161 



FOSSIL SPECIES. 

 Limax modioliformis Sandbergen 



Limax modioliformis Sandbevger, Palaiontographica, 1880, p. 113, pi. xii., f. 1^ 



Shelt. transparent or diaphanous, but thick in substance, 

 somewhat ovoid and bearing a certain resemblance to the rahe 

 of a small Modiola ; apex or nucleus terminal and placed 

 towards the left corner ; upper side, especially in aged speci- 

 mens, more or less strongly wrinkled, with the (•oncentrio lines 

 of growth, between which dark arborescent markings can be 

 detected ; UNDER side rugosely granulate. 



Length, 5 mill. ; breadth, 3 '5 mill. Fig. 180. —Limax 



iftodicH/oniiis Sand- 



This species, which was found in some numbers by berger, enlarged (after 

 Mr. Clement Reid, has, according to >Sandberger, some ^" ""^^ ' 

 affinity in form with the Limax crasdtesta of Reuss, from the Lower 

 Miocene of North Bohemia. Dr. Bottger 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 

 Limax arhorum, which is also found in the same beds.

 Limax kttiis Coekerell, Conch,, Sept. 1893, p. 174. 



Shell broadly sub-conical, somewhat incrassate, and *"' \ 



greatly depressed, with the vertex or nucleus about half-way /^Sm.- ''~i- 



between the margin and the middle. \t'-^i '.^ 



Length, about 64 mill. ; breadth, about 5 mill. \:i^,-^y 



This species, of which only an imperfect specimen p_^_ isi.-Lmajc 

 was known to Mr. Edwards, was characterized by him, /ai'KiCEdw.), enlarged 

 though with considerable doubt and hesitation, as an *''^'" Edwards). 

 Ancylus\ it, however, proves to be, according to Woodward's Manual,' 

 really the shell of a Limax. 



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. 

 Olig-ccene— 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 Wight, and at Hordwell in South Hants.
