idea which is certainly borne out by its general aspect. When, 

 however, recently working out some material for the Indian 

 Museum, the author had occasion to send specimens of what, after 

 comparison with the type specimen in the British Museum, he 

 believed to be this species to the Rev. E. W. Bowell for dissection, 

 his report states " that the genitalia are very similar to those of 

 the common European form L. auricularia, Linn. The vas deferens 

 is, however, markedly shorter, and the radula is remarkable for 

 the length of the cusps and their subulate appearance, and also 

 for there being no great distinction in type between the laterals 

 and marginals." 



Keeve, in his description, gives no actual dimensions, but those 

 above given are taken from his smaller figure which is said to be 

 of natural size.
