296 lAYLOR : VARIATION OF LIMN.EA PEREfiRA. 



Var. oblonga Jeffreys. "Shell oblung and compressed in front." Brit. 

 Conch., vol. I., p. 105, 1S62. 



This is one of the varieties of which I am 

 unaware of any published figure and which we 

 are compelled to identify by a careful study of 

 the description. 



The figure given by Clessin in Die Moll.- 

 Fauna Oesterreich-Ungarns und der Schweiz of var. conipressa 

 Hartmann, may, in my opinion, be placed here, if we do not 

 wish to exercise too great a degree of refinement in the differen- 

 tiation. 



The specimen figured was collected in May, 1883, from a 

 ditch near Finningley, South Yorkshire. 



SECTION B. 

 Spire proJiiced, aperture not exceeding three-foitrtlis of the total length 

 of the shell. 



Var. microstoma Kobelt. Shell more elongate and slender than type, with 

 a spire perceptibly longer than the mouth, the 

 whole shell approximating in general outline to 

 L. paliistris. 



To this, the longest-spired variety of this 

 species, I have Clessin's authority for referring 

 as synonymous the vars. eloiigatissinia Gredler, 

 alpicola \\c^ie.x\\xndi,paliidaruiii llixxlminn, producta ^Vesterlund, 

 and his own variety clo/igata. The figures he gives do not, 

 however, satisfactorily confirm the views he expresses. 



According to Westerlund the variety aprice/isis of G. B. 

 Adami, which has been renamed L. apricatia by M. Bourguignat, 

 is entirely the same as variety microstoma Kobelt. 



The specimen figured, which agrees fairly well with 

 the original one given by Kobelt at fig. 1491 of his continua- 

 tion of Rossmassler's Iconographie, was found by Mr. B. 

 Hudson at Seaton Carew, and kindly given to me by him.
