294 TAYLOR : VARIATION OF LIMN/KA PERliGRA. 



The specimen figured, kindly given nie by Mr. J. Pickering, 

 was named for me by Dr. Jeffreys twenty-five years ago. 



Tlie original figure was given by Montagu, in 1803, on 

 pi. xvi. of his Testacea Britannica. 



Var. inflata Kobelt. Shell large, spire small, whorls not very convex, 

 aperture somewhat pyriform. 



This fine variety is allied to variety 

 ovata, but the body-whorl is more ample 

 and the spire less pronounced. 



I am indebted to the kindness of Mr. 

 H. W. Kew, of IvOndon, for the specimen 

 figured, which he found in the Moat, at 

 Finchley, Middlesex. 



The original figure by Kobelt is in Mai. Bl., 1S70, plate 

 iv., fieure 12. 



Var. patula Da Costa. Shell larger and much more inflated and globular 

 than typicg.1 form, spire short, whorls very con- 

 vex, mouth ample. 



I am disposed to consider the present 

 form as DaCosta's Turbo patnlus, and also 

 as the LiiiincEus aiiipuUacens of Rossm. ; 

 Clessin states that Z. viicrocephalus Kuster, 

 L. JiemisphccricHS Kuster, L. bulla Hartmann, 

 and L. acronicus Studer, are referable to this 

 form, but I have figured the latter in this paper under a separate 

 heading. 



It is probable that the varieties suhovata Locard, snbrotunda 

 Borch., and doliolum Kuster, should also be placed here. 



M. Bourguignat considers that iiikrocephalus Kuster and 

 hemisphcericus Kuster, which I have placed under this head on 

 the authority of Clessin and others, have more affinity with 

 Z. auricularia, and has placed them in his group Auriculariana.
