tAYLOR : VARIATION OF LlMN/EA PEREGRA. 297 



Var. maritima Jeffreys. "Shell dwarfed, rather solid, spire produced, 

 suture deep. L. 0-4, B. 0-225." — Brit. Conch., vol. i.. 

 p. 105, 1S62. 



This is another of the interesting forms of which 

 no authentic figure has as yet been published. The 

 specimen figured answers more exactly to the char- 

 acters given above than any that I have yet seen. It was found 

 along with others of the same variety in "an isolated pond, 

 sometimes nearly dry, at east end of Luffness Links, Had- 

 dingtonshire," by Rev. J. McMurtrie, who kindly gave me 

 some. 



On the continent there seems to be some misconception 

 about the characteristics of this variety, Herr Clessin errone- 

 ously giving it as synonymous with variety balthica L., a 

 globose short-spired form ; Westerlund also gives it as a short- 

 spired variety, though the author of the variety expressly states 

 'spire produced,' and instances the form of L. tnincatula as 

 recalling to some extent that of this variety. 



Var. acuminata Jeffreys. "Shell resembling the last variety [var. ovata 

 Drap.] in all respects, except in having a more pro- 

 duced spire and a smaller mouth." — Brit. Conch., 

 vol. I., p. 105, 1862. 



Dr. Jeffreys characterized this variety in a 

 wholly comparative way, setting out the relation 

 it bore to the variety ovata. I have seen no 

 authentic or reliably-named specimen, though I 

 have made many fruitless efforts to obtain an example identified 

 by Dr. Jeffreys himself. 



This form bears a great resemblance to some of the speci- 

 mens of L. columella Say, as figured by some American authors. 



The Gulnaria percgra var. amtispirata of Clessin seems to 

 be referable to this variety, judging from the figure he gives. 

 His varieties raiblensis and janoviensis would also seem, accord- 

 ing to his most recent figures, to be quite similar, though the
