Mr, J. W. Taylor, in his valuable paper on Limncea peregra, 

 has ( 'Journ. of Conch.', 1891, p. 298) referred my var. ovali- 

 formis to var. vulgaris C. Pfr. I think, 

 however, it is a quite distinct form, since 

 it differs from vulgaris in its greater size,

 Taylor's paper, and, as it has never yet been figured, I give a 

 drawing of it, traced from a sketch of the original specimen I 

 made several years ago.

In reply to Mr. T. D. A. Cockerell's kindly expressed criticism,

 me, which are careful and accurate re-

 in 1886 of the type shell which Mr. 

 Cockerell had most kindly sent to 

 Leeds for examination. The differ- '"'""""TySe slieu.*^™"''^ °^ 

 ences exhibited in my exact copies of photographs and Mr. 

 Cockerell's sketches of the identically same shell are perplex- 

 ing, but a possible explanation may be that he did not antici- 

 pate controversy and did not sketch the outlines as accurately 

 as he otherwise might have done, or he may unintentionally
