Bouchard-Chantereauxf says that it deposits from twelve to 

 fifteen comparatively large eggs, which are whitish and globular 

 and about ij^ mill, in diameter. Deposited at the beginning of 

 autumn, they hatch on the fifteen to the twentieth day, and the 

 young arrive at maturity at the end of the first year. These 

 observations have been reproduced by Moquin-Tandon and 

 Jeffreys. 



I fail to discover any way of reconciling these two con- 

 tradictory accounts. Both are equally explicit and, doubtless, 

 conscientiously given. There can be no questioning the 

 accuracy of Mr, Craven's statements, as I have before me a 

 series of adult specimens and of the minute shells taken from 

 the apertures of the old ones, which he has presented to the 

 British Museum. 



I am inclined to believe that Bouchard-Chautereaux was 

 in some way mistaken ; for it seems too wild a theory to sup- 

 pose, either, that after hatching the young may re-enter the 

 parent shell, or that this mollusc has more than one mode of 

 reproduction. — Edgar A. Smith.

Helix lapicidav. subangulata Pascal. — This interesting 

 variety, described by Pascal as similar to the type in colouring, 

 but differing from it in the last whorl being rounded and not 

 carinated as usual in the species, has been found in Dovedale 

 by Mr. C. T. Musson, who kindly gave me the specimen I now 

 possess. It has a very great resemblance in general contour 

 and size to the Helix cornea, and would appear to be the same 

 form as var. grossularice Voith. It has apparently been also 

 noticed by Weinland, who records it as variety without keel. 

 Perhaps more specimens may be found now that attention is 

 drawn to its discovery in this country. — J. W. Taylor, April 

 2Sth, i8gi.
