the same species, but usuaUy within certain limits ; its surface, as to the marking, 

 appears to us to be almost the same in every British species, being minutely and 

 closely dotted with impressed points, at length, when ripe, almost quite smooth, 

 and never rough with raised points or papillae. Some valuable remarks on some 

 ot the species and their arrangement, have been made by Mr. John M'Laren in 

 the Botanical Gazette, vol. iii. p. 17.
