larger (from north to south) than broad. Var. articulaiir, i.e., 

 jointed, was so named by Lamarck, who probably meant to indicate 

 that it has alternate transverse ribs of white and violet-brown. 



The genus T/ieba Leach in his synopsis prints " Teba." It is 

 suggested that it is named after Thebes; but then it would be Thebse 

 or Thebe. It has two representatives, cantiana, which dtrives its 

 name from having been first noticed in Kent. Var. gallop rovinciali<, 

 i.e., found in the Gallic province, later called Provence. Var. 

 albocincta, i.e., girdled with white, from the reddish colour being 

 absent on the periphery. Cartusiana, i.e., found near a Carthusian 

 monastery. Var. ladescens, i.e., becoming milky in colour ; var. 

 leucoloina means bordered with white, i.e., having a white peristome 

 or rib ; var. rufilabris^ i.e., with red lips. 



The genus Hygromia (i.e., frequenting damp places) has the section 

 Fruficicola, orchard inhabiting, with the species fusca, i.e., dusky 

 brown ; graniilata, i.e., minutely granulated, Uke shagreen where the 

 hairs have worn off (named by Jeffreys sericea, i.e., silky, in allusion 

 to the soft hairs it bears) ; hispida, i.e., hairy (the same as Jeffreys' 

 co^icintia, i.e., neat). Var. depilata denoted that no hairs are found. 

 Dr. Gray in Turton calls it the " bald snail." Var. nana is a dwarf, or 

 smaller than the type. 



(To be concluded). 



BIBLIOGRAPHY. 



(limited to WORKS RECKIVED HY THE SOCIETY'S LIBRARIAN). 



Monograph of the Land and Freshwater Mollusca of the British Isles, 



part 19 (pp. 369-416, and 4 plates), by JOHN W. Taylor (Taylor Bros., Leeds). 



Every part of Mr. Taylor's work is eagerly welcomed, and none more than those 

 dealing with the HelUida. Part 19 furnishes us with complete monographs of 

 Helix pisana Miill. and Helicigona lapicida L. Of the four plates, No. 15 takes us 

 back to the Zonitidce, and is Mr. Taylor's own attempt to give reliable figures of 

 Hyalinia, Zonitoides and Eticoniiliis. We congratulate him on a very successful 

 and artistic result. Another plate gives us the Distributional Map of H. pisana. 

 We are a little surprised to see co. Kerry coloured in this map, when the 

 authenticity of the record seems so doubtful. May it not be explicable on the 

 same hypothesis as the West Galway record ? All collectors will welcome the 

 two very beautiful coloured plates on which are figured the type and thirty-seven 

 named varieties of //. pisana. Altogether, this part is an excellent piece of work.
