Handbook of Manchester. — Prepared by the Local 

 Committee for the members of the British Association, at the 

 Manchester Meeting, 1887. — Mollusca, by J. Cosmo Melvill, 

 M.A., F.L.S., F.E.S., &c. 



Mr. Melvill has compiled a very excellent account of the 

 Land and Freshwater Mollusca of the district twelve miles 

 round Manchester, thus including portions of Cheshire and 

 Derbyshire. In all eighty-three species are enumerated, forty- 

 one of which are freshwater and forty-two land shells. Under 

 each species is given precise information as to the localities 

 where they have been found. The most interesting species is 

 undoubtedly Planorbis dilatatus, which has not yet been found 

 out of Lancashire. 



Manual of Conchology, Structural and Systematic, 



with illustrations of the species. Second series : Pulmonata, by 

 Geo. W. Tryon, Junr. Parts i. — x. 



To expedite the completion of this great work, upon which 

 the author has been engaged for some years, the happy idea was 

 carried out of issuing simultaneously with the marine species, a 

 second series embracing the Pulmonata, of which ten parts have 

 appeared up to the present time. Mr. Tryon divides the group 

 in the first instance into Stylommatophora, which broadly speak- 

 ing, embraces the land snails and Basommatophora which con- 

 tains the aquatic species. 



These parts consist of no less than 757 pages of letter-press, 

 in which every species is briefly described and very often its 

 relationship indicated. The plates, 155 in number, are full of 

 well executed figures of every species described. The work, 

 when finished, will be indispensable to the Conchologist.
