Novitates Conchologlcae. Supplement III. Nos. 12 and 13. (Mono- 

 graph of Venus, L., with six colored plates.) 



The present issue is occupied by an account of the species 

 of Dione, by Dr. Edward Romer.

 tinued by H. C. KiiSTBK. 187th Part. 4to. 6 colored plates. NUrnberg. 

 1868. 



This work is also now occupied with the Veneridae. 



Monographia Heliceorum viventium. By Dr. Louis Pfeiffer. Vol. V. 

 (Third Supplement. Vol. 1.) 565 pp. Sto. Leipzig. 1868. 



This volume gives the additional species and synonymy that 

 have accumulated since the date of the 4th volume, 1859. The 

 same style of treating the subject and the same artificial classi- 

 fication is continued, as in the previous monographs. The pre- 

 sent publication contains the species principally of Helix, of 

 which the numbers amount to 2833 species, being an increase 

 of 735 species since 1859, notwithstanding since-discovered 

 synonyms. 



It would be a work of supererogation to write a laudatory 

 notice of such a work as PfeiiFer's. Its best recommendation is 

 that no Conchologist can undertake to study terrestrial shells 

 without it. 



Nachrichtsblatt der deutschen Malakozoologischen Gesellschaft. 



Nos. 1 and 2. Dec, 1868. No. 3. Jan., 1869. 



This is a 16-page sheet, issued by a new association intended 

 to encourage and advance the interests of Malacology among 

 the Germans and others. It is a vehicle of communication and 

 a receptacle for stray facts and opinions. It is a sort of Con- 

 chological "Notes and Queries," — and as such will doubtless 

 become of value. There is as yet no attempt to describe new 

 species or genera, and we do not know whether or not such 

 papers are contemplated as a feature of the Magazine.
