etc. It is hoped that nothing will hinder the timely comple- 

 tion of this important work. 



Another thorough anatomical paper, "Beitrage zur Kenntniss der 

 Coniden," by Dr. R. Bergh, has appeared (Nova Acta der K. 

 Leop.-Carol. Deutchen Akad. der Naturforscher, LXV, No. 2). It 

 is a well illustrated work on the soft anatomy of one of the most 

 prominent families of marine Gastropods, the Conidce, which, like 

 many other groups, has long been well known conchologically, but 

 only slightly anatomically. C. Pealii is the only United States 

 species investigated. 



In their " Diagnoses d'Esp. Nouv. de Pelecypodes et de Gastero- 

 podes " (Bull. Soc. Zool. France, 1897), by Ph. Dautzenberg and H. 

 Fischer, a good many species from the eastern Atlantic dredged by 

 the "Hirondelle" and " Princesse Alice," are described but not 

 figured 1 .! Amphirissoa, Basifissopsis and Aliceia are new genera. 

 Species of Turcicula, Cocculina, Cetoconcha and other interesting 

 genera are included. Mons. H. Fischer seems to be following in 

 the footsteps of his distinguished father. In M. Dautzenberg he has 

 an experienced and able collaborator. 



Mr. Charles Hedley has recently described and figured a second 

 fine species of Thersites from New Guinea, T. septentrionalis. It is 

 more elevated than T. broadbenti, more like the Queensland T. 

 etheridgei (Rec. Austr. Museum, III, No. 1). In conjunction with 

 Dr. Arthur Willey, the same author describes a new Astrafium of 

 the subgenus Guildfordia, from New Britain. It is some 45 mm. 

 in diarn., and resembles the well-known A. triumphant from Japan. 



Messrs. Melvill and Ponsonby have contributed to the Annals and 

 Magazine of Natural History for June, 1897, another article upon 

 Laud and Fresh Water Mollusca from South Africa. New species 

 of Achatina, Ennea, Papa and other genera are described, and also 

 a species of Hapalus, a Bulimoid group not hitherto found so far 

 south. 



An interesting paper by Mr. Harold Heath (Proc. Acad. Nat. 

 Sci. Phila.) demonstrates the possession of small but Avell developed 

 tegmenta upon the valves of young Californian Oryptochiton Stelleri. 

 There are also small "sutural tufts," homologous with those of 

 Acanthocliites. A good plate illustrates these and other features.
