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 Conide, 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 Pélécypodes et de Gastéro- 
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. Amphirissoa, Basilissopsis 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 bas recently described and figured a second 
fine species of Thersites from New Guinea, T. septentrionalis. It is 
more elevated than 7. broadbenti, more like the Queensland T. 
etheridgei (Ree. Austr. Museum, III, No. 1). In conjunction with 
Dr. Arthur Willey, the same author describes a new Astralium of 
the subgenus Guildfordia, from New Britain. It is some 45 mm. 
in diam., and resembles the well-known A. triumphans from Japan. 
Messrs. Melvill and Ponsonby have contributed to the Annals and 
Magazine of Natural History for June, 1897, another article upon 
Land and Fresh Water Mollusca from South Africa. New species 
of Achatina, Ennea, Pupa 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 well developed 
tegmenta upon the valves of young Californian Cryptochiton Stellert. 
There are also small “sutural tufts,’ homologous with those of 
Acanthochites. A good plate illustrates these and other features.
