Dr. Simroth is of opinion that the genus Ostracolethe, described by 

 liini in 1901, is the same as Myotesta, Cllge., described in the same year. 

 Tbere are, liowevcr, quite a number of differences in the two accounts. 

 Dr. Simroth states tliat tlie mantle is perforated, and that tliough the cleft 

 there projects tlie fine point of a conch-like sliell, while Mr. Collinge 

 very cmpliatically states that tlie shell is flat and plate-like, and entirely 

 covered and enclosed by tlie mantle. The radula is also a further point 

 upon wliich the two autliors are at variance.

 Dautzenberg, Ph. — Bevision dcs Cypraeidae de la Xouvelle-Caledonie. 



Journ. de Conchyl., 1902, vol. 1, pp. 291-384, pi. vii. 

 Tlie Cypraeidae of Xcw Caledonia have previously been catalogued by 

 Crosse in 1869, wlio enumerated 45 species, also by Bossiter in 1882, whose 

 list contained 60 species. The present Bevision treats of 70 species, and 52 

 ^arieties, 12 of wliich arc new, in addition to wbicli 7 monstrosities are 

 described and figured. 



Not wishing liere to enter into a discussion of the value of the different 

 divisions of the family, the author adopts four principal genera : Cypraea 

 (s.s.) Liiponia, Epona and Trivia.
