Robert, A. — Sur la ponte des Troques. Compt. Rendus, 1901, vo'. cxxxii., 

 pp. 850, 851. 



The author draws attention to the interesting fact that whereas in certain 

 species of Trocliits [T. i^ranidatiis. Born., T. striatiis, L., T. coiiidoidcs, Lam., and 

 T. cxaspcratiis, Penn.) the eggs are deposited in agglomerated masses, the] 

 matrix being a mucous secreted by an ampulla-like swelling on the excretory 

 duct of the right kidney, in the females ; in other species (T. magus, L., 

 T. ciiiciriis, L., and T. cnissiis, Pult.) the eggs are deposited singly. 



Hedley. C. — studies on Australian Alollusca. Part iv. Proc. Linn. Soc. 

 N.S.W., 1901, pp. 16 — 25, pi. ii. 



The following new species are described and figured : Liotia vcniiata, L. 

 dcvc.xa, Tciiiostoina vesta, and Lima bnnnica. Illustrations of some hitherto 

 unfigured species are also given. Discussing the "Challenger" Station 164B, 

 Mr. Hedley thinks that possibly " 164B " might be a mistaken label for "64," 

 in anv case it seems to us that he is perfectly justified in eliminating the series 

 from the Australian fauna. 



Hedley, Charles. — A Revision of- the Types of the marine shells of the 

 "Chevert" Expedition, Rec. Aust. Mus., 1901, vol. iv., pp. 121 — 130, 

 pis. xvi — xvii. 



Mr. Hedley points out that sirice the collection made by the Staff of the 

 " Chevert," and now in the Macleay Museum, Sydney, was described, later 

 writers have failed to identify the species, and have complained of the 

 inadequate descriptions. He now amplifies these descriptions by giving 

 dimensions and figures, and corrects the synonymy. 



Hedley, Charles. — The Marine Wood-borers of Australasia and their work. 

 Anstr. Assoc. Adv. Sci., 1901, vol. viii., pp. 237 — 255, pis. vii — x. 



The author gives an interesting account of what are popularly termed 

 ship-worms, designed rather for the engineer and general student than the 

 zoologist. 



Knight, G. A. Frank. — Manne Mollusca and Brachiopoda. Brit. Assocn. 

 Handbk. on the N.H. of Glasgow, 1901, pp. 189—208. 

 The author records no less than 393 species of molluscs, of these 23 are 

 doubtful or insufficiently attested. A biblography containing 43 titles prefaces 

 the li>t, and useful notes are appended to the various species. To all interested 

 in the distribution of the Marine Mollusca of the West of Scotland this valuable, 

 but unpretentious publication, will prove of great service.
