On the occurrence of Vertigo Moulinsiana Dup. in 

 Herts. — By H. Groves, Trans. Herts. Nat. Hist. Soc, vol. i., 

 part 2, 1880 with plate. 



Mr. Groves, in this paper gives an account of the British 

 distribution of the true V. Moidinsiaiia, Dup., as far as he 

 himself has observed it. The localities he enumerates are near 

 Otterbourne, Hants.; Hitchin, Herts.; and on the Essex border 

 of Herts., near Rye House. 



The habitat of this species is the swampy margins of rivers 

 and ditches and very wet marshes, with such plants as Carex 

 panicidata, C. paludosa, C. riparia, Juncus^ Iris, Typha, Phrag- 

 mites, &c., up the growing leaves and stems of which it occurs 

 in the greatest numbers, while V. aniivertigo, its companion 

 seems to prefer the decaying leaves which have fallen into the 

 water, and is found just above the surface of it. 



Mr. Groves calls attention to the dwarfing of specimens 

 occurring in small isolated localities and points out the probable 

 causes. — J.W.T. 



Mediterranean Mollusca (No. 3) and other Inverte- 

 brata. — By J. Gwyn Jeffreys, LL.D., F.R.S., &c., from Ann. 

 and Mag. Nat. Hist, June, 1883, p. 393 — 401 with plate. 



This paper is another contribution by the eminent con- 



chologist Dr. Jeffreys to our knowledge of the Mediterranean 



mollusca. Admiral Spratt having placed at Dr. Jeffreys disposal 



some material dredged about 30 years ago off Crete, in from 



70 — 120 fms., Mr. and Mrs. Robertson kindly sorted the 



material for Dr. Jeffreys, and supplied the lists of Ostracoda 



and Foraminifera which are app.nded to this report. The total 



number of species enumerated is about 150, of which one is a 



Brachiopod, 38 Conchifera, 4 Solenoconchia, 6 Pteropoda, while 



th^ remainder belong to the Gastropoda. Nine new species 



are described and figured. Cyclostrema minutmn (pi. xvi., fig. i);
