434 D)\ H. Woodicard — Recent and Fossil Pleurotomarice. 



tomarice from the fauna of to-day has been also reduced by the 

 discovery of seven Eocene, two Miocene, and two Pleistocene species ; 

 whilst the dredge of the zoologist and the nets of the fishermen 

 have demonstrated with equal success that Pleurotomaria is living in 

 the seas of the present time. 



The following is a list of the Tertiary species of Pleurotomaria : — 



(Eocene) Fleurotomaria Bimiconii, d'Archiac, India. 



concava, Deshayes, Paris Basin. 



Duboisii, Mayer, the Crimea. 



■ Genyi, Mayer, Nice. 



KacUn-Kewiensis, A' KxchiSiC, Asia Minor. 



Lamarckii, Mayer, Switzerland. 



Nicmensis, Bayan, Nice. 



(Miocene) Sisnioridi, Goldfuss, Biinde. 



tertiaria, M'Coy, Australia. 



(Pleistocene) Fischeri, Mayer MS., Guadaloupe ? 



Duchassaingii, Schramm, Guadaloupe ? 



The rarity of living Pleiirotomarm, whether in public Museums 

 or in private Collections, is an incontestable fact. Neither the 

 British Museum (Natural History), nor the Museum of the Jardin 

 des Plantes, Paris, possesses an example. 



Mr. W. H. Dall, in his Preliminary Eeport on the Mollusca dredged 

 in the Gulf of Mexico, etc., 1877-78, by the U.S. Coast Survey 

 Steamer " Blake," ' in 1881, records the existence of eight individuals 

 onlj, that were actually known to him to exist in collections ; whilst 

 M. H. Crosse (Journal de Conchyliologie, 1882, p. 20), a year later, 

 mentions ten specimens of living species obtained up to that date : — 

 viz. : — 1 Pleurotomaria BumpJdi (in the collection of the Jardin 

 Zoologique, Eotterdam) ; 5 of P. Adansoniana (viz. 1 in the 

 collection of M. H. Crosse (the type), 1 in the Museum of M. Lher- 

 minier, 3 in the Museum of Zoology and Comparative Anatomy, 

 Cambridge, Mass.) ; 3 of P. Quoyana (viz. 1 in the collection of 

 Miss De Burgh (the type), 2 in the Museum Zool. and Comp. Anat., 

 Cambridge, Mass.) ; 1 P. BeijricMi (collection of Dr. Hilgendorf), 

 We may now add a second specimen of P. Beyrichii, in the collection 

 of Mr. R. Damon, F.G.S., of Weymouth (see Plate XL Fig. 1). 

 This specimen, obtained by Dr. C. Grottsche, of Berlin, during his 

 residence in Jaj)an, from a fisherman of Enoshima, was actually 

 caught with the mollusc in it, but the intelligent native very carefully 

 removed it, and thus a most valuable prize was lost to science. 

 Dr. Gottsche obtained the shell from the fisherman two hours after 

 it had been taken alive, and from the good state of its preservation, 

 and its brilliant coloration, there is every reason to believe that 

 it was an actual living example when found. 



It contrasts most favourably both in coloration and condition with 

 Dr. Hilgendorf 's specimen of P. Beyrichii (as figured by von Martens 

 in the Conchological Mittheilungen, Cassel, vol. i. pi. vii. 1880), 

 which does not display the slit, and is in an extremely poor state of
