THE NAUTILUS. 



Ill 



Recent Acquisitions. 



Since the publication of our new Catalogue of Mollusca, an- 

 nounced in the July issue, we have acquired a series of 



Rare and Beautiful Shells, 



many of which are not in the regular catalogues. They have been 

 culled from the well-known collection of a deceased French Con- 

 chologist, and include some unique shells. Among them, we call 



attention to Strombus go lint h (a magnifi- 

 cent specimen), Strombus thersites, Murex 

 trifariospinosa, Triton tigrinus, Bucci- 

 nopsis canaliculatiis, Dall, Northia serrata, 

 Valuta junonia, V.kingi, V- mamilla, etc., 

 Mitra terebralis, Harpa crenata, Conus 

 fiorldanns, Halia priamus, Cerithium Iceve, 

 Turbo splendid ulus with authentic local- 

 ity, etc. 



The collection is especially strong in 

 the families; Muricidcc, Ollvidce, Conidce, 

 Strom bidce, Cypneidce Turbinidce and 

 Trochidtc, Fissurellidce, Patellidie, and 

 the Chitons; and among bivalves there 

 are fine series of Tellina, Venus, Cytherea, Pecten, Spondylus, and 

 Brachiopoda. 



Price lists of species not in our regular slock will be sent to 

 collectors upon application, but, since many of the more desi rattle 

 species are represented by single specimens only, specialists desiring 

 to fill out their suites would do well to write to us at once naming 

 their chief desiderata. 



The demand for the new CATALOGUE OF MOLLUSCA ( 170 pages, 200 illu- 

 strations ) shows that it has met the approval of the public. It is 

 sent to any address for 10 cents, post-paid.
