190 Mr. E. A. Smith on new Species of Helicidae. 



Cyclostoma elegans, Mull. Dead and empty, but with the opercu- 



- lum still closing the aperture. 



This last, together vrith. Helix concinna, Melampus myosotis and 

 its variety, and Truncatella, I have found on the shore only, mixed 

 with more common land-shells, a few days after a very high 

 spring-tide. They were all full of air, very buoyant, and were 

 left on the sand by the receding tide at its upper limit. May 

 they not have been wafted over from the opposite coast of France 



. by the strong tides and currents ? 



XXVII. — Descriptions of four new Species of Helicidce. 



By Edgar A. Smith. 



The British Museum has recently purchased a small series 

 of shells, said to have been collected at D'Entrecasteaux 

 Island, off the south-east of 'New Guinea. Besides the new 

 species about to be described, it includes examples of Hi 

 Tayloriana, Adams & Reeve, = H. yulensis. Brazier, Helix 

 Broadbenti, Brazier, and a very beautiful variety of H. cor- 

 niculnm, Hombron & Jacquinot. It is rather larger than 

 Reeve's figure (Conch. Icon. f. 502), and has the black band 

 twice as broad, and the lip much more expanded and of a pretty 

 rose-colour. 



Helix (Geotrochus) Tapparonei. 



Testa imperforata, trochiforniis, lactea, labrum versus lutescens, 

 super ne zonis tribus vel quatuor inaequalibus nubilo-rosaceis 

 (una prope suturam interrupta) ornata, undique minute, oblique 

 corrugata. Anfractus quinque, levissime convexi, celeriter accre- 

 scentes, sutura lineari sejuncti ; spira concaviuscula, apice ele- 

 vato, subobtuso, nigro ; anfr. tertius et quartus infra suturam 

 lactei, inferne roseo suffusi ; ultimus in medio acute angulatus, 

 inferne paulo convexus, prope labrum subito valde descendens ; 

 apertura valde obliqua. Peristoma saturate nigrum, contractum, 

 margine dextro insigniter bisinuato, aliquanto infra medium 

 columellam versus acute producto, vix expanso ; margo columel- 

 laris latus, reflexus, vix planus sed leviter excavatus, in medio 

 marginis tuberculis duobus parvis munitus, superne callo nigro 

 longe intrante labro junctus,

I do not know any species sufficiently approaching that now 



described with which a comparison can be made. Helix 



Macgillivrayi has a somewhat similar indentation of the outer
