SOWEEBY : NEW SHELLS FROM HONG-KONG. 157 



haud angulatus ; apertiira oblongo-ovata ; columella callosa, leviter 

 inflexa; labrum arcuatum. Long. 31, diam. maj. 6 mm. 

 The shell is of a peculiarly narrow elongated form. 



Family PYRAMIDELLID^. 



14. TURBONILLA. SINENSIS, U.Sp. PI. XII. Fig. 9. 



Testa elongato-turrita, sordide albida ; spira obtusiuscula ; anfractus 

 8-9, costis numerosis rotundatis angustis, interstitiis spiraliter pro- 

 funde multisulcatis scalpti ; sutura impressa ; anfractus ultimus 

 oblongus, leviter inflatus, haud angulatus ; apertura ovata ; columella 

 leviter incurvata, minutissime uniplicata. Long. 4-50, diam. 1-30 mm. 



In sculpture this species is very like the British T. rufa, Phil., from 

 which it differs in form, the body-whorl being larger and the spire 

 less acute. 



15. TUKBONILLA TENTJISTEIATA, n.Sp. PI. XII. Fig. 10. 



Testa elongata, sordide albida, tenuis ; spira turrita, ad apicem 

 mucronata ; anfractus 8, planati vix convexi, superne obtuse angulati, 

 sutura impressa sejuncti, longitudinaliter striati, striis tenuibus eon- 

 fcrtis, leviter undulatis ; anfractus ultimus breviusculus ; apertura 

 oblongo-ovata ; columella tenuis, levissime reflexa, plica unica obliqua 

 minutissima instructa. Long. 10, diam. 2*50 mm. 



Unlike most of the species of Turhonilla this shell has no prominent 

 longitudinal ribs, but only fine striae. It is of rather fragile sub- 

 stance, has a slight angle at the top of the whorls, and a well-defined 

 suture. 



16. ClNGITLINA TEISTJLCATA, H.Sp. PI. XII. Fig. 6, 



Testa elongata, angusta, polita, alba ; spira per-elongata, acuminata ; 

 anfractus 14, planulati, spiraliter trisulcati ; sutura canaliculata ; 

 anfractus ultimus breviculus, vix convexus, ad basin rotundatus ; 

 apertura sub- ovata, latiuscula ; columella tenuis, fere recta, haud 

 plicata ; labrum tenue, arcuatum. Long. 11, diam. 2 mm. 



The true generic position of this shell may be regarded as doubtful. 

 It differs from the typical species of Cingulina in having a smooth 

 polished surface, and spiral grooves instead of ridges. It, however, 

 so closely resembles Cingulina spina (Crosse and Fischer) in general 

 fonn, and in the character of the columella, that I have little doubt 

 that I have placed it correctly. 



17. Odostomia subcaeinata, n.sp. PI. XII. Fig. 11. 



Testa conico-acuminata, alba, solidula, glabra ; spira acute conica ; 

 anfractus 7, Iseves, vix convexi ; sutura canaliculata ; anfractus 

 ultimus spiram subsequans ad peripheriam carinatus, angulatus, 

 infra angulum convexiusculus, anguste umbilicatus ; apertura ovata, 

 intus lirata ; columella leviter incurva, plica acuta leviter obliqua 

 instructa. Long. 5-30, diam. 2-50 mm. 



A robust, conical, white Odostomia, with a threadlike keel at the 

 periphery. It is one of the largest species of the genus, somewhat 

 resembling the European 0. conoidea, Brocchi, 



18. Etjlimella tenuis, n.sp. PI. XII. Fig. 8. 



Testa elongata, angusta, albida, pellucida, tenuis; spira per-elongata,
