3. Description of a New Species of Pandora. 

 By Sylvanus Hanley. 



Pandora cumingii. Testa magna, semilunaris, maxime incequi- 

 lateralis, concentrice obsolete undata. Latus anticum per- 

 breve, haud{ut in P. ceylanica) latus posticum valde productum 

 et sensim rostratum in latitudine superans. Rostrum acclive, 

 ad apicem satis {vix tamen in adultis) angustum, obtuse sub- 

 biangulatum. Margo dorsalis anticus subito declivis ; posticus 

 notabiliter incurvatus ; ventralis perarciiatus et utrinque cequa- 

 liter acclivis. Area dorsalis lata, complanata. Nates acutcs, 

 conspicue elevatce. Cardinis denies haud longi. 

 Long. 1^ poll., lat. f poll. 



Hab. Samar et Negros, Insulas Philippinas (Cuming.), in luto 

 arenoso. 



This falchion-shaped Pandora exhibits the general aspect of P. 

 ceylanica (Sowerby), but the sides are much more unequal, and the 

 front one is no broader than the hinder. The groove which runs 

 below the incurved dorsal margin is less narrow thau is usual in this 

 genus. 



4. Description of a New Genus of Shells from the Col- 

 lection OF Hugh Cuming, Esa. By Henry Adams, 

 F.L.S. 



Genus Alora, H. Adams. 



Testa ovato-fusiformis, vix umbilicata, tenuis ; spira elevata ; 



anfractihus convexis^liris elevatis spiralibus et lamellis tenuibus 



cancellatis ; apertura ovali, antice producta ; labia Icevi, ro- 



tundato, antice subrejlexo ; labro margine simplici, acuto. 



Shell ovate-fusiform, slightly umbilicated, thin ; spire elevated ; 



whorls convex, cancellated with elevated spiral ribs and thin lamellae ; 



aperture oval, produced in front ; inner lip smooth, rounded, slightly 



reflexed at the fore part ; outer lip simple, acute. 



Ex. Alora gouldii, H. Adams. 



Trichotropis gouldii, A. Adams. 



This shell, described by my brother as a species of Trichotropis, 

 has been supposed by some to belong to the family Melaniida, and 

 to have been washed down the River Chiriqui, in the Province of 

 Veragua, near the mouth of which the first specimens were found. 

 The Rev. P. P. Carpenter, however, informs me that specimens have 

 since been procured from Panama by Judge Cooper and Col. Jewett, 

 of New York, and that it is truly marine. The genus differs from 

 Trichotropis in the produced, Melania-Yike aperture, and in the 

 absence of a canal.
