MOEMULA EXCELLENS, D.Sp. PI. XXV, Fig. 10. 



Testa elongata, solidiuscula, pallida, zona fusca infra suturam 

 basimque ornata ; anfractus 14-15 ; embryonales sinistrorsum contorti, 

 caeteri planato-convexi, plicis longitudinalibus numerosis confertis 

 planulatis, liris spiralibus densissimis cancellati ; penultimus varice 

 latiusculo munitus ; ultimus ^ longitudinis testae vix sequans, ad basin 

 rotundatus, prope aperturam lativaricosus ; apertura subovata, intus 

 laevis, obscure f usco fasciata ; columella leviter contorta, vix plicata. 

 Long. 15, diam. 3-3 mm. 



Hah. — Monac Island, New Caledonia. 



A handsome species of the small limited genus Mormula. It has 

 somewhat the form of M. MacAtidretvi, A. Adams, but more whorls, 

 the longitudinal plicae are closer, and it is distinguished by the bright 

 brown infrasutural band ; it has a rather broad varix on the pen- 

 ultimate whorl ; the numerous ridges crossing the longitudinal plicae 

 give them a granular appearance. I have only seen three specimens 

 of this interesting species, of which the type is the largest, a young 

 one showing the curiously contorted apex, and an intermediate one 

 with paler colour-bands. 



SoLETELLINA HeDLEYI, U.Sp. PI. XXV, Fig. 12. 



Testa transversim elongata, elliptica, tenuis, pellucida, albida, 

 concentrice subtilissime irregulariter plicata et striata, postice pallide 

 f ulvo-radiata ; umbones minuti, conjuncti, post medium locati ; margo 

 dorsalis anticus longus, rectiusculus, levissime declivis ; posticus 

 brevior, paulo magis declivis, utrinque rotundatus ; ventralis leviter 

 arcuatus ; ligamentum externum, corneum, elongatulum ; dentes 

 cardinales valvae dextrse duo, divergentes, in valva sinistra duo 

 quoque, antico acuto, bifurcate, postico lamellari ; sinus pallii magnus, 

 linguae formis. Long, (umbone ad marg. ventralem) 12, lat. 23 mm. 



Hab. — South Australia. 



A transversely, elongated, thin, pellucid shell ; faintly rayed 

 posteriorly. The species has long passed muster in Australian 

 collections for Sanguiyiolaria vitrea, Desh., with which it has scarcely 

 any affinity ; and 1 am indebted to Mr. Hedley, of the Australian 

 Museum, after whom I have pleasure in naming it, for confirming my 

 opinion that the species has not hitherto been described. 



Aeca (Scapharca) Fultoni, n.sp. PL XXV, Fig. 11. 



Testa transversim elongatula, obliquiuscula, leviter inaequivalvis, 

 lateribus superne angulatis, antico infra rotundato, postico oblique 

 rectiusculo, alba, epidermide scabrosa induta, costis radiantibus 

 pernumerosis (circa 47) angulatis, rugosis, sulco angusto divisis 

 instructa ; margo dorsalis rectus ; area ligamenti angustiuscula ; 

 umbones convexi, incurvati, ante medium locati; cardo normalis. 

 Long, (umbone ad marg. ventralem) 35, lat. 50 mm. 



Hab. — Manila, Philippines. 



Distinguished from its congeners by the large number of its radiating 

 ribs, which are rather angular, crenulated, and divided by a central 

 groove. Area crehricostata, Reeve, has almost as many ribs, but they 

 are broader and closer together ; that species is also equivalve and so 

 delegated to the section Anomalocardia.
