Reeve, but is of a more depressed form, while the characters of the 

 base, columella, and umbilicus are entirely different, showing it to 

 belong to the section Infundibulum, as distinguished from Lamprostoma.

 Testa transversim elongata, oblique elliptica, leviter compressa, 

 albida, striis minutis numerosis perobliquis sculpta, antice producta, 

 postice brevis, obtuse angulata, rugose concentrice plicata ; umbones 

 acuti, approximati, prominentes, post medium locati ; margo dorsalis 

 utrinque declivis, anticus longus, posticus brevissime spinosus, obtuse 

 angulatus ; margo ventralis arcuatus. Dentes cardinales valvse dextrse

Hah. — I. Monac, New Caledonia. 



An obliquely oval white shell, with prominent and rather acute 

 umbones, situated rather near the posterior end. The surface of both 

 valves is sculptured with oblique striae, mostly very fine, but becoming 

 coarser near the ventral margin ; the sloping posterior dorsal margin 

 is armed with very short blunt spines or scales. 



I know of no species to which this shell bears any close resemblance, 

 though it might be placed near T. gargadia, Linn., which is the type 

 of Bertin's section Quadrans. 



DOSINIA EXILIUM, U.Sp. 



Testa subquadrato-ovalis, insequilateralis, tenuis, convexiuscula, 

 alba, concentrice creberrime lirata ; umbones acutiusculi, approximati, 

 antice inclinati ; margo dorsalis anticus truncatus, posticus levissime 

 declivis, rotunde angulatus ; lunula elongata, paulo impressa ; liga- 

 mentum tenue, immersum. Dentes cardinales 3, divergentes. 

 Impressiones musculorum normales ; sinus pallii trigono-angulatus. 

 Long. 20, lat. 22 mm. 



Sah. — Sarawak, Borneo. 



This fragile white shell bears some resemblance to J), tenuis, Eeclus, 

 an American species, upon which Dr. DalP has founded the genus
