G. testa oblongo-turrita, solidiuscula, leevigata, obscure nitida, fusco-cornea ; spira turrita, apice obtusiusculo, sutura impressa, crenulata; anfr. 7, convexiusculis, ultimo -| paulo superante; apertura parum obliqua, ovali; columella callosa, valde arcuata, oblique truncata; perist. recto, obtuso, albido marginato, marginibus callo tenui junctis. Long. 81, diam. 4 mill. Hab. Sattara, Bombay (Coll. F. Layard). VITRINA ANGASI, H. Ad. (Pl. IV. fig. 11.) V. testa imperforata, subdepressa, peripheria auriformi, tenui, superneplicato-striata, non nitente, rufo-fulva, subtus lavigata, nitida, olivacea; spira paulum elevata, sutura distincta, albo marginata; anfr. 4, convexiusculis, ultimo magno, ad peripheriam compresso ; apertura valde obliqua, ovali, intus leviter margaritacea; perist. simplici, amplo, anguste membranaceo marginato, brerissime inflexo, marginibus conniventibus, dextro extrorsum valde dilatato, columellari arcuato. Diam. maj. 33, min. 26, alt. 20 mill. Hab. Capengo, West Africa (Coll. H. Adams). This fine species most nearly approaches V. fiemingii, Pfr., from India; but the aperture is more ample and depressed, the right margin more dilated, the last whorl more compressed at the periphery, the spiral lines on the whorls are absent, and the colour of the upper portion is red-brown instead of olivaceous. It differs from the other large African species, V. soiverbyana, Pfr., in the last whorl being less angulate, in the spire being considerably more raised, and in the aperture being less oblong. NANINA (XESTA) SULCIFERA, Barcl. MS. (Pl. IV. fig. 12.) N. testa imperforata, semigloboso-conoidea, solida, spiraliter distantibus, et longitudinaliter striis obliquis confertis fulvo-rubida; spira conoidea, apice acutiusculo, sutura leviter impressa ; anfr. 5, convexiusculis, ultimo antice deflexo, infiato, basi subconvexo; apertura valde obliqua, ovali; perist. simplici, incrassato, marginibus conniventibus, callo junctis, columellari dilatato, excavato. Diam. maj. 40, min. 32, alt. 30 mill. Hab. Montagne-au-Riz, Mauritius (Coll. Barclay). " This interesting species has not, to my knowledge, been found alive, and would appear to be extinct.
