1876.] MR. G. B. SOWERBY ON NEW SHELLS. 753 



fasciis castaneo-fusco longitvdinaliter strigatis, aliter lineis 

 aurantiacis eximie trigono-reliculata ; spira pyramidali, anfrac- 

 iibus leviter spiraliter sulcatis ; apertura august a, alba. 



Long. 60, lat. maj. 20 mill. ; spira alt. 19 mill., apertura lat. maj. 

 5, min. 2 mill. 



Hab. Mauritius. 



Shell elongated, rather solid, obsoletely striated, very obtusely 

 angulated behind, and gracefully attenuated to the front, whitish, 

 with broad interrupted bands of orange, longitudinally streaked with 

 chestnut-brown, intersected by an exquisite network composed of tri- 

 angular orange lines ; spire pyramidal, whorls faintly spirally grooved ; 

 aperture narrow, white. 



This beautiful species, belonging to the interesting collection of 

 the Marchioness Paulucci, of Florence, forms a striking addition to 

 the subgenus Cylinder, or " textile " group of Cones. In general 

 form it resembles C. gloria-maris ; but it differs from that valuable 

 species in the formation of the spire, the whorls being much less 

 concave and the angle of the body-whorl more rounded. In colour 

 and marking it closely resembles C. aureus ; but it is of a much more 

 tapering form than that species, and its surface is much smoother.

C. testa oblonga, solidiuscula, angulata, turgidula, Icevi, antice 

 valide sulcata, albida cceruleo tincta, maculis grandibus fulvis 

 irregulariter ornat a, fasciis frequentibus angustis maculatis et 

 quasi literatis cincta ; spira abbreviata, fulvo strigata, anfrac- 

 tibus concaviusculis, spiraliter sulcatis; apice acuto, roseo ; 

 apertura subangusta, fauce purpureo-fusco tincta. 

 Long. 27, lat. 14 mill., apert. lat. maj. 4, min. 2 mill. 

 Hab. Madagascar. 



Shell oblong, rather solid, angular, somewhat swollen, smooth, 

 strongly grooved in front, whitish tinged with blue, irregularly orna- 

 mented with large yellowish blotches, and encircled with numerous 

 narrow bands composed of letter-like spots ; spire short, marked 

 with radiating stripes of the same tawny colour as the spots on the 

 body-whorl, whorls rather concave, spirally grooved ; apex acute, 

 rose-coloured ; aperture rather narrow, interior tinged with purplish 

 brown. This shell also belongs to the Marchioness Paulucci, and is 

 the only specimen I have seen. Though of simple form, it is quite 

 distinct from any hitherto known species. Its bluish tinge of colour 

 and delicate letter-like markings are remarkable. 



Conus baccatus, sp. nov. (Plate LXXV. fig. 5.) 



C. testa abbreviato-turbinata, turgidula, minutissime decussata, 

 conspicue seriatim granulata, albida, maculis aurantiacis grandi- 

 bus trifasciata ; spira acuta, brevi ; anfractibus cone avis, fere 

 Icevibus, ultimo biangulato. 



Long. 23, lat. maj. 15 mill. 



Shell short, rather swollen, very minutely decussated, with regular 

 rows of conspicuous granules, whitish, with large orange blotches
