Art. VI. Fhsus Turtbni Bean, and LimrCea lineata Bean, Two 

 rare and hitherto undescribed Species of Shells, described and 

 illustrated. By William Bean, Esq. 



FususTurtbm Bean, {Jig, 61,) — Shell fusiform, covered 

 with slightly elevated spiral lines broader than the intervening 



spaces, and crossed by 

 numerous longitudinal 

 lines of growth. Length 

 4J in., and about 2 in. 

 broad ; volutions 9, a 

 little raised in the middle, 

 from which they gradually 

 slope to the separating 

 line; aperture ovate, near- 

 ly of the same length as 

 the spire ; canal wide and 

 short; outer lip a little 

 dilated and very thick; 

 inner lip smooth, glossy, 

 and much spread on the 

 pillar. Colour white, 

 covered with a brown epi- 

 dermis, and the inside pale 

 violet. 



This noble and pro- 

 bably unique shell we have 

 named after our old and 

 esteemed friend, Dr. Tur- 

 ton. It was found among 

 the rejectamenta of a boat 

 at Scarborough, and is 

 one of the " great guns" 

 of our collection, which 

 contains (we say it proud- 

 its operculum. ly) 1050 specics and varie- 

 ties, and above 50,000 specimens of genuine native shells.
