Fusus multicostatus. Plate V, fig. 6, 6 a. 



F. Testa parvd, turritd, turbinatd, anfractibus convexis (5 — 6), suturisprofunde separatis; 

 costis longitudinalibus numerosis, obliquis, striis transversis, crebris; aperturd parvd, caudd 

 breviusculd. 



Shell small, turreted, turbinated ; whorls very convex, 5 — 6 in number ; the sutures 

 being deeply impressed, the costae are longitudinal, rounded, and directed obliquely from 

 left to right; there are also numerous closely-arranged transverse striae; the aperture is 

 small, the canal short. 



Locality. The planking bed of Minchinhampton Common has afforded this pretty 

 little species : it is moderately rare. 



Fusus coronatus. Plate V, fig. 5. 



F. Testa parvd, turritd, anfractibus convexis, angustatis et nodulosis {nodulis 9), parte 

 superiori transverse trilineatis; anfractu ultimo ventricoso ; basi Icevi, caudd subrectd. 



Shell small, turreted, whorls convex, narrow, and nodulated ; nodules about 9 in a 

 volution, with three encircling lines beneath the middle of each volution ; the last whorl is 

 ventricose, the caudal extremity nearly straight. 



The general aspect of this little species has some resemblance to a Bostellaria; there 

 does not appear, however, to be any expanded wing or other characteristic features of that 

 genus. 



Locality. It is very rare. We have obtained only three specimens, which occurred in 

 the planking of Minchinhampton Common. 



Fusus? sub nodulosus, D 'Orb. Plate V, fig. 9, 9a. 



Fusus subnodulosus, I? Orb. 1850. Prod. Paleont., p. 303. 

 — nodulosus, Deslong champs. M£m. Soc. Linn. Normandie, vol. vii, pi. 10, 

 figs. 36, 37. (Not Sow., 1837.) (Not Lamarck.) 



F. Testa minutd, ovato-turritd, acuta ; anfractibus rotundato-inflatis, transverse striatis, 

 nodulis (6) subobliquis, longitudinalibus; columella marginatd, aperturd ovatd, caudd 

 breviusculd. 



Shell minute, ovately turreted, acute; whorls rounded, tumid, transversely striated; 

 nodules 6 in a volution, longitudinal, and rather oblique ; columella marginated, aperture 

 ovate, caudal extremity short ; length, 3 lines. 



The transverse striae are not mentioned by M. Deslongchamps ; but in the specimen 

 which we have figured they are very distinct.
