56. TURRITELLA NODULOSA. 



T, testa elongato-turritd ; anfractihus striatis ; striis duabus maximis 



subnodulosis ; long. 1|^ ; lat, -J-^ fere ; poll. 



Habitat? Mus. Brit.,nost. 



The two large striae, which are remarkable for the nodules, are not far 

 from the middle of each whorl, and generally are nearer the upper su- 

 ture : of these the lowest is the largest. 



57. MUBEX SALEBROSUS. 



M. testa elongato-ovatd, subalbidd, fasciis fuscis, epidermide cinered ; 

 spird brevi ; anfractibus a7igulatis, nodulosis ; aperturd oblongd ad 

 basin angustd, castaned, intus albd ; labro internh denticulato, den- 

 tibus obtusis albis ; columelld rectdy Icevi ; canali brevi; long.d-^-^; 

 lat. 2 ; poll. 



Habitat? Mus. nost., Geo. Sowerby. 

 This species approaches Murex vitulinus very nearly, the body-whorl 



is very much elongated, and the nodules which mark the angles of the 



whorl are formed of the more elevated parts of what may be termed 



coarse longitudinal plaits. 



58. Murex Rhodocheilus. 



M, testa ventricosd, albd, fasciis elevatis striatis ; septemfariam va- 

 ricosd, varicibus roseis denticulatis ; aperturd rotundatd, rosed, in-
