 tened laterally so that the spire is distinctly gradated. Usually a row of 

 small tubercles on the keel, about 10 on a whorl. On both sides of the 

 keel the whorls are deeply spirally grooved ; three or four grooves behind 

 the keel, and four or five in front of it, on the spire whorls. Body 

 whorl with about ten spiral grooves in front of the keel ; the anterior part 

 of the shell is spirally striated only. Aperture ovate ; inner lip with a 

 large continuous callus, the columella slightly bent ; outer lip reflexed, pro-

Distinguished from T. scutum by its great height ; but intermediate 

 forms occur. 



Eglisia striolata. 



Shell minute turreted. Whorls 8, rounded, the suture deeply impressed, 

 delicately spirally striated ; two of the striations usually more prominent 

 than the rest ; sometimes almost smooth. Aperture broadly ovate or sub-
