T. cernicus Sowerby, 1886, (pi. 44, fig. 81,) "Shell ovate conic, 

 solid, subventricose, imperforate, yellowish, longitudinally flammulate 

 with reddish-brown ; spire acute, elevated; whorls convex sloping 

 above, minutely obliquely striate, encircled by wide flattened ribs, 

 alternating with smaller ; last whorl obtusely angulated above, 

 lightly depressed above the angle, scarcely canaliculate ; aperture 

 circular, lip acute, scalloped ; columella thick, convex, slightly 

 arcuate and slightly produced at base, longitudinally plicated." 



"Operculum very convex outside, green, suffused with bright 

 reddish-brown, conspicuously granulose." Sowerby's figure, copied 

 on my plate, is two-thirds natural size. 



Specimens before me from Mauritius, of this species, are rather 

 smaller than Reeve's figure ; the broad flat ribs, and brown opercu- 

 Itim, conspicuously granulose in the middle, are the more prominent 

 characters. 



T. SPLEXDIDULUS Sowerby, 1886. PL 44, fig. 72. 



"Shell large, ventricose-conoid, imperforate, orange-brown, white 

 and brown punctate and variegate ; spire small, acute, gradate ; 

 suture scarcely impressed ; whorls about 61, above concavo-planate, 

 then convex, longitudinally obliquely striate, spirally lirate, the 

 lino numerous, unequal, about 15 on penultimate whorl, the first 

 (subsutural) prominent, subnodulose, brown and white articulated ; 

 base convex, smooth, subobsoletely sulcate, overspread by white 

 and dark brown maculations ; umbilical region with a -white and 

 orange callus ; aperture subamplp, circular, throat silvery." (Sower- 

 by.} Habitat unknown. 



Described from a single specimen of unknown origin.

Shell conoid, imperforate, spirally lirate, smooth, pale flesh

 about nine in number on the body-whorl, alternately smaller, 

 the third much elevated forming an angle; Iira3 of base slightly

T. AKCYKOSTOMUS Linn-, 1758. PL 40, fig. 18; PL 42, fig. 41; 



PL 46, fig. 8. 



Shell large, ovate-pointed, solid, whitish, irregularly maculated 

 with greenish and brown; whorls 6, convex, separated by subcan 

 aliculate sutures, the upper two smooth, the lower spirally lirate an- 

 radiately more or less squamose striate, body-whorl with ab. 

 thirteen lira?, which are generally wider than their interstices, 

 of which the subcoronal and one or two median ones are moi<
