Krister described his species from young specimens ; there can 

 be no doubt, however, of its identity with the forms subsequently 

 characterized by Reeve as T. lauta (fig. 574), and T. leucodesma 

 (fig. 575). Reeve's figure of T. pardalis is a Columbella. 



T. MEDCOMACULATA, Sowb. PI. 55, figs. 581, 582. 



Somewhat indistinctly plicately ribbed, ribs smooth, wide, 

 close together, interstices with revolving striae ; sculpture alto- 

 gether obsolete on the back of the last whorl ; rich chestnut- 

 brown, broadly white-banded, with a row of square, regular 

 brown spots in the centre of the band. Length, -5 inch. 



Mauritius. 



T. Cernica, Nevill (fig. 582) is a synonym. 



T. PUELLA, Reeve. PL 55, fig. 583. 



Dark chestnut or chocolate with jagged flames or spots of 

 white, frequently confluent around the suture Surface polished,

West Indies. 



T. TURTURINA, Souverbie. PL 55, fig. 584. 



Smooth, polished, solid, columbelliform, with revolving striae; 

 dark chestnut, with small white revolving points or spots. 



Length, *5 inch. 



Loyalty /., New Caledonia. 



Resembles the preceding species, differing in its columbelli- 

 form aperture, and the disposition of the spots. 



T. CREMANS, Reeve. PL 55, fig. 585. 



Dark chocolate, with an irregular white band, tending to 

 spread longitudinally on the tops of the distant folds or ribs, 

 these being sometimes obsolete ; irregularly white-banded near 

 the base ; when the shell is fresh, close, very fine spiral lines are 



visible. Length, -5-'6 inch. 



Philippines. 



The figures of Sowerby and Reeve are both taken from smooth 

 uncharacteristic specimens. It is near T. pardalis. M. Timo- 

 rensis, Dohrn, an unfigured species, from the island of Timor, 

 is apparently synonymous. 



T. ALVEOLUS, Reeve. PL 55, fig. 586. 



Longitudinally finely ribbed, base with revolving grooves ;
