TUR150. l>()f) 



This is the T. pustulatus of Reeve, preoc. by Brocchi. I add to 

 Reeve's figure of this species, one drawn from a specimen in the 

 Academy's museum. I have a form of T. castaneus which ap- 

 proaches it; and subcastaneus may prove to be a variety of that 

 species; an opinion already advanced by Sowerby Jr. The oper- 

 culum is unknown.

T. FiLosus Kiener, (18 ?) PI. 48, fig. 36 ; pi. 62, fig. 6. 



Shell ovate-conic, umbilicate, spire acute, orange colored, or with 

 longitudinal alternating orange and white flames ; whorls 5-6 ; de- 

 pressed around the upper part, rounded, spirally lirate, the lirse 

 about fifteen on the last whorl, finer beneath, and generally with 

 liruhe in the interstices about the middle portion ; suture impressed, 

 bordered below by a flat tract ; aperture oval, white withm ; colu- 

 mella thickened into an outwardly flaring lip below, and connecting 

 above with a parietal callus which partly covers the umbilicus and 

 is produced in front of the aperture. Alt. 25-26, diam. 23-25 mill. 



Habitat unknown. 



To Kiener's illustration (fig. 36,) I add that of a specimen with 

 longitudinal flames of color, (fig. 6.) 



Operculum (pi. 60, fig. 53,) white outside, and showing an obsolete 

 spiral structure like that of T. spenglerianus. With this species it 

 sc:>ms to be most nearly allied,

 exceeding balance of shell in length ; suture margined ; Iira9 narrow.

 aperture circular, silvery within, columella regularly arcuate, not
