 Typical specimens of this form I have not seen. 



T. CREBRIGRANATUS Reeve. PI. 6, figs. 56, 58, 59. 



Shell unibilicate, conical, elevated, thick, whitish yellow, flam- 

 mulate with roseus; whorls 11 to 12, planulate, the first whitish, 

 eroded, the following spirally cingulate, the cinguli granose, unequal, 

 on the last whorl five, of which the first, fourth and fifth are larger 

 than the others, the fourth most prominent; last whorl slightly 

 elevated, carinate and crenulate at the periphery, planulate beneath, 

 radiately subcostate and concentrically cingulate, the ridges about 

 7, granose ; aperture rhomboidal, lirate within, the basal margin 

 crenated ; columella oblique ; its edge six-nodose ; umbilical area 

 plicate. Alt. 24, diam. 19 mill. (Fischer.) 



Habitat unknown. 



T. crebrigranatus REEVE, Conch. Icon. f. 89, 1861. FISCHER, 

 Coq. Viv. p. 307, t. 97, f. 3. 



In its elongated, narrow form, crenulated periphery, and serrate 

 unequal tubercles, this species is very distinct. (Fischer.) 



T. LINEATUS Lamarck. PL 7, fig. 76. 



Shell false umbilicate, acutely conical ; whorls 9, planulate, whit- 

 ish, ornamented with narrow, close, obliquely descending rosy or 

 purple lines, and sculptured with numerous small, inconspicuous, 

 granose spiral Iira3 ; upper whorls subnodose at the sutures, the lower 

 nearly smooth ; last whorl carinated, a little compressed in the mid- 

 dle, planulate beneath, and ornamented with radiating lines and 8 

 to 9 concentric lirre; aperture rhomboidal; columella straight, with 

 4 or 5 teeth ; basal margin tuberculose within. 



Alt. 40, diam. 38 mill. (Fischer.)

T. lineatus LAM.. An. s. Vert, vii, p. 23. FISCHER, Coq. Viv., p. 

 100, t. 28, 1. 2. T. hanleyanus REEVE, P. Z. S., 1842, p. 184; Conch. 

 Syst., ii, t. 118, f. 11 ; Conch. Icon. f. 2. (Not T. hanleyanus Phil.) 

 f T. eugrammus PHIL., Zeitschr. f. Mai. 1849, p. 153; Conchyl. Cab., 

 p. 299, t. 43, f. 17 (PL 43, figs. 4, 5). 



The T. hanleyanus of Reeve (PL 12, figs. 84 ? 85) may perhaps be 

 considered a variety.
