The following varieties are diagnosed by Dr. Fischer : 



Var. /3. Form normal ; umbilical area not margined witli green. 

 Var. MEDERi Fischer. PI*. 12, figs. 66, 67. 



More elongated, ornamented with wide deep brown longitudinal 

 bands, the spiral lirie of the base separated by intermediate lirulse. 



Alt. 19, diam. 21 miU. 



Avon Is. 

 T. NiGROPUNCTATUs Reeve. PL 42, figs. 2, 3. 



Shell rather largely, excavately umbilicated, shortly conical, ash- 

 green, obliquely flamed with black ; whorls flatly convex, spirally 

 very closely gemmed with regular grains ; base grain-ridged, inter- 

 stices crispately decussated, ridges dotted with black ; dots conspic- 

 uous, distant. (Reeve.) 



Natal 



T. nigropimc'taius RvE., Conch. Icon., f. 71. (1861.) — T. hanley- 

 anus Philippi, Conchy I. Cab., t. 16, f. 2. (not T. hanleyanus Rve.) 

 T. subvirklis Philippi, Zeitschr. f. Mat, 1848, p. 126. — Conchyl. 

 Cab., p. 259, t. 38, £ 7. (pi. 42, figs. 4, 5.) 



The surface of this species is grained with unusual regularity, and 

 the base is very characteristically S])rinkled at rather distant inter- 

 vals with blue-black dots. {Reeve.) 



I consider the locality doubtful. 



T. KOCHii Philippi. PI. 5, figs. 36, 37. 



Shell conical, broad, rather solid ; spire conic, apex generally 

 eroded, corneous or orange colored ; whorls about 7, a little convex, 

 whitish, painted with oblique flexuose or angular brownish green 

 radiating stripes, nearly the whole surface sometimes suflfused with 

 bright green by the erosion of the outer layer ; the sculpture consists 

 of inconspicuous incremental stride and very oblique subobsolete 

 folds ; base very obsoletely Urate; flat, the middle portion (umbilical 

 tract) excavated, concave, strongly spirally grooved, the sculpture 

 not extending into the aperture nor to the edge of the columella, 

 which is nacreous ; aperture very oblique, large, very iridescent and 

 neither Urate nor toothed within ; basal lips and columella simple, 

 forming a regular curve ; columella with a strong dentiform fold 

 above ; parietal wall eroded, green, nearly smooth. 



Alt. 32, diam. 38 ; alt. 28, diam 40 mill. 



Indian ; Red Sea.
