T. Goldfussii.* Plate 6. Fig. 208. 
Description. 'Turbinolia cuneate, granulate, with twenty- 
four longitudinal furrows; furrows on each side ten, con- 
verging towards a point near to the middle of the base—on 
each edge two, slightly curved and extending nearly to the 
base ; base nearly straight, star elliptical ; lamelle rugose. 
Diam. 3-20ths, Length 5-20ths, Breadth .2, of an inch. 
Observations. ‘This species closely resembles the last. 
The furrows are not, however, so marked, and the two 
curved ones are replaced here by two which converge like 
the enclosed eight. It is not quite so broad, and the base 
is more disposed to be round than emarginate. It seems 
generally to be rather smaller in size. In outline as well 
as in the furrows there is a greater resemblance between 
the Goldfussii and the crispa, than there is between the 
Stokesii and crispa. There being no difference between 
the granulation of the Stokesii and this species, it is not 
considered necessary to make an enlarged view of them. 
T. nana. Plate6. Fig. 209. 
Description. 'Turbinolia subcuneate, longitudinally rib- 
bed ; furrows apparently without perforations ; ribs twenty- 
four, about sixteen of which descend to the base, where 
they are wrinkled ; star elliptical ; style apparently none. 
Diam. 1-20th, Length .1, Breadth over 1-20th, of an inch. 
* Named after Dr Goldfuss, the author of the admirable work ‘ Petre- 
facten,”’ &c.
