Miocene, Anguilla. Allied to P. peedeensis Tuomey and 
Holmes, North America. 
Spondylus bo stry chiles n. sp. 
5 ‘. bifrons Sow. (non Goldfuss) Quart. Journ. Geol. Soc., 
vol. vi.. p. 53. 
A species found in Haiti and Anguilla. As the name 
bifrons had been already given by Goldfu.ss to a .species of 
the same genus it is necessary to change the name. 
Pentacrinus rotularis n. sp. 
No other part than the stem of either of the species here 
named has been discovered. The stem of P. rotularis is cir- 
cular in section, compo.sed of numerous joints whose dia- 
meter is rather more than thrice their height. 
Lower Miocene, San Fernando. 
Pentacrmus obtusus n. sp. 
Stem angular, somewhat irregularly pentagonal in sec- 
tion ; joints about mill, high and about 4^ mill, in 
diameter. 
The differences between the stems to which I have as- 
signed these names and all other species of w^hich I have 
any knowledge seem to be sufficient to warrant the creation 
of provisional specific appellations.
