Allied to F. grceca but constantly far smaller, the apex much 

 nearer the anterior margin, sculpture finer, etc. 



The F. philippiana Dkr. seems to be synonymous. It is figured 

 on plate 42, fig. 55. 



G. dorsata Monterosato is probably a variety. It is an unfigured 

 form, larger than G. gibba Phil., and differing in sculpture. 

 Specimens attain a length of 26 mill. It is from Palermo and 

 other points in the Mediterranean. See Monts., Not. Conch, foss.,
