This may be accepted as a convenient subvarietal term for 

 a Dentaliuc A', raphanus [D. ohh'qua), iKiving a smootli glo- 

 bose primordial segment, larger than tho.se that immediately 

 follow. The later chambers rapidly increase in size ; the last, 

 or tenth, is nearly twenty times as long as the second.

" Hab. The Adriatic." (Fossil near Sienna, Soldani.) 



A very short wide Frondicularia ; the lower ends of the 

 chaml)ers irregular and ])ointed. We doubt the locality given 

 by D'Orbigny for Frondicidaria in a recent state (see Quart. 

 Journ. Geol. Soc. vol. xvi. p. 800). If Frondicularioi were 

 foimd by him in the shallow lagoons of the Adriatic, they 

 must have been derived from Tertiary clays. Soldani speaks 

 of this species as common in the fossil state in the clays of 

 San Quirico, Monte Ilco, and the neighbourhood of Sienna.

" Hab. Fossil at Coroncina." (Near Sienna, Soldani.) 



This appears to be a passage-form between Frondicularia 

 and LinfjuUna. Such specimens are not uncommon ; and it 

 may be convenient, therefore, to retain the name.
