" Hob. The Adriatic." (Mediterranean and Adriatic, 5b/-

Soldani's figure l'l> i.s a large and much curved Dentalina 

 communis (or narrow Man/inufina lituus) ; fig. cc, which we 

 have copied, only difiVr.^ from }[ar>jinHlina lituus in degree of 

 curvature and in a partial carina on the concave margin of the 

 earlier chambers. 



44. MarginuUna lituus, D'Orb. PI. X. fig. 70.

 bb. D'Orb. op. cit. p. 2o9. no. 11. 



" Hab. The Adriatic." (Mediterranean or Adriatic, Sol- 

 dani.) 



A useful species, embracing the smooth, much-curved, 

 Marginuline Xodosaricr that have many very oblique cham- 

 bers. Soldani and D'Orbigny notice it as a recent form ; but 

 it is not uncommon as a fossil from the Liassic age onwards. 



45. MarginuUna lohata, D'Orb. PI. X. fig. 71. 



"Polvmorplia Subovalia ;" Soldani, Testae, vol. i. pt. 2. p. 115, pi. 117. 

 fig. p. D'Orh. op. cit. p. 259. no. 12. 



" Hoi. The Adriatic." (Mediterranean, Soldani.) 



A short, thick-set, few-chambered Margimdina, with a 

 partial carina on the concave edge, and strongly limbate 

 sutm-es. 



46. MarginuUna consecta, D'Orb. PL X. fig. 69. 



" Nuelei in thalamis Orthoeeratiorum nati ;" Soldani, Testae, vol. i.

^^ Hab. Fossil at Coroncina." (Bovvo Cieco, Soldani.) 



We see no reason to doubt Soldani's statement that these, 

 and several other specimens figured in his fom*th volume, are 

 casts (obtained by the use of acid in some cases), and not 

 perfect fossils. On any other supposition it would be diffi- 

 cult to understand the drawings he refers to. These are casts 

 of straight MarginuUnce. 



* Figs, bb, cc, with other Nodosarice, are described by Soldani as having 

 been obtained from the sea-mud of the Port Ferrajo (Elba) and at the 

 Island Giglio, from the zoophytic coneretions (Tuscan Sea), and from the 

 shore at Rimini (Adriatic) ; but rare at the last place.
