This is another case of difficulty, arising from incorrect 

 quotations. D'Orbigny has " pi. 4. figs. iiT, i>," which repre- 

 sent small Gasteropods or spiral Annelids, and are further 

 shown to be wrong by the letterpress reference. Turning to 

 pi. 3, the first four figures, H-L, all seem to represent small 

 varieties of Planorhulina ; and as If & I correspond with 

 Soldani' s text-name, quoted by D'Orbigny, we have made 

 our copy from them, and taken them as the basis for determi- 

 nation. 



Figs. iZ, / are probably Planorhulina Ungeriana^ D'Orb. sp., 

 especially resembling its barely separable subvariety known 

 as PI. Akneriana (D'Orb.) ; and /l, L (belonging to Soldani's 

 "Hammonige concavo-unibilicatm^^) seem to he PI. ammonoides, 

 D'Orb. sp.

No locality given. (Fossil at Coroncina, Soldani.) 



This is Pulainulina elegans, a good representative of an 

 important section of the genus. It is not uncommon in deep 

 water, and is often met with as a fossil in Tertiary clays.

" Hob. Fossil at Coroncina." (In the Mediterranean, and 

 fossil at Sienna, Soldani.) 



The large, finely made, many-chambered variety of Rotalia 

 Beccarii, found at Kimini, in the Adriatic. Soldani says of 

 it : — " Omnium hujus speciei Hammoniarum, qu^ hucusque 

 ad manus nostras venerunt, maxima." It differs from R. 

 Beccarii chiefly in its lower surface, which shows the inner 

 turns of the spire to a considerable extent, and is free from the 

 granulation and sutural ruggedness which are usually marked 

 characters in the type. D'Orbigny's locality for the variety 

 as a fossil must stand on his own authority. Soldani men- 

 tions it as a constituent of the littoral sands of the Adriatic,
