Soldani is manifestly in great doubt about the nature of this 

 arenaceous form. He puts it in a plate amongst " Dubia ac 

 Zoophyta ;" and in his descriptive text we find this note : — 

 " Quae supersunt reliqua, I & K, mihi ignota prorsus sunt, 

 nisi fortass^ K ad Orthoceratis speciem aliquam pertineat." 



D'Orbigny, in accordance with his system of classification, 

 had no alternative but to place it amongst the Dentalince^ and 

 rightly enough gave to it Montfort's specific name, that author 

 having copied Soldani's figure, with the name Reophax scor- 

 piurus. It belongs, however, as we have long ago shown, to 

 an entirely distinct family of Foraminifera, and finds its 

 natural place in the genus Lituola. This species has been 

 already alluded to in a review of the Foraminifera named by 

 Denys de Montfort, Ann. Nat. Hist. ser. 3. vol. vi. p. 346. 

 no. 61 ; see also ibid. vol. v. p. 297.

" Hob. Adi'iatic Sea." (Mediterranean or Adriatic, Soldani.) 



A variety of Dentalina not very commonly met with, but 

 occurring sometimes in habitats favourable to the genus. Its 

 peculiarity consists in the very short longitudinal costge on the 

 constricted portions of the test between the chambers, the 

 prominent parts of the test being smooth. D. intermittens of 

 Roemer and D. Buchi of Reuss also possess these features.

" Hob. Recent in the Adriatic." (Mediterranean, Soldani.) 



A somewhat irregular shell, with a large number of short, 

 compact, cylindrical chambers, marked by a series of stout, 

 unbroken, longitudinal ribs. This is the Nodosaria obliqua^ 

 Linn^, sp. (Ann. N. H. ser. 3. vol. iii. p. 477), coming, of 

 course, under the Dentalina division of the genus, owing to its 

 curvature. There is another " D. obliqua " (see No. 21, a sub- 

 variety oi D. communis) ; but we prefer to keep " obliqua " for 

 Linnd's Dentaline variety of N. raphanusj as above stated, as 

 an early and apt name.
