the Nomenclature of the Foraminifera. 159 



various authors, in our ' Monograph of the Foraminifera of the 

 Crag-.' The oldest name given to this variety was Lamarck's 

 '■'■ Nodosaria dentalina^'' and apt enough with that quasi- 

 generic prefix ; but the inconvenience of the trivial being the 

 same as the subgeneric name, and the wide acceptance of 

 D'Orbigny's term, have induced us to retain the latter.

" Hah. Recent in the Adriatic." (Mediterranean or Adriatic, 

 Soldani.) 



See note on the same variety in our paper on the " Models " 

 (Ann. N. H. ser. 3. vol. xvi. p. 19). We ought to have there 

 added that the trivial name had been preoccupied by Linne 

 for the Dentaline form of N. Rajyhanus ( =D. Ouvieri, D'Orb.). 



D'Orbigny's reference to another of Soldani's figures (pi. 

 107. fig. .^) is obviously an error.

^^ Hah. Recent in the Adriatic." (Mediterranean, ;S'o?f?am.) 



A much-curved, smooth Dentalina^ with the chambers set 

 on very obliquely ; the chambers inflated and distinct on the 

 convex side of the shell, but gradually thinning towards the 

 concave margin. In Soldani' s figure the shell appears to 

 be bordered by a smooth even carina on the concave side. 



23. Nodosaria {Dentalina) carinata^ D'Orb. PI. IX. fig. 50. 



" Orthoceras ohliquum ;" Soldani, Testae, vol. i. pt. 2. p. 98, pi. 105. tig. N. 

 D'Orb. op. cit. p. 255. no. 39. 



'■'•Hah. The Adriatic Sea." (Mediterranean or Adriatic, 

 Soldani.) 



A somewhat similar variety to the last {D. arcuata) ; indeed, 

 if we do not place the two under the same trivial name, it is 

 only from the desire to give our author the benefit of a doubt. 

 It is a long, slender Dentalina., with a large number of very 

 oblique chambers, and an apparently well-defined carina of con- 

 siderable width running the whole length of the concave side.
