580 MESSES. E. HEEON-ALLEN AND A. EAELAND ON THE 



a series of specimens ranging between compressed and cylindrical in section, and both 

 toothed and edentate. The presence of a tooth does not therefore seem to be an 

 essential specific feature. The Kerimba specimens exhibit considerable range in the 

 degree of compression and in the breadth of the shell, but, on the whole, they approach 

 more nearly to Terquem's fig. 12 than to the original " Planche," and they are 

 all furnished with a prominent lamellar tooth. The surface of the shell is highly 

 polished and covered with delicate longitudinal costiE. D'Orbigny's " Planche " of 

 Triloculina cylindrica (d'O. 1826, TMC. p. 300. no. 19 — the type-specimen in Paris 

 is quite typical) represents a similar form with prominent aperture furnished with 

 a tooth, but is markedly triloculiue. The Kerimba specimens are very like the 

 figure of d'Orbigny's Q costata given by Schlumberger (S. 1893, MGM. p. 69, pi. iii. 

 figs. 75, 76), which, however, represents a somewhat more sulcata form and diff'ers very 

 strongly from the original " Planche " of Q. costata d'Orbigny, which has a much 

 longer and more delicate shell. Specimens resembling the " Planche " of Q. costata 

 occur at Kerimba and are dealt with and figured sub M. costata. 



D'Orbigny's "Planche" of Q. parisiensis (F. 1905, SOM, p. 63, pi. ii. fig. 9) is also 

 practically identical with If. striata, but the specific name parisiensis has become 

 identified with Terquem's fossils from the Eocene of Paris, in which the surface of the 

 shell between the sulci is finely punctate. The reasons for the identification of 

 Cuvier's figure of Q. striata (Henderson's Edn., London, 1834, pi. vi. fig. 10) with 

 d'Orbigny's nomen nudum appear to us to be obscure, and the figure is not satisfactory.

Very poorly represented, no typical specimens. Weak specimens are abundant at 

 Stn. 5, and it appears in the adelosine stage at Stn. 9.
