 identification.

Station 11. 



Test consisting of two chambers only, furnished with a produced neck 

 covered with thickened bands. Basal chamber bearing in some cases a short 

 spine. The shell-wall consists of two layers, an inner vitreous layer covered 

 with exceedingly fine papillae, which are usually broken off, giving a granular 

 appearance to the clear shell-substance. The outer layer consists of dense, 

 opac^ue, somewhat glistening shell-substance, covering the whole of the shell and 

 extending on to the neck. The shell, when perfect, is of a glistening white 

 appearance owing to this external layer, which is evidently of a very fragile 

 nature, as in many specimens it is denuded in parts, leaving the delicate 

 hyaline inner shell unbroken. 



Dimensions: — Length, • 40- -45 mm. ; breadth, -lomm. 



Confined to Station 11, where several individuals were found, in all stages 

 of denudation.

A single exceptionally large and fine specimen at each. And at Station 0, two 

 specimens much smaller in size and with rounded edges, comparable with L. 

 dentalimformis, Terquem (T., 1869, etc., FOM., 1870, p. 339 (p. 237 in the 

 reprints) pi. xxv, figs, 1-3 ; pi. xxiii, figs. 1-7). The extent and development 

 of the keel in this species has led to the creation of a large number of species. 

 D"Orbigny"s species is found primarily on a figure of Soldani (Testaceographia, 

 1798, vol. ii, p. 37, pi. xii, fig. p, etc.), which shows no trace of carination. 

 D'Orbigny' s figure (1839, FIC. pi. i, figs. 5, 6) also gives no indication of a sharp 

 edge, but the " Modele "" {ut supra) has a sharp edge probably indicating a keel, 

 and is in other respects identical with the type specimen in Paris, which we have 

 examined. We do not attribute much, if any, importance to the carination, which, 

 even in the most extreme examples of the species, only represents the difference 

 between a rounded and a sharp edge, and every intermediate stage between these 

 two may be observed in any extended series of specimens. Still less can we agree 

 with Cushman in forming a new species, L. grandis, on the score of size only 

 (C, 1917, NFP. p. 656 ; and 1919, RFNZ. p. 614). L. carinata is one of the.se 

 species which vary enormously in size.
