Nodosaria longiscata d'Orbigny, plate XI. figs. 17, 18. D'Orbigny, 

 Foram. Foss. Yienne, 1846, p. 32, plate i. figs. 10, 11. Nodosaria 

 arundinea Scbwager, Sberborn and Chapman, Journ. E. Micros. Soc, 

 ser. 2, vi. (1886) p. 747, plate xiv. figs. 28, 29. Nodosaria longiscata 

 d'Orbigny, Brady, Quart. Journ. Geol Soc, xliv. 1888, p. 6. — Since the 

 critical remarks, in our former paper, on d'Orbigny 's figures, Dr. Brady 

 Las kindly shown us some of the original specimens examined by 

 d'Orbigny, sent to him by Dr. Karrer, of Yienna. We have there- 

 fore had the opportunity of verifying Dr. Brady's conclusion that 

 d'Orbigny, although he figured only the "sugar-loaf" form, included 

 the whole of these smooth, slender, reed-like Nodosarise in one 

 "species." We are much indebted to Dr. Karrer and Dr. Brady for 

 the examination of this form, as the varying conditions of the chambers 

 have unfortunately given rise to almost endless specific naming. 

 Fig. 18 is the particular variety which was named by Terquem 

 N. sublongiscata * ; it shows four chambers, and is unusually perfect 

 compared with the specimens generally found in the London Clay. 

 Fig. 17 is an interesting examj)le, showing the initial chambers. 



Nodosaria sp., plate XI. fig. 19. — The internal cast of two 

 chambers of a Nodosarian, the upper of which shows fine longitudinal 

 striae.

 One of the numerous varieties of Linne's Nodosaria raphanus, figured 

 by Eeuss as N. oligotoma. One specimen. New to the London Clay. 



Nodosaria catenulata Brady, plate XL figs. 21, 22. Brady, 

 Eeport, ' Challenger,' 1884, p. 515, plate Ixiii. figs. 32-34.— The two 

 fragments figured are all that were found. New to the London Clay. 



Nodosaria ohliquata (Batsch), plate XI. fig. 23. Nautilus 

 dbliquatus Batsch, Sechs Kupfertafeln Conch. Seesandes, 1791, plate ii. 

 figs. 5 a, h, c. — Two fragments only found. New to the London Clay.

 Only the fragment figured was found. Not previously recorded from 

 the London Clay.

Vaginulina legumen (Linne), var., plate XL fig. 26. Nautilus 

 legumen Linne, Syst. Nat., ed. 10, 1758, p. 711, No. 248. — This 

 elegant little specimen we regard as a variety of Linne's well-charac- 

 terized " species."
