NODOSARIINAE 383 



Sub-family NODOSARIINAE 



Genus Nodosaria, Lamarck, 18 12 



Note. Nodosariae with basal spines are not uncommon, but the Falkland material has 

 furnished specimens of N. laevigata and rotiindata in which the spinous outgrowths 

 attained a development which we have not seen elsewhere, and which does not appear to 

 have been figured by other authors, although Millett has figured A'^. laevigata with fine 

 spines (M. 1898, etc., FM, 1902, pi. xi, fig. i), also Cushman (C. 1910, etc., FNP, 1913, 

 pi. xxiv, fig. i) and Flint (F. 1899, RFA, pi. Iv, fig. 3) have figured L. rotiindata with one 

 or more stout basal spines. In the Falkland specimens, however, these spines attain a 

 length and strength which constitute a very remarkable and outstanding feature of the 

 test. We do not regard this spinous ornament as having any specific or varietal value : it is 

 no doubt connected with the depth and conditions of the deposits. 



247. Nodosaria rotundata (Reuss) (Plate XII, fig. i). 



Glandtdina rotundata, Reuss, 1849-50, FOT, p. 366, pi. xlvi (i), fig. 2. 

 Nodosaria (G.) rotundata, Brady, 1884, FC, p. 491, pi. Ixi, figs. 17-19. 



Six stations: 230, 235, 236; WS 99, 408, 433. 



The normal type is found only at WS 99. At all the other stations the specimens are 

 large, and strongly spinous. 



Length, 1-32 mm. without spines, which are more than 0-15 mm. long. 



248. Nodosaria laevigata, d'Orbigny (Plate XII, fig. 2). 



Nodosaria (G.) laevigata, d'Orbigny, 1826, TMC, p. 252, no. i, pi. x, figs. 1-3. 

 Nodosaria (G.) laevigata, Brady, 1884, FC, pp. 490, 493, pi. ixi, figs. 17-22, 32. 

 Nodosaria (G.) laevigata, Millett, 1898, etc., FM, 1902, p. 509, pi. xi, fig. i. 



Three stations: 235 ; WS 215, 408. 



The best at WS 408, where the specimens bear from one to many spines. Length, 

 1-45 mm. without spines, which were probably 0-20 mm. in length when perfect. The 

 Type is missing. 



249. Nodosaria radicula (Linne). 



Nautilus radicula, Linne, 1767, etc., SN (ed. xii), p. 1164. 

 Nodosaria radicula, Brady, 1884, FC, p. 495, pi. Ixi, figs. 28-31. 



One station: WS 215. 



A single specimen. 



250. Nodosaria scalaris (Batsch). 



Nautilus (Orthoceras) scalaris, Batsch, 1791, CS, p. 2, pi. ii, fig. 4. 



Nodosaria scalaris, Brady, 1884, FC, p. 510, pi. Ixiii, figs. 28-31 ; pi. Ixiv, figs. 16-19. 



Nodosaria scalaris, Cushman, 1910, etc., FNP, 1913, p. 58, pi. xxiv, fig. 7. 



Seven stations: 388; WS 71, 83, 88, 93, 221, 408. 



Never very abundant, the best at WS 83. The general type at all the stations is similar 

 to those commonly found in British dredgings, in which the sides of the test are practi-
