Nodosaria radicula (Linne), dentaline form. (PI. IV, figs. 1-5.) 



This form, which I have found at several localities, has puzzled 

 me for a long time. I have sent specimens to various authorities 

 and obtained different opinions regarding them. Most of the tests 

 are transparent, the others slightly clouded. I am treating them 

 as a dentaline form of N. radicula. Dentalina ohesa Costa, 1856 

 (Atti. Accad. Pontaniana, vol. vii, fasc. 2, pi. xxvii, fig. 13, not 

 described) agrees best with my specimens. Excellent examples 

 occur at Darval Bay, lat. 4° 11' N. ; long. 118° 37' E. ; 315 fms. 



Nodosaria simplex Silvestri. 



Nodosaria simplex Silvestri, 1872, Nodos. Foss. e Viv. d'ltal., p. 95, pi. xi, 



figs. 268-272. 

 N. simplex Brady, 1884, Chall. Eept., p. 496, pi. Ixii.'fig. 4, 5, 6 (?). 



A single typical example. 



Nodosaria sp. ? (PI. IV, fig. 6.) 



The tests are slender. The orifice is phialine in those speci- 

 mens which have a perfect final chamber. There are no signs of 

 spines, but the surface of the last two segments is roughened in 

 several examples. It is possible this may be a nude form of 

 sagrina virgtda which is often without the uvigerine segments. 

 Somewhat similar forms are : N. egregia Eranzenaw (Math, 

 termesz ertesito, 1889. vol. vii, p. 253, pi. 4, fig. 7), and N. annidifera 

 Oiimbel (Abh. m-pl CI. k-bayer. Ak. Wiss. x. 1868 (1870), p. 614, 

 pl. i, fig. 21). 



Nodosaria pyrula d'Orbigny. 



Nodosaria pyrula d'Orbigny, 1826, Ann. Sci. Nat., vol. vii, p. 253, No. 13. 

 N. pyrula Williamson, 1858, Eec. Foram. Gt. Br., p. 17, i)l. ii, fig. 39. 



There are fairly long fragments of well-developed specimens.
