Ace. Sci. 1st. Bologna, ser. v, vol. x, p. 300, pi. 0, fig. 2. 



The recent examples are better known under the name of 

 T. aspera, Brady, which is, however, identical in its essential 

 characters with the earlier-described T. tuberosa. Our speci- 

 mens have the ruddy-brown tests similar in colour to the 

 examples found in North Atlantic. 



Genus Spiroplecta, Ehrenberg. 

 Spiroplecta sagittula, Def ranee sp. 



Textularia sagittula, Defrance, 1824, Diet. Sci. Nat., vol. xxxii, 

 p. 177 ; 1828, vol. liii, p. 344 ; Atlas Conch., pi. xiii, fig. 5. 



Spiroplecta sagittula, Defr. sp., J. Wright, 1891, Proc. R. 

 Irish Acad., p. 471. 



This species and the following variety attain to a great 

 length in this deposit, some of the specimens measuring 4 mm. 

 T. sagittula was found off the coast of New Zealand (sta. 169) 

 by the " Challenger." 



Spiroplecta sagittula, Defr. sp., var. fistulosa, Brady. 



Plate III, fig. 4. 



Textularia sagittula, Defr., var. fistulosa, Brady, 1884, Rep. 



Chall., vol. ix, p. 362, pi. xiii, figs. 19-22. 



This variety is much more abundant in the present series 

 than the specific form, and attains approximately the same 

 length. 



Genus Clavulina, d'Orbigny.

Clavulina communis, d'Orbignv. 1826, Ann. Sci. Nat., vol. vii, 

 p. 268, No. 4. Brady, 1884, Rep. Chall.. vol. ix, p. 394,
