Sub-genus Ortlioplecta, Beady. 



In this genus there is no coiling of the test, but 

 the segments are otherwise arranged, as in Cassi- 

 dulina. It bears the same relation to the type-form 

 as Nodosaria does to Cristellaria. Uecent. 



Example. — C. (Ortlioplecta) clavata, Brady, ' Eep. 

 " Chall." ' vol. ix. 1884, p. 432, pi. cxiii. fig. 9. 



This interesting but rare form was originally 

 found at Nares Harbour, Admiralty Islands, 17 

 fathoms. The writer has since obtained it from the 

 Funafuti dredgings at 50 to 60 fathoms. Uecent, 

 (Plate 9, fig. U.) 



Genus EliTenhergina, Keuss. 



Test biserial, broad, arched on the dorsal side ; 

 general form that of an unfolded and uncoiled Cassi-

 ' Foram. Amer. Merid.' 1839, p. 57, pi. vii. figs. 21-23.
