N. obliqua, L. sp., var. vertebralis, Batsch, Goes, 1894, K. 

 Svenska Vetenskaps-Akad. Haudl., vol. xxv, No. 9, p. 70, 

 pi. xiii, figs. 698, 699. 



That this form is only a variety of N. obliqua is clearly 

 demonstrated by the present series of specimens. Indeed, it is 

 ■somewhat difficult to satisfactorily separate the variety from 

 the species in some cases. 



Genus Frondicularia, Def ranee. 

 Frondicularia reussi, Karrer. 

 Plate III, fig. 7. 

 Frondicularia reussi, Karrer, 1862, Sitzungsb. d. k. Ak. Wiss. 

 Wien, vol. xliv, p. 441, pi. i, fig. 1. 



Three examples of an ovate, striated Frondicularia were 

 found off Great Barrier Island. They are almost exactly 

 matched by Karrer's figured specimen, from the Miocene of 

 the Vienna basin. The narrowest of our specimens may also 

 be compared with Karrer's F. sculp ta, figured on the same 

 plate as the above. These shells are obviously of the same 

 type as the earlier-described F. annularis of d'Orbigny, ;: from 

 the Miocene of Baden ; this, however, is a generally broader 

 form . 



This appears to be the first occurrence of F. reussi in recent 

 deposits.

Two specimens, one short and stout (typical), the other 

 more elongated, were found in our series. 



Genus Cristellaria, Lamarck. 



Cristellaria tenuis, Bornemann sp.

 Soc. Lond., p. 33. 



A characteristic example of this elegant little cristellarian 

 was found in our sounding. It has also been recorded from
