(PI. II, fig. 24) I take to be the same as that figured by Millett. 

 The tests, however, are more pointed and the chambers more 

 numerous and narrower than in Millett's example. Two occur. 

 They appear to be in the microspheric condition. 



The other form (Ph II, fig. 25) may also be Millett's variety in 

 the megalospheric condition. It is more oval in shape, and the 

 final chambers are not so much inflated. Seven occur. 



Under this name Eeuss figured two very dissimilar forms. His 

 fig. 40 agrees with Brady's figs. (PL xlvi, figs. 17-19), and with 

 recent specimens from the Indian Ocean. Millett's figure appears 

 to be based on Eeuss's fig. 42, but the structure is quite different. 

 Millet's gaudryine chambers are confined to the apex, hardly 

 noticeable, while the Eeuss type shows a triserial cone from apex 

 to aperture. The " Dart " specimens are very variable ; one is 

 similar to the " Challenger " type, the others approximate more 

 nearly to Millett's figure, and may possibly represent only 

 gaudryine varieties of Textularia concava (Karrer).

The specimens are not typical, being more slender than the 

 " Challenger " example. Several of the tests have six pairs of 

 Textularian chambers of the typical ferruginous colour, except the 

 final pair, which are of greyish hue. One specimen is grey through- 

 out. The triserial portion is obscure, and the arrangement may 

 be Textularian throughout the entire length of ihe test, but the 

 irregularity of the initial portion suggests a different manner of 

 growth. In addition to the above, there are two minute tests, one 

 grey, the other brown, in which the triserial commencement is well 

 marked and the biserial portion slightly twisted. These may or 

 may not belong to this species. 



Valvulina d'Orbigny. 

 ValvuUna fusca (Williamson). 



Rotalina fusca Williamson, 1858, Rec. For. Gt. Br., p. 55, pi. v, figs. 114, 115. 

 Valvulina fusca Brady, 1884, Chall. Eept., p. 392, pi. xlix, figs. 13, 14. 



I believe I am right in placing these three tests under this 

 heading. They are very minute, and the chambers (of which 

 there are three in the last whorl) are slightly inflated. They are 

 remarkable for their beauty. When lit up by a strong light, the
