7 Stations. 



Rare, except at Stn. 7. Most of the specimens are small. There are two t)'pes, one 

 short and broad, the other long and narrow ; the long and narrow form at Stn. 10 

 shows signs of passing into Terquem's B. elegantissima, var. seminuda, the chambers 

 being short and the spire considerably drawn out. At Stn. ] X an abnormally lonj; 

 specimen was found. 



200. Bulimina elegantissima, var. compressa Millett. (PL XLVIII. figs. 

 23-30.) 



Bulimina elegaiitissima, var. compressa Millett, 1898, etc., FM. 1900, p. 277, pi. ii. fig. 5. 

 13 Stations. 



Generally distributed, but not many individuals, except at Stns. 2 a and 11. There 

 are two distinct types, one of which closely resembles Millett's figure, the other 

 being much broader towards the oral extremity and more distinctly bolivine in 

 outline. The marginal edge of the broad form is often strongly lobulate, the best 

 specimens of this form were obtained at Stn. 2 a. At Stn. 3 a specimen was observed 

 in which the terminal chamber consisted of a large expanded "balloon" similar to 

 Sidebottom's figure of B. elegantissima, var. seminuda (S. 1904 etc., EFD. 1905, 

 pi. iii. fig. 2). At Stn. 11 a specimen of the narrow type was found in association 

 with a minute individual consisting of three chambers only C? budding), and at 

 Stn. 7 several individuals with the terminal chamber broken and the internal septa 

 dissolved which had evidently been in association with others.. At Stn. ■? B some 

 specimens exhibit curvature of the longitudinal axis as in Bolivina tortuosa Brady. At 

 Sin. 11 specimens with the young "budding" individual attached were found.

Universally distributed, very common at Stns. 1 and 2. Three well-marked types are 

 noticeable, a short stout acutely pointed form, a long narrow acutely poiniedlorm, and
