is subject to great variation, being smooth in some examples, 

 whilst others are beset with tubercles and spines in various 

 degrees. The peripheral margin is more or less fimbriate and 

 often deeply indented at the sutures. A series of umbilical lobes 

 is always present. 



The example illustrated shows all these characters in a modified 

 form.

 B. papulosa (Brady) Flint, 1899, Eep. U.S. Nat. Mus. for 1897 

 (1899), p. 322, pi. Ixxvi. fig. 2. 



At Station 13 in Area 1 this form is common, and it occurs 

 sparingly at a few other Stations in both Areas. 



Brady states that it was obtained at seven 'Challenger' 

 Stations in the South Pacific, and at one in the North Pacific, at 

 depths of from 2 to 37 fathoms. The ' Albatross ' locality is not 

 recorded. 



Botalia annectens Parker and Jones, plate X. fig. 6.

 pp. 3S7, 422, pi. xix. fig. 11. 



Parker and Jones describe this as " A well-developed conus- 

 shaped Eotalia, which has on its under or umbilical surface,, 

 partially formed secondary chambers, owing to angular processes 

 of the septa nipping the umbilical lobes. It is thus a passage- 

 form between B. Schroctcriana P. and J., and B. (Aster igcrina) 

 lobata d'Orbigny." The localities given are Hong Kong (anchor- 

 mud) and Fiji (coral-reef). 



The Malay examples are less conical than the type, and the 

 angular processes of the septa are not so well marked. 



It occurs sparingly at Stations 14 and 17.

plate X. fig. 7. 



This is a neat compact form, subject to but little variation. 

 The sutures on the inferior face of the test are deeply excavated, 

 forming angular depressions which increase in width as they recede 

 from the peripheral margin. They are bordered by two rows of 

 tubercles, which combine to form a zigzag beading encircling the 

 test. The supplementary chambers are obtuse on the superior 

 margin, and usually cover the whole of the umbilical region. In 

 the example selected for illustration these lobes are absent from
