Group of Miliolina seminulum . 
Miliolina seminulum Linne sp. 
Serpula seminulum Linne, 1767, Syst. Nat., 12th ed., p. 1264, 
No. 791. Miliolina seminulum (Linne) Jones, 1895, Pal. Soc., 
p. 116, pi. iii, figs. 35, 36. 
Although this grouping of the Miliolinse is far from natural, 
as indeed any system must be which aims at linking together the 
different forms in a linear series, it serves to bring together forms 
which the profusion of intermediate specimens in this collection 
shows to be nearly related. 
In this group, chambers with the rounded transverse section 
cease to be the rule, and in most of the forms the chambers are 
angular or carinate. 
M. seminulum occurs so abundantly in all seas and at all depths, 
that it is needless to specify localities. In the Malay Archipelago it 
is as numerous and as widely distributed as elsewhere. 
Miliolina Auberiana d’Orbigny sp. 
Quinqueloculina Auberiana d’Orbigny, 1839, Foram. Cuba, p. 167, 
pi. xii. figs. 1-3. M. Auberiana (d’Orb.) Goes, 1894, Kongl. 
Svenska Vet.-Akad. Hand!, vol. xxv. p. 109, pi. xix. fig. 844, a-d. 
This stout angular variety is not common in the Malay Archi- 
pelago, and does not appear to have been hitherto recorded from this 
region, although Biitschli in his list gives M. triangularis , which is 
a closely allied variety, differing in little more that the amount of 
acuteness of the periphery. A. Silvestri * records it from two localities 
in the Adriatic.

In his description of this species d’Orbigny states that two or 
three longitudinal striae accompany the keel on each side of it. In the 
figure in the Cuba Memoir these striae are represented, but they do 
not appear in any other of the figures ascribed to this species. The 
Q. Schroelcingerii var. Calabra Seguenza f has the peripheral edges of 
the chambers flattened and striate. The Q. seminuda of Keuss if has 
the periphery rounded and striate; whilst Terquem,§ regardless of
