REPORT ON THE FOR AMIN IFER A. 
175 
If my view of the figures of the fossil specimens above referred to be correct, the 
geological distribution of the species extends to the Nussdorf beds of the Vienna Basin 
(d’Orbigny), and the Tertiary clay of S. Alesandro in the island of Ischia (Costa). 
Miliolina separans, H. B. Brady (PL V II. figs. 1-4). 
Miliolina separans, Brady, 1881, Quart. Journ. Micr. Sci., vol. xxi. N. S., p. 45. 
Test irregular in form, angular, outspread ; consisting of several long, slightly inflated, 
strongly costate, Milioline segments. The earlier portion of the test arranged on the 
normal Triloculine or Quinqueloculine plan, the later segments more or less free and 
disposed centrifugally, that is to say, at irregular angles, as though in process of uncoiling. 
Length, y^th inch (2*5 mm.), or sometimes more. 
This is an anomalous and wild-growing, rather than a really dimorphous, variety. It 
may be regarded morphologically as a costate form, such as Quinqueloculina linnceana, 
beginning to unroll itself, but never producing a definite series of straight segments like 
Articulina. 
Of Miliolina separans the Challenger collections have furnished only two specimens, 
those figured on PI. VI I. figs. 1 and 4 ; the former from off Raine Island, Torres Strait, 155 
fathoms ; the latter from a neighbouring locality somewhat to the west, namely, off Booby 
Island, 8 fathoms. But in a little tube of dredged sand, sent to me many years ago by 
the late Dr. Greville of Edinburgh, labelled “ Storm Bay, Tasmania,” Miliolina separans 
was the most prominent species, and the striking appearance of the specimens may be 
judged from figs. 2 and 3 of the same plate.

It is much to be regretted that the classified catalogue of the Foraminifera in the 
Tableau Methodique, which to the systematist is a sort of alphabet of the subject, is 
unaccompanied by any verbal descriptions of the species enumerated, and that, 
consequently, about one-half of the list stands as so much waste labour. Not only so, 
but many of the forms illustrated by models or by the drawings of earlier authors are 
subsequently ignored by d’Orbigny himself, The present species is one of these,
