the lists of the Post-tertiary Foraminifera of Norway (Sars), of the west of Scotland 
(Robertson), and of the north-east of Ireland (Wright). 
Yerneuilina propinqua, n. sp. (PL XLVII. figs. 8-14). 
Test free or adherent, triquetrous, compressed on three sides ; broad and rounded at 
the oral end, tapering to a blunt point at the aboral extremity ; lateral edges rounded. 
Segments numerous, distinct, inflated ; sutures depressed ; aperture Textularian. Walls 
thick, arenaceous, firmly cemented ; colour brown. Length of large specimens sometimes 
|th inch, 3 ’6 mm. 
It is difficult to define the precise relationship between this form and the species 
last described. The general morphological characters of the two are exceedingly similar, 
but the test in the present case is, comparatively speaking, of very large size, it has thick 
and firmly cemented walls, and betrays a tendency to an adherent habit of growth. It 
may be that the two represent only shallow-water and deep-water varieties of the same 
species, but there is no good evidence of the fact, either in the occurrence of shells with 
intermediate characters or of specimens from intermediate depths. Such examples of 
Verneuilina polystropha as have been found at a greater depth than fifty fathoms retain 
the normal peculiarities of the shallow- water variety. At any rate, so far as at present 
known, the two forms are sufficiently well characterised for easy recognition, and I have 
therefore accorded to the larger type an independent position and a distinctive name. 
Verneuilina propinqua has been observed at five Stations in the North Atlantic, of 
which one is at a depth of 100 fathoms, the other four ranging from 1000 to 2435 
fathoms; at one Station in the South Atlantic, 1900 fathoms; at one in the South 
Pacific, 610 fathoms; and at three in the North Pacific, 95 fathoms, 2050 fathoms, 
and 2900 fathoms respectively. Nothing is known of its occurrence in the fossil 
condition. 
Chrysalidina, d’Orbigny. 
Chrysalidina, d’Orbigny [1846], Carpenter, Brady, Biitschli. 
The genus Chrysalidina was established by d’Orbigny for a type of fossil 
Foraminifera found by him in the Cretaceous beds of the mouth of the Charente, on the 
west coast of France. The single species assigned to it, Chrysalidina gradata, is described 
and figured in the “Vienna Basin” memoir p. 194 (pi. xxi. figs. 32, 33), and was apparently 
to have been included in the unpublished 5th Livraison of the author’s models of 
Foraminifera. The figures referred to represent a tapering, triserial, Textularian 
shell, nearly circular in transverse section, with somewhat numerous short segments
