The Gaudryina chilostoma of Reuss differs from the typical Gaudryina pupoides in 
little except its compressed contour and more distinctly bordered aperture. The lateral 
edges are either rounded or subangular. 
This variety occurs off Prince Edward Island, 50 to 150 fathoms; off Tahiti, 420 
fathoms, and 620 fathoms; north of Juan Fernandez, 1375 fathoms; and in the South 
Atlantic, mid-ocean, 1425 fathoms. 
The fossil specimens of Gaudryina chilostoma described by Reuss were from the Crag 
of Antwerp and the Septaria-clays of Germany. It is mentioned by Seguenza amongst 
the Foraminifera of the Upper Tertiaries of Calabria, and Hantken figures a very similar 
if not identical variety, which he names Gaudryina textilaroides (Mittheil. Jahrb. d. k. 
ung. geol. Anstalt, vol. iv. p. 15, pi. i. fig. 6), from the Middle Tertiaries of Hungary.

Under the name Gaudryina baccata are included certain wild-growing forms, which 
at first sight might be taken for monstrous examples of Gaudryina pupoides. They are 
characterised by distinct and generally much inflated segments, which are so combined 
as to produce a crooked or dislocated, or at least an irregular test. There is, however, a 
sort of method in the irregularity, very noticeable when a number of specimens are seen 
together, showing that it depends on something more than individual accident ; and the 
distribution of the specimens favours the idea that they represent a tolerably definite 
local variety. 
The occurrence of Gaudryina baccata has been recorded at seven points in the North 
Atlantic, at depths of 290 to 1750 fathoms ; at one in the South Atlantic, 1900 fathoms ; 
at two in the South Pacific, 210 and 2100 fathoms respectively ; and at one in the North 
Pacific, 2300 fathoms. 
The specimens originally described by Schwager were from the Pliocene deposits of 
Kar Nicobar, and similar examples are figured by Hantken from the Clavulina-szaboi 
beds of Hungary.
