The test of Pullenia quinqueloba differs from that of the typical Pullenia sphceroides 
in its larger dimensions and its more or less flattened contour. In general conformation 
it is nautiloid and biconvex, with the peripheral edge obtuse or rounded ; and the final 
convolution, which consists normally of five segments (rarely four or six) entirely conceals 
the preceding whorls. Externally the segments are slightly inflated, and the sutural 
lines correspondingly depressed. The shell sometimes attains a diameter of -^§-th inch 
(0*72 mm.). 
The specimens of this species dredged off Prince Edward Island, at which locality it 
is exceedingly abundant, displayed a remarkable variety of tint when first taken out of 
fluid. This appearance was occasioned by the high colour of the animal inhabiting the 
shell, which in some cases was of olive-green hue, in others yellow, and in others pink. 
Pullenia quinqueloba has nearly the same wide geographical and bathymetrical 
distribution as Pullenia sphceroides, but it appears to attain its best development in the 
southern hemisphere. Like the typical species, it is known only from bottom-specimens, 
and there is no reason to suppose that it ever lives at the surface of the ocean. It has 
been found as far north as lat. 62° 6' N. in the North Atlantic, and southwards to the 
Antarctic Ice-barrier, lat. 64° 18' S., and its range of depth extends from 20 or 30 
fathoms to 2750 fathoms. It is common in the “ warm area” of the Faroe Channel, and 
occurs sparingly on the shores of Great Britain and Belgium, in the Mediterranean and the 
Red Sea. Notes have been kept of its occurrence at nineteen Stations in the North 
Atlantic, at six in the South Atlantic, at five in the Southern Ocean, at fifteen in the 
South Pacific, and at two in the North Pacific. 
As a fossil it has been noticed in the Chalk of the north of Ireland (Wright), and 
of the Island of Riigen (Marsson) ; in the Barton Beds of the Isle of Wight (Brady), 
in the Septaria-clays of Germany (Reuss, Bornemann), in the Miocene deposits of the 
Vienna Basin (Reuss) and the Banat (Karrer) ; in the Salzthon of Wieliczka, and in the 
Crag of Antwerp (Reuss), and in the Upper Tertiaries of Southern Italy (Seguenza).
