THE VOYAGE OE H.M.S. CHALLENGED. 
a few exceedingly delicate longitudinal striae, chiefly near the primordial end of the test — 
very similar in all respects to the specimens represented by figs. 4 and 5. 
Examples of this sort have been found living at two localities, namely : — off Christmas 
Harbour, Kerguelen Island, 120 fathoms, and on the western shores of Patagonia. 245 
fathoms. 
The specimens referred to by Karrer were Tertiary fossils from the “ Mediterran-Stufe ” 
of Berchtoldsdorf, near Vienna.

There is no true specific distinction between Uvigerina aculeata, d’Orbigny, and 
Uvigerina asperula, Czjzek ; nevertheless it appears convenient to recognise both 
varieties, the one characterised by exostoses which take the form of stout spines or pointed 
perforated tubercles, either scattered over the whole test or over all except the very 
early chambers; the other rugose or hispid externally, the projecting points being 
minute and often arranged in lines. 
Whether in the recent or fossil condition, spinous Uvigerince are much less common 
than those with merely hispid exterior. Such forms, however, have been met with at one 
locality in the South Atlantic, east of Buenos Ayres, depth 1900 fathoms ; and at three 
in the South Pacific, namely, — north of Juan Fernandez, 1375 fathoms; off Ki Islands, 
580 fathoms ; and off Aru Island, 800 fathoms. 
The specimens on which the original description was based were Miocene fossils from 
Nussdorf near Vienna.

The Miocene fossils figured by Czjzek under the names Uvigerina asperula and 
Uvigerina orbigniana manifestly belong to the same species, and taken together the 
drawings represent very well the general characters of the hispid varieties of the genus. 
The outline of the test is ovate, varying as to relative length and breadth in different 
individuals ; the apertural end is furnished with a long tubular neck, and the opposite 
extremity is either rounded or terminates in a stout spine. The exterior of the shell is 
rough and hispid ; the minute aculei being either distributed indiscriminately over
