REPORT ON THE FORAMIKLFERA . 
359 
The average size of recent specimens somewhat esceeds that of the fossils, adult shells 
being seldom less than 1 mm. in length, and occasionally 1 ‘2 mm., or even more. 
Textularia quadrilatera has been observed at two Stations in the North Atlantic: 
— off G-omera, Canaries, 620 fathoms; and off St. Vincent, Cape de Verde Islands, 1070 
fathoms; and atone in the South Atlantic, — south-east of Pernambuco, 350 fathoms. 
In the South Pacific it is more plentiful, having been found at eight localities, ranging 
in depth (with one exception) between 410 and 1350 fathoms. The finest examples 
were obtained off Tahiti, 420 fathoms. 
The only recorded fossil specimens are those described by Dr. Schwager from the 
Pliocene of Kar Nicobar. 
Textularia crispata, n. sp. (PI. CXI II. fig. 2, a.b.). 
Test free ; elongate, tapering, complanate, always more or less twisted in contour ; 
lateral faces flattened, peripheral edges square. Segments numerous, nine to twelve in 
each series, the marginal ends angular and projecting ; sutures distinct, often slightly 
limbate. Walls thin, calcareous, or very finely arenaceous ; colour white to light brown. 
Length, ^Th inch (0'84 mm.). 
This is an exceedingly striking species, resembling Textularia concava and Textularia 
quadrilatera in its complanate form and square edges, but easily recognised by the 
twisted contour and the dentate lateral margins of the test. 
Textularia crispata has only been found at a single locality, Station 185, off Raine 
Island, Torres Strait, 155 fathoms, where it is tolerably common. 
Textularia transversaria, n. sp. (PI. CXIII. figs. 3- 5) 
Test free ; complanate, elongate, tapering ; oral end broad and truncate, aboral 
extremity obtusely pointed or slightly rounded ; lateral edges thin and irregular, or 
square. Segments numerous, ten to fourteen in each row, narrow ; arranged transversely 
to the axis of the test ; peripheral ends generally fistulose. Length, about -g^th inch 
(0'5 mm.). 
It is possible that this may be only a fistulose variety of Textularia pectinata, Reuss 
(Denkschr. d. k. Ak. Wiss., vol. i. p. 381, pi. xlix. figs. 2, 3. — Sitzungsb. d. k. Ak. Wiss., 
vol. lv. p. 98, pi. iii. fig. 11), but in the absence of recent specimens exhibiting satisfac- 
torily the normal characters of that species, there is nothing to indicate with certainty 
that such is the case. 
The fistulose condition of the Textularian test is a subject of some interest, but will 
be better treated in connection with Textularia siphonifera and Textularia sagittula ,
