THE YOYAGE OF H.M.S. CHALLENGER. 
Uvigerina interrujpta, H. B. Brady (PL LXXY. figs. 12-14). 
Uvigerina interrupta, Erady, 1879, Quart. Journ. Micr. Sci., vol. xix., 1ST. S., p. 60, pi. viii. 
figs. 17, 18. 
Test much elongated, subspiral ; composed of a number of inflated or subglobose 
segments of gradually increasing size, arranged around a long axis. Earlier segments 
combined so as to form a more or less compact spire ; later segments disposed in an 
irregular, interrupted, alternating series, terminating in a tubular neck. Surface hispid 
or aculeate. Length, -g^th inch (0‘5 mm.). 
This variety bears very much the same relation to Uvigerina asperula that Uvigerina 
porrecta bears to the typical Uvigerina pygmcea ; that is to say, it is an emaciated form, 
of which the extension in length is out of proportion to the number of chambers produced, 
and the continuity of the spiral series is more or less interrupted thereby. 
Uvigerina interrupta has only been observed in dredgings from the South Pacific at 
the following points : — west coast of New Zealand, 1 50 fathoms ; off Kandavu, Fiji, 210 
fathoms and 255 fathoms ; off Raine Island, Torres Strait, 155 fathoms ; Humboldt Bay, 
Papua, 37 fathoms; and north of Juan Fernandez, 1375 fathoms. 
Sagrina (d’Orbigny), Parker and Jones. 
Sagrina 1 (d’Orbigny, 1839), emend. Parker and Jones [1865], Carpenter, Brady, Biitschli. 
Sagraina, Reuss [1861], Zittel, Scliwager, Marsson. 
Dimorpliina, Sc'h wager [1866], Hantken. 
Siphogenerina, Schlumberger [1883], 
The generic term Sagrina was introduced by d’Orbigny for a biserial or Textulariform 
variety of Uvigerina with longitudinal costas f and the author subsequently assigned to 
the same genus a rough dimorphous Textularian, differing only from Gaudryina in 
possessing a terminal aperture. 3 Further investigation has shown that there is no direct 
relationship between these two species, and that in point of fact no new generic name 
was required for either. Under these circumstances it would have been well to have 
allowed the name to lapse ; but it has been revived by Parker and J ones, and applied by 
them to a group of dimorphous Uvigerince, usually biserial in the arrangement of their 
early segments and Nodosariform in their later growth, and it is to this particular set of 
forms that the genus is now restricted. 
The test of Sagrina presents every variety of contour, from the elongate oval of some 
of the typical Uvigerince to the cylindrical or moniliform shapes of the Nodosarice. In 
1 The term Sagrina is retained as originally written. Changes in spelling such as that introduced by Reuss only tend 
to confuse the nomenclature, and require stronger justification than can be adduced in the present case.
