Verneuihna variabilis, n. sp. (PI. XLVII. figs. 21-24). 
Typical form, fig. 23 a. b. — Test free, triquetrous ; oblong, broadest near the oral end, 
and tapering somewhat towards the aboral extremity ; compressed and concave on 
three sides, the three salient edges thin and slightly rounded ; margins tabulated, incised, 
or irregular. Segments numerous, irregularly triserial ; septation often obscure. Aperture 
an elongate fissure at the margin of the final segment, generally nearly central. Texture 
coarsely arenaceous, exterior rough. Length, -|th inch (3 mm.). 
The above description conveys the characters of what may be regarded as the typical 
condition of this polymorphic species,— that in which its affinity to Verneuilina triquetra 
and other allied forms is most clearly recognised. Of the numberless modifications of the 
typical structure, the most common are such as those represented by fig. 24, in 
which the test is more or less quadrate, and by figs. 21 and 22, in which it loses 
to some extent its ternate character in the other direction, and presents during part 
of its growth only two marginal edges. No specific or even varietal distinction can be 
drawn between these forms ; and in the locality whence the specimens were obtained, 
every intermediate condition is common. 
Dr. Sch wager has proposed a distinct genus, Reussia, for the varieties of Verneuilina 
which have the slit-like aperture noticed in the present species, not having perceived, 
pparently, how little it differs in reality from the ordinary Textularian orifice. 
Verneuilina variabilis is found associated with Verneuilina triquetra in the coral-sands 
of Kandavu, Fiji Islands, at a depth of 210 fathoms. 
Verneuilina pygmcea, Egger, sp. (PI. XLVII. figs. 4-7). 
Bulimina pygmcea, Egger, 1857, Neues Jalirb. fur Min., &c., p. 284, pi. xii. fig=. 10, 11. 
Verneuilina pygmcea, Parker and Jones, 1863, Ann and Mag. Nat. Hist., ser. 3, vol. xi. pp. 92, 98.

pi. xv. fig. 10. 
It is probable that Parker and Jones are right in referring the Bulimina pygmcea of 
Egger to the genus Verneuilina ; and if so, the specimens portrayed in PI. XLVII. figs. 
4-6, must be assigned to that species. Nevertheless it would have been more satisfactory 
had the author, either in his description or in the drawings accompanying it, indicated 
with greater clearness the minute characters of the shell, and especially of its aperture. 
The test of Verneuilina pygmcea differs from that of Verneuilina polystropha in the 
compact and very finely arenaceous texture of the walls, its nearly white colour, and 
smooth exterior ; and in the aperture, which is an elongate, arched fissure bordered by a 
raised lip. 
Under the name Verneuilina rotundcita, Dr. Ivarrer has figured a shell with similar 
general features, which probably belongs to the same species (Drasehe’s “ Insel Luzon," 
p. 85, pi. v. fig. 2).
