Articulina Sagra d’Orbigny. 
Artieulina Sagra d’Orbigny, 1839, Foram. Cuba, p. 183, pi. ix. 
figs. 23-26. A. Sagra (d’Orb.) Brady, 1884, Chall. Kept., p. 184, 
pi. xii. figs. 22-24. 
None of the Malay specimens have the extreme development of 
the Vertebralina mucronata of d’Orbigny,* nor of the A. Sagra as 
figured by Brady, but they form a series extending from the Cuba 
specimens of the latter form to the A. lineata of Brady ; the decora- 
tion varying from costate to striate. 
It is pretty evenly distributed, although not common. 
Articulina lineata Brady. 
Articulina lineata Brady, 1884, Chall. Bept., p. 183, pi. xii. 
figs. 19-21. 
As before stated, this variety is connected with A. Sagra , and it 
would perhaps be better to include it in that species. None of the 
Malay specimens however have the margin “ thin and sharp,” as have 
some of the ‘ Challenger ’ examples. 
It occurs at the same Stations as A. Sagra , and is rather more 
abundant. 
It has been found at four 4 Challenger ’ Stations, one of which 
is Kaine Island, Torres Strait. There seems to be no other record 
of its occurrence. 
Articulina lineata Brady, smooth variety, plate Nil. fig. 8. 
This form occurs in company with A. lineata , and is rather more 
abundant. In differs only in the absence of the striations. Length 
0*50 mm. 
Articulina conico-articulata Batscli sp., plate XII. figs. 9, 10.

(Batsch) Brady, Parker, and Jones, 1888, Trans. Zool. Soc., vol. xii.

k. k. Geol. Keichs., vol. xxxviii. p. 694, pi. xiii. fig. 62. A. conico- 
articulata (Batsch) Egger, 1893, Abhandl. k. bayer. Akad. Wiss., 
Cl. II., vol. xviii. p. 224, pi. iii. fig. 2. A. extensa Egger, 1893, 
ibid., p. 242, pi. iii. fig. 3. 
It is unfortunate that the figure of this species given by Batsch 
should have been taken from a specimen in which the initial chambers 
are wanting, seeing that this cylindrical Articulina is found in two 
distinct forms. In one of these the earlier chambers are arranged on
