This species is very abundant and occurs in various forms, some 
with the surface smooth, others covered with papillae arranged in 
irregular curved lines, as shown in the figure, which is taken from 
one of the most aberrant forms of the species, the earlier chambers 
being large in proportion, and unusually angular and protruding. 
It occurs at Stations in both areas, hut mostly in Area 2. 
Massilina secans var. macilenta Brady, plate XIII. fig. 4. 
Miliolina macilenta Brady, 1884, Chall. Kept., p. 167, pi. vii. 
figs. 5, 6. 
The Malay specimens confirm Brady’s suspicion that this is hut 
a costate variety of M. secans , and it is scarcely possible to separate 
the two forms. 
M. macilenta is more widely diffused than the type, but occurs 
in less abundance. 
The ‘ Challenger ’ Stations are Hares Harbour, Admiralty Islands ; 
Humboldt Bay, Papua ; and off Honolulu, Sandwich Islands. 
There appears to be no other record of its occurrence. 
Massilina alveoliniformis sp. n., plate XIII. figs. 5, 6, 7. 
Test elliptical, chambers tubular, the earlier ones arranged irre- 
gularly around the long axis, the later ones in a Spiroloculine series, 
periphery rounded, aperture terminal, radiate or cribrate, obscured by 
sand-grains. Texture arenaceous. Length 1 -40 mm. 
This species in some respects resembles Sigmoilina tenuis, but 
differs from it in the composition of the test and the character of the 
aperture. It may be regarded as a dimorphous form of Miliolina 
cilveoliniformis , the earlier chambers, as shown by fig. 6, having ail 
the characters of that species. Quinqueloculina fabularoides Karrer * 
has a similar aperture, and the arrangement of the chambers is not 
unlike. 
It has been observed at Stations 2, 13, and 22, but the specimens 
are not numerous. 
Hauer ina d’Orbigny. 
As represented by the Malay specimens, this genus has the earlier 
chambers arranged after the fashion of Miliolina alveoliniformis. 
These are succeeded by a series on the Spiroloculine plan, and these 
again by the arrangement characteristic of the genus, in which there 
are three or more segments in each convolution. The aperture is 
invariably much compressed, hut is not always cribrate.
