FORAMINIFERA— HEllON-ALLEN AND F.ARLAND. 67 



grey, almost wliitc, hut as the Polar Continent is approached the colour darkens 

 owing to the increasing quantity of dark mineral constituent. The pale colour 

 was at first thought to be due to the presence of diatomaceous material, but the 

 examination ol ciushed specimens in l)alsam under a high power reveals an entire 

 absence of such material, the test 1)eing constructed entirely of most minute 

 mineral particles. 



Faure-Fremiet {iit supra) figures a form under the name of M. (theoUnifonnis, 

 Brady, which certainly has no resemblance to Brady's type, but may !)e related 

 to Chapman's, from which it differs in its cribrate aperture on a produced neck, 

 its comparatively coarsely agglutinate test, and the arrangement of the chambers, 

 which are on the M. bosciana or transverse plan, instead of the straight M. 

 ohlonga arrangement. The text-figure and description in his 1913 Paper {ut supra 

 p. 262, fig. 4), however, shows a much less coarsely agglutinate shell, and the 

 description brings the species into close agreement with our specimens, except 

 that we have not observed any specinrens with cril)rate apertures.

A single specimen, resembling d'(Jrbigny's original figuic. 



30. Miliolina pijfprtaea (l-ieuss).

Stations 5, 8, 10, 11. 1(3, 17, 22, 3(5 (+ R. d. J.). 



Frequent at a few Stations, rare at the others. The round milioline type pre- 

 dominates, but at Stations 10. 11 and 17 a compressed form occurs in its company 

 in about equal proportions. The specimens at Station 17, of both types, are 

 abnormally long and narrow. 



37. Miliolina seminulum (Linne).

 Miliolina seminulum, Heron-.Uleii and Earland, 1914, etc., FKA. 1915, p. 569, pi. xlii, lig. 31. 



Stations 2, 3, 5, (i, 17, 26, 30-32, 48 (+ Iv. I., H. d. J.). 



Never very abundant. In the N.Z. area the bulk of the specimens are of the 

 M. vulgaris (d'Orb.) type, but, in the Antarctic, d'Orbigny's type occurs only 

 at Station 31, in company with typical M. seminulum. The best N.Z. area is 

 Station 5. rhe best Antarctic Station 48, the only Station where it occurs with 

 any frequency.
