FORAMINIFEK A— HERON-ALLEN AND EARLAND. 123 



sented by («) short, comparatively few-chambered, stoutly-built individuals, and (6) a 

 very long, narrow, sharply angular type, ranging up to I'lOmm. in length, 

 characterized by an abnormally large number of gaudryine (triserial) chambers. 

 The two may possibly represent the megalo- and micro-spheric conditions. The 

 short form is found living sessile upon Polyzoa at Station 6.

 and one typical example from Station 13 (3,003 fms.).

Station 6. ■ 



Test free, multiform, the earlier portion consisting of closely-adherent triserial 

 chambers about seven in number, followed by two or three pairs of compressed 

 biserial chambers, with angular edges, the compressed portion sometimes having 

 a lateral twist. Constructed of large, flat sand-grains and ferruginous cement, very 

 dark brown at the initial portion of 'the shell, becommg brighter in colom* at the 

 oral extremity. Septation very obscure, especially in the earlier chambers. 

 Aperture, a normal loop on the inner face of the terminal chamber. 



Dimensions: — Length, •30--40mm. ; breadth, •20mm. 



This distinctive little forni is confined to Station 6, where a fair number of 

 specimens were observed. It cannot easily be mistaken for any other species, but 

 apparently belongs to the same group as G. wrightiana, Millett (M. 1898, etc., 

 FM. 1900, p. 10, pi. i, figs 11, 12) G. jonesiana, Wright (W. 1885-6, KH. p. 329, 

 pi. xxvii, figs 1, 2) and G. parimm, Guppy (G. 1894, FMDT. p. 651, pi. xli, 

 figs. 21, 22). Characterized by the small initial triserial development, and the 

 compressed biserial subsequent chambers. It bears some superficial resemblance 

 in the colour and rough construction of the shell to Verneuilina polystropha (Reuss). 

 but is readily distinguished by the compressed biserial chambers. The colour is 

 very distinctive.
