POEAMINIFEEA OY THE KEEIBIBA AECHIPELAGO. 629 



universally distributed. It occurs in the greatest abundance and in its best development 

 at Stn. 1, and very fine examples were also obtained at Stn. 9. At Stns. 3 and 10 

 the specimens were less characteristic and showed a tendency to pass, by inflation 

 of the chambers, into T. hauerii. 



The affinities of our species are between T. luculenta Brady and T. hauerii or gramen 

 d'Orbigny. It may be compared as regards its highly compressed and parallel-faced 

 test with the Textularia immensa of Cushmau (Proc. U.S. Nat. Mus. vol. xliv. 

 1913, p. 633, pi. Ixxix. fig. 2), from which it differs only in the character of its 

 aperture. 



We have specimens from Timor Sea (Java, 50 fms.), where it is frequent, and from 

 Vavau (S. Pacific, 16 fms.). We have also observed specimens in some of Brady's 

 unsorted material from Fiji at Cambridge, and a single specimen among his specimens 

 of T. agglutinans from " Coral Eeef, Australia, 17 fms." It is probably therefore 

 widely distributed in coral-reef areas.

Universally distributed and generally abundant. An excellent series of specimens 

 was obtained at many Stns., notably at Stns. 2 and 6. At Stn. 8 specimens intermediate 

 with T. gramen and at Stn. 11 specimens passing into T. trochus d'Orbigny were 

 observed. At Stn. 12 a monstrous individual, in which the normal shell was followed 

 by a cylindrical bigenerine series of three chambers set at an angle of 45° to the 

 principal axis of the shell, was found.

1 Station. 



At Stn. 11 a considerable number of specimens referable to this species, but 

 presenting extraordinary limbate or jugose characteristics extending all round the 

 shell, were found. We figure some of them. Like all the Textulariidse at this Stn. 

 the shells are largely constructed of minute rounded calcareous particles giving a very 

 striking appearance to the test, their glassy appearance contrasting very strongly with 

 the ochreous agoiutinating cement.
