HENRY SIDEBOTTOM ON LA.GENAE OF THE SOUTH-WEST PACIFIC. 421 



PI. 20, fig. 11. There are Only two or three of this minute form. 

 The tube is attached and the test well compressed. Locality : 

 Exact locality uncertain. 



PI. 20, fig. 12. In these the tubular processes at the base are 

 comparatively long. The entosolenian tube is long, more or less 

 attached, and curled back after nearing the base of the test. 

 Aperture compressed. About thirty are on the slide. Locality: 

 Chiefly at No. 1. Rare at Nos. 3, 9, 14, 25. 



At No. 11 nine occur of the same outline, but the tubular pro - 

 <;esses only just project and the internal tube is much shorter. 



PI. 20, figs. 13, U. Mr. Millett in his Malay Report,' 1901, 

 pi. 14, figs. 14, 16, only figures the contorted and trifacial form of 

 this beautiful variety of L. auriculata. Fig. 13 represents the 

 variety in its normal condition and there are forty-seven on the 

 slide. Locality: Chiefly Nos. 1, 11, 19, 21. Fig. 14 is the con- 

 torted form. None of the examples show the " auricular " portion 

 carried so far up towards the neck as is represented in Mr. Millett's 

 figure. Locality : Chiefly Nos. 1, 11, 19, 21. Thirty occur. 



Lagena auriculata Brady var. (PI. 20, figs. 15-18). 



PI. 20, fig. 15. The test is generally slightly roughened and 

 the tube is attached. The body of the test is circular, or ovate, 

 and compressed. The drawing is taken from the largest of the 

 specimens. Several of the smallest have the orifice opening for- 

 wards. Locality : Chiefly at No. 32, and rarely at several other 

 stations. 



PI. 20, fig. 16. A solitary specimen, in which the outline of 

 the carina is nearly square. Locality : Station uncertain. 



PI. 20, fig. 17. There are several examples in which the carina 

 stops short of the tubular processes, or only just reaches them. 



PI. 20, fig. 18. In these the carina is confined to the base of 

 the test and the entosolenian tube is of extraordinary length. 

 Locality : Chiefly No. 19. Very rare. 



Lagena auriculata Brady var. nov. arcuata (PI. 20, 



figs. 19, 20. 



The costae at the lower end of the test form a series of tall 

 arches. In one or two instances the base between the tubular 

 projections is armed with a long spine. The examples are small,
