420 HENRY SIDEBOTTOM ON LAGENAE OF THE SOUTfl-WSSrlr PACIFIC. 



growth, from which project innumerable fine sphies: Licality : 

 No. 19. 



On the same square are several very similar specimens, but the 

 double carina is confined to the body of ' the-^test,'' there are no 

 spines showing, and the keels are not placed so far apart. 



Lagena auriculata Brady (PI.' 20; figs: 4-14). 



Lageiia auriculaUi Brady, I'^^'^l QudH. Journ,' Micr. Sci, vol. 21, 



N.S., p. 61. 

 Lagena auriculata Brady, l$84,^p. 487, pi. GOj figs. 29, 33 and 31 (?). 



In these soundings this ^species is subject to extraordinary 

 Variation. Tlie 'specitri'eils form a most interesting series, eight 

 <jf which resemble Brady's CAaZ^e/i^e/* illustration, pi. 60, fig. 33. 

 Ilocality : No. 2^. 



Pi. 20, fig. 4. This is the same as' the above, excepting that 

 there is a flange projecting at the base, on both sides of the 

 tfest. Locality : No. 19. Only one occurs. 



PI. 20, fig. 5. In this the body is elongate, with a long neck, 

 and the loop-shaped, laminar process on either side of the base is 

 l^ngth'ened and narrowed, until it becomes more of a tube than 

 is tho case with 'the type form. Only three or four occur, and in 

 one or two of tb^^m ' the tubular extensions are rather wider than 

 in the one figurfed. Tlie tests are compressed. Locality: Two 

 occur at No. 9. 



PI. 20, fig. 6. Tliiis> is very similar to the one figured by Mr. 

 Millett, in his MalayvReport, 1901, PI. 14, fig. 15. Rather rare. 

 Locality : These speeitaens are mixed with those of other species 

 and so the exact localitiy is> uncertain. 



PI. 20, figs. 7, 8. These^ are similar to the Challenger figure, 

 pi. 60, fig. 29. The examples vary both in size and in the amount 

 of compression of the basal extensions. The internal tube is 

 straight. About thirty-eight occur. Locality : Nos. 3, 13, 26, 

 and many others. 



PI. 20, figs. 9, 10 (round in section). As some of the well- 

 known Lagenae, which are typically round in section, have also 

 their compressed form, so one would expect that some of those 

 which are typically compressed would be occasionally represented 

 by specimens which are round in section. Such is the case with 

 these. The tube is free and much twisted. Locality : It occurs 

 at thirteen stations, but chiefly at Nos. 1, 23. Always rare.
