^82 HENRY SIDEBOITOM ON LAGENAE OF THE SOUTH-WEST PACIFIC. 



PL 14, figs. 17, 18. Entosolenian and ectosolenian variety of the 

 same, the apiculate process being a tube in all three cases, 

 Locality : Odd specimens from a few stations. 



There is a still larger specimen than fig. 17 with a longer pro- 

 jecting tube at the base, but it is not so globular in shape. There 

 -are also two fine apiculate, ovate specimens, one of which has a 

 few subsidiary spines at the base of the test. Specimens from 

 various stations occur similar to figs. 19, 20, the tube being long 

 and slender, the orifice round and placed a little to one side. 

 Some of the tests are asymmetrical like fig. 20, and a few are 

 broader in relation to their height than the two figured. 



Lagena apiculata Keuss var. nov. pnnctulata 

 (PI. 14, figs. 21-23). 



The contour of the test is subject to a good deal of variation ; 

 more generally the forms are like figs. 21, 23, but examples that 

 are asymmetrical in outline occur, see fig. 22. Round in section, 

 orifice usually fissurine, but sometimes with three radiating 

 fissures. The whole of the test is covered with large pores. 

 The entosolenian tube is straight and free. This handsome 

 foraminifer may be allied to Amphorma punctata Seguenza 

 (1862), pi. 1, fig. 39, and L. apiculata (Reuss) Terquem (1886), 

 pi. 1, fig. 5. Most of the tests are pointed at the base, but a 

 few are more or less rounded off. Locality : It is marked to 

 occur at six stations. Three were found at No, 9 and four at 

 No. 18. 



Lagena ovum Ehrenberg sp. 



Miliola ovum Ehrenberg, 1843, p. 166; 1854, pi. 23, fig. 2; 

 pi. 27, fig. 1 ; pi. 29, fig, 45. 



This is an unsatisfactory species. See remarks about fig. 14. 

 Besides odd specimens that may be brought under this heading, 

 there are a good number which may, or may not, be single 

 chambers of a Nodosaria. They have a short internal tube, and 

 a small ring at the base. Inside this ring the sliell seems to 

 be concave, has a granulated appearance, and may be porous. 

 Some of the specimens are comparatively large, and tend at 

 times to broaden out at the sides. Locality : Chiefly Nos, 19, 

 21, 29.
