HENRY SIDEI30TT0M ON LAGENAE OF THE SOUTH-WEST PACIFIC. 395 



Lagena foveolata Reuss (PL 16, fig. 15). 



Lagena foveolata Reuss, 1862 (1863), p. 332, pi. 5, tig. 65. 

 Lagena No. 25 von Schlicht, 1870, p. 10, pi. 3, fig. 25. 



PI. 16, fig. 15. This is exceedingly delicate in its sculpture, 

 :and it is very likely the same as the one figured by Mr. Millett 

 in his Malay Report, 1901, pi. 1, fig. 15. His drawing is 

 much more satisfactory than mine. The test glistens. Three 

 fire marked on the Chart, but one of the three on the slide is 

 L. striata, so the exact locality of the other two becomes uncertain. 

 Locality : Nos. 1, 20, 26. 



Lagena foveolata Reuss var. (PI. 16, figs. 16, 17), 



This is an interesting variation. About thirty-five are on the 

 *<lide ; all are apiculate and nearly all are in perfect condition. 

 The cells are quite distinct and their bases show no sign of 

 perforation. Locality/ : Chiefly Nos. 17, 29, also very rarely at 

 various stations. 



Lagena foveolata Reuss var. nov. spinipes (PI. 16, 



figs. 18-21). 



In this variation some of the costae project at regular intervals 

 round the base and also carry very narrow, minute, blunt spines 

 as shown in the drawings. These spines appear to be tubular. 

 In some of the specimens they are absent, but probably they have 

 been broken off, as on a careful examination minute, loop-like 

 orifices can be detected. Many of the tests have so much 

 exogenous shell-grow^th filling up the cells that it is with diffi- 

 culty the cross-bars can be detected, but on breaking open such a 

 test, mounting it in Canada balsam, and viewing the inside 

 concave surface by transmitted light, the cross-bars show' quite 

 distinctly. 



PI. 16, figs. 18, 20 must be taken as being more or less 

 diagrammatic representations. I^ocality : Chiefly Nos. 9, 17, 19 

 and odd examples from a few other stations. 



PI. 16, fig. 21. A solitary specimen, evidently a rotund form. 



Lagena foveolata Reuss (?) var. nov. paradoxa (PI. 16, 



figs. 22, 23). 



The test is flask-shaped, always elongate, with a short neck, 

 slightly thickened at the orifice. Fine costae run down the test.
