HENRY SIDEBOTTOM ON LAGENAE OF THE SOUTH-WEST PACIFIC. 393 



forms are on the same square and so the separate localities 

 cannot be given. Locality : Thirty-seven at No. 19. Frequent 

 at Nos. 21, 22, and a few other stations. 



PI. 16, lig. 9. Very rare. Locality : No. 20 and several 

 others. 



PI. 16, fig. 10 is an exceedingly finely marked variety. The 

 lines of pores lie very close together, and I cannot make out 

 whether they are on a ledge or not. It may be L. feildeniana, but 

 I have decided to place it here, on account of the bent neck so 

 often characteristic of L. striatopimctata. It is very rare. 

 Locality : Two at No. 19, and odd specimens at one or two other 

 stations. 



Lagena striatopunctata Parker and Jones (?) var. nov. 



complexa (PI. 16, fig. 11). 



This elegant variety has the surface of the costae hollowed out 

 and the spaces between them roughened by granular shell- 

 growth ; showing through this are two or three lines of de- 

 tached, minute tubercles, running lengthwise down the test. The 

 shell-growth does not appear in the drawing, as I wished the 

 tubercles to appear plainly. There is a tendency in this variety 

 to disintegrate, and when this has happened a complete shell -wall 

 is revealed, with many spines attached to it. There is one 

 perfect specimen, and another nearly so. One, which I believe 

 to be the same variety, has only the inner shell left, with many 

 spines and bits of costae. It is just possible that this is a com- 

 pound-walled Lagena, and therefore I have put a query against 

 it. There are several other Lagenae on the square that do not 

 belong to the same species, and so the exact locality cannot b e 

 given. 



Lagena striatopunctata Parker and Jones var. nov. inaequalis 



(PI. 16, fig. 12). 



This is a handsome variety. The test near the base is round, 

 or nearly so, in section, but gradually becomes compressed as it 

 approaches the orifice, which is fissurine. From each side of the 

 orifice springs a keel, thickened at the edge, which dies away a 

 short distance down the test. Between the punctate costae there 

 is a very fine short and slightly raised plain costa, which varies in
