412 HENRY SIDEBOTTOM ON LAGENAE OF THE SOUTH-WEST PACIFIC 



PI. 18, fig. 22. This is the same as the one figured by Mr. 

 Millett, 1901, p. 623, pi. 14, fig. 8, of which there are numerous- 

 examples. Mixed up with them is a rather smaller form, the 

 wing of which is not so broad, but stouter, and therefore not so 

 liable to become damaged. There is one specimen in the trigonal 

 condition, found at No. 11. Locality : Chiefly Nos. 8, 11, 19, 22. 



PI. 18, fig. 23. The keel, in this instance, splits half-way down 

 the edge of the test and the space is filled with shell-growth or 

 debris, from which in a few instances fine, hair-like spines project. 

 This shell-growth, or debris, is not always confined to the split 

 carina, but often spreads over the lower half of the test, and the 

 delicate spines also appear. I presume that if the specimens 

 were in perfect condition these spines would be very numerous. 

 Tube attached. Locality : Chiefly Nos. 1, 21, 29. 



PI. 18, fig. 24. It may be that the carina has partially broken 

 away, leaving the tubular portion intact. There are only two ia 

 this condition, the one not figured showing even less of the carina. 

 The eutosolenian tube is short and straight. L^ocality : Nos. 

 11, 19. 



PI. 18, fig. 25. The cellular carina is narrow, but compara- 

 tively stout, and is absent for a short distance on each side of the 

 test. The internal tube is short and straight. Twenty-one 

 are on the slide. J^ocality : Chiefly at No. 11. Yery rare at 

 Nos. 8, 12, 19. 



PI. 18, fig. 26. The test is curiously contorted, especially the 

 lower half of the carina, one side of which dips down suddenly at 

 the base, thus causing the lower halves of the carina to lie in 

 diflerent planes. The keel itself seems inclined to be concave or 

 convex, according as the edge is twisted upwards or downwards. 

 It is a very delicate foraminifer and many of the specimens are 

 fractured. The tube is attached. Seventeen occur. Locality ; 

 Chiefly Nos. 11, 19. 



PI. 18, fig. 27. There are five examples of this circular and 

 entosolenian variety. The tube is curled back upon itself. The 

 test is fairly well compressed. fjocality : Four were found at 

 No. 19. 



On the same square are also five elongate specimens, but 

 the cellular rim is of a diflTerent character and the internal tube 

 is long and straight. iThe outline is that of an elongate 

 L. laevigata.
