424: HENRY SIDEBOTTOM ON LAGENAE OF THE SOUTH-WEST PACIFIC, 



At the base there is an oval flange, which projects more espe- 

 cially at the sides. This is a provisional description of the 

 form, as the specimen may be in an imperfect condition. It 

 is the best example on the slide. Locality : Six are marked as- 

 being found at No. 11. 



, Lagena alveolata Brady (PI. 21, figs. 1, 2).

PI. 21, fig. 1. The tests vary a good deal in outline, but the- 

 majority are pyriform. The two lateral carinae, which unite 

 with the median to form the loops at the base, are rough, or 

 striated, and frequently drawn together so that the openings are 

 nearly closed. The tube is straight. Locality : Chiefly No. 32- 

 It occurs rarely at a good many stations. 



PI. 21, fig. 2. There are three fine specimens which are only 

 very slightly compressed, and the division between the loops on 

 each face of the test is very small. 



PI. 21, fig. 26 shows the base, its divisions being filled with 

 granular matter. I think it probable that the walls at the base 

 are partially broken down. Locality : Uncertain. 



Lagena alveolata Brady var. nov. carinata (PI. 21, fig. 3). 



This differs from the type in that the test is carinate. One 

 example is in the trifacial condition. Locality : Chiefly Nos. 6, 

 7, 18.

 Lagena alveolata var. substriata Brady, 1884, p. 488, pi. 60, fig. 34. 



Two only occur. Locality : Nos. 30, 34. 



Lagena alveolata Brady var. caudigera Brady (PI. 21, fig. 4). 



Lagena alveolata var. caudigera Brady, 1884, p. 488, pi. 60, 

 fig. 25. 



Although the specimen shows signs of wear in the region of 

 the loops, I think there is no doubt that it is rightly placed under 

 this heading. One only found. Locality : No. 29.
