fiENRY SIDEBOTTOM ON LAGENAE OF THE SOUTH-WEST PACIFIC. 401 



Entosolenian tube straight. Orifice oval. A few have the base 

 rounded off, but others are more or less pointed. Locality : No. 17 

 and various other stations. 



Lagena acuta Reuss sp. (PL 17, fig. 9). 



Fwsurina acuta Reuss, 1862, p. 340, pi. 7, fig. 90. 

 F. apiculaia, p. 339, pi. 6, fig. 85. 



Again one has to deal with a great variation in form. Elon- 

 gate examples like fig. 9 are very rare, and they are very slightly 

 compressed. These correspond to the F. apiculata of Reuss. 

 Small examples which are ovate, or pyriform, in outline, are 

 common. These latter generally have the apiculate process very 

 small. Locality : Various. 



Lagena acuta Reuss sp. var. nov. virgulata (PI. 17, fig. 10). 



The form is that of Fissarina apiculata Reuss, 1862, p. 6, 

 fig. 85, and has the four curious markings, two on either face, 

 referred to before under L. laevigata var. The body of the test 

 becomes more compressed as it approaches the orifice, w^hich is 

 fissurine and almost closed. Locality : It occurs at a good many 

 stations. Five are marked on the Chart as being found at No. 29. 



Lagena acuta Reuss sp. var. (PI. 17, fig. 11). 



I think this may be treated as a variety of L. acuta. The test 

 is only slightly compressed, and when viewed endways, looking 

 down on the orifice, it has rather a square appearance, caused no 

 doubt by the three lines of perforations being situated at the 

 four corners, so to speak. A few^ have the base rounded, but 

 the others are more or less pointed. The tube is short and 

 i^traight. I cannot make out the exact nature of the orifice. 

 It is very minute and seems to be circular. As a rule, the 

 perforations are confined to three lines. Nineteen found. 

 Locality : Nos. 1, 7, 14, and a few others. 



Lagena lucida Williamson sp. (PI. 17, figs. 12-14). 



Entosolenia marginata var. hicida Williamson, 1848, p. 17, pi. 2, 

 fig. 17. 



This pretty little foraminifer is found at a few stations, but 

 is always very rare, though typical. PI. 17, fig. 12, represents
