HENRY S1DEB0TT0M ON LAGENAE OF THE SOUTH-WEST PACIFIC. 185 



Lagena staphyllearia Schwager sp. 

 Fissurirta staphyllearia Schwager, 1866, p. 209, pi. 5, fig. 24. 



The non-carinate form is rare. The number of spines varies. 

 The tube is attached to one side, thus causing the orifice to be 

 eccentric. In a few instances of the carinate variety, where only- 

 two spines are present, it is impossible to separate them from the 

 Fissurina bicaudata Seguenza, which is generally placed with L. 

 man/biota. Locality Nos. 1-7, 9-12, 15-25, 29, 33, 34, 36, 37, 

 39-43. 



The variety with either the ketl or the lower part of the test 

 serrated or partially fimbriated is not so frequent, but occurs at 

 many localities. The orifice is central and the sides of the test 

 are only slightly carinate. Locality : Nos. 5-8, 10, 11, 14, 15, 18, 

 19, 21, 22, 24, 33, 34, 40, 43. 



+ P1. 17. fig. 19. Very rave. Locality : Nos. 2, 3, 15, 22. 



+ P1. 17, fig. 21. This peculiar variety is rather rare. The 

 tests are semi-opaque. There is a short entosolenian tube. 

 Locality : Nos. 5-11, 13, 21, 23, 25, 36, 39, 40.
