HENRY SIDEBOTTOM ON LAGENAE OF THE SOUTH-WEST PACIFIC. 197 







Onlv two specimens were found, each of them badly fractured. 

 Both have been utilised in preparing the illustration, which must 

 be considered as a drawing of a restored specimen. Locality; 

 Uncertain. 



Lagena bicarinata Terquem pp. (PI. 17, figs. 16, 17). 

 Fissurina bicarinata Terquem, 1882 7 p. 31, pl. 1 (9), fig. 24. 



The type-form does not appear to be present. 



PI. 17, fig. 16. The tests are in a very opaque condition. 

 Locality: Nos. 23, 24, 33, 34, 40. 



PI. 17, fig. 17. There are two or more spines at the base. 

 Eleven specimens are in good condition. Locality : Nos. 2-3. 



+ PI. 19, fig. 27. See remarks + p. 419. Locality ; Nos. 2-4. 



A few also occur, very similar to these, except that the body of 

 the test is more circular in outline. Locality : Uncertain. 



Lagena bicarinata Terquem sp. var. (PI. 17, fig. 18). 



Test bicarinate. The faces of the test are slightly convex, and 

 the two keels slope towards their edges, the effect being that the 

 test appears to have a boss on either face. Orifice much com- 

 pressed and composed of a row of pores. A solitary specimen. 

 Locality : No. 37. 



Lagena bicarinata Terquem sp. var. (PI. 17, fig. 19). 



Test bicarinate and apiculate, with a row of very short tubular 

 projections running round the edge of the test between the keels. 

 The test becomes more compressed as the orifice is approached. 

 Two examples only occur. The neck appears to be broken olT in 

 both cases. Locality: No. 43. 



Lagena bicarinata Terquem sp. var. (PI. 17, fig. 20). 



Test bicarinate, the keels generally dying away as they 

 approach the orifice, which is composed of a series of fine pores. 

 I cannot say if the fine bands, which adorn each face of the test, 

 a,re raised or not. Bands of different nature and length are 

 found on other species besides L. fasciata, so I prefer to place this 

 form under L. bicarinata, instead of treating it as L. fasciata in 

 the bicarinate condition. Locality : Nos. 1-10, 13, 15, 16.
