HENRY SIDEBOTTOM ON LAGENAE OF THE SOUTH-WEST PACIFIC. 183 



Lagena lucida Williamson sp. (PI. 16, rig. 9). 



K iitosolenia marginata var. lucida Williamson, 1848, p. 17, pi. 2, 

 fig. 17. 



There are nine examples which are nearly circular in outline., 

 and subcarinate. Locality : No. 44. 



PL 16, fig. 9. I believe this to be an elongate form of L. lucida, 

 in which the characteristic markings are only feebly represented. 

 The shell is very little compressed. Two or three specimens only 

 oocur. Locality : Uncertain. 



One or two tests are present which are intermediate between 

 the type and the elongate form referred to above. Several are 

 apiculate. Locality : Nos. 1, 6, 14, 21, 22, 24, 38, 42, 43. 



Lagena multicosta Karrer sp. 



Fissurina multicosta Karrer, 1877, p. 379, pi. 16 6, fig. 20. 

 Fissurina bouei Karrer, p. 378, pi. 16 6, fig. 19. 



The examples are small, and some are without the irregularity 

 of the costae characteristic of the type. Locality : Nos. 24, 29, 34, 

 35, 39, 42-44, and one or two of the earlier stations. 



Lagena fasciata Egger sp. (PI. 16, figs. 10-13). 

 Oolina fasciata Egger, 1857, p. 270, pi. 5, figs. 12-15. 



PI. 16, fig. 10. Beautiful specimens occur which have the mouth 

 protruding, and the orifice composed of a line of pores. The 

 bands are flush or nearly so. Large and small tests are on the 

 slide. Locality: Nos. 1, 3-5, 7, 10, 22, 44, and several other 

 stations which are uncertain. 



PI. 16, fig. 11. An apiculate form w r hich is extremely rare. 

 The edge of the test is flattened, and has a very fine groove 

 running down its centre. The orifice appears to be composed of a 

 line of pores. Locality : Uncertain. 



PI. 16, fig. 12. Slightly apiculate, the orifice large, and the 

 entosolenian tube divided at the end. The edges of the bands, 

 which are not interrupted at the base, appear to be somewhat 

 raised. When the test is opaque it is difficult to make out the 

 bands. Locality : Nos. 24, 34, 36, 43, 44 : frequent at No. 44. 



PI. 16, fig. 13. The test is apiculate and the opaque bands 

 which appear to be flush with the surface are continuous that is,.
