large as the specimen referred to. Locality : No. 3, and either 

 No. 35 or 39. 



Besides the above, there are a few specimens which are much 

 smaller, especially in the width of the test. Locality : Nos. 17, 

 19, and one or two other stations. 



Lagena lagenoid.es Williamson sp. var. nov. duplicata 



(PI. 17, fig. 2). 



The test is bicarinate ; aperture oval and the keels tubulated. 

 Six specimens found. Locality : Nos. 24, 37.

Lagena tubulifera var. tenuistriata Brady, 1881, Quart. Joiirn. 



Micr. Sci. vol, 21 (N.S.), p. 61. 

 Lagena lagenoides Williamson var. tenuistrata Brady, 1884, p. 479, 



pi. 60, figs. 11, 15, 16. 



*P1. 19, fig. 4. Very frequent. These correspond to the 

 Challenger Report, pi. 60, fig. 11. The trifacial form also occurs. 

 Locality ; Nos. 1-11, 13, 14, 17, 21-24, 29, 31, 33-35, 37, 39-41. 



There is another set of specimens which are not quite so large 

 and have the costae on the body of the test, farther apart. 

 Locality : Nos. 14, 15, 17, 18. 



There are a few large specimens very similar to the Challenger 

 Report, pi. 60, fig. 15. In the stouter examples the fine costae 

 coalesce to such an extent that the surface has a pitted appear- 

 ance. Locality: Nos. 2, 8, 11, and one or two other stations. 



Lagena formosa Schwager (PI. 17, figs. 3-7). 



Lagena formosa (pars) Schwager, 1866, p. 206, pi. 4, fig. 19. 

 Lagena formosa (Schwager) Brady, 1884, p. 480, pi. 60, figs. 10, 

 18-20. 



This is present in many forms ; some show the raised border 

 punctate, others do not. See remarks **" p. 414. 



PI. 17, fig. 3. In this, which is obviously of the same kind as 

 fig. 18, pl. 60, in the Challenger Report, the raised border is 

 absent. Others agree with this figure, also with the Challenger 

 Report, fig. 20. 



Several very fine specimens are intermediate between fig. 18 

 and L. formosa var. favosa Brady, on the same plate, fig. 21.
