 Journ. R. Micr. Soc, p. 619, pi. xiv, fig. 1. 



Distribution. — Brady records this variety from the South Atlantic and the 

 Southern Ocean, and Millett from the Malay Archipelago. In the " Challenger " 

 lists it is included in the New Zealand area. The fossil examples came from the 

 Tertiary clays of Pietzpuhl. 



Present Occurrence. — Off the Snares ; 60 fathoms ; frequent. Twenty miles 

 north of Auckland Island ; 85 fathoms ; rare. Ten miles north of Enderby Island ; 

 85 fathoms ; common. 



Lagena schlichti, A. Silvestri sp. (Plate XV, figs. 7 a, h.) 



Fissurina schlichti, A. Silvestri, 1902, Mem. d. Pont. Ace. Rom. d. Nuovi 

 Lincei, vol. xix, p. 14 ; woodcuts, figs. 9-11. 



This species is often confused with L. marginata, W. & B. It has a distinctive 

 eccentric aperture and a long entosolenian tube. Our specimens differ from 

 Silvestri's Mediterranean form in having the margin entire, instead of denticulate, 

 aborally.

 the Snares ; 60 fathoms ; frequent. Twenty miles north of Aiickland Island ; 

 85 fathoms ; frequent. Ten miles north of Enderby Island ; 85 fathoms ; common.

The majority of our specimens resemble Brady's fig. 25. The example figured 



by Brady under the same name (fig. 24) has been erected into a new species {L. bradii)
