by Dr. A. Silvestri.* Some of the specimens met with here resemble that form, with 

 the exception that the orifice is both ecto- and ento-solenian in the same shell — ^that 

 is to say, the aperture is inverted, and then drawn out to form a tubular neck.

 area. 



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

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

 and off Aru Island, south-west of New Guinea, 800 fathoms (Brady) ; from the 

 Malay Archipelago (Millett) ; and from the Island of Delos, in the Mediterranean 

 (Sidebottom).

Our specimens are small and very diaphanous in appearance. 



Distribution. — Brady records this form (as L. quadricostulata) from two localities, 

 both in the Southern Hemisphere — viz., Balfour Bay, Kerguelen Island, 20 to 

 50 fathoms ; and off Sydney, 410 fathoms. Millett obtained it from the Malay 

 Archipelago. In the " Challenger " lists it is also recorded for the New Zealand 

 area (as L. quadricostulata). 



Present Occurrence. — Off the Snares ; 60 fathoms ; very rare. Ten miles north 

 of Enderby Island ; 85 fathoms ; rare. 



Lagena lagenoides, Williamson sp., var. nuda, var. nov. (Plate XV, fig. 9.) 



Our specimens generally resemble Williamson's fig. 26,t but the peripheral 

 flange, instead of being radiately striated, is quite plain and smooth. The eversion 

 of the neck terminal is very marked in the present examples.
