Presenting great variation, both in length of neck, development of the basal 

 cup, rotundity and compression, smoothness and .striation, and coarseness of 

 sulcae. The best at Station 36, where practically every development occurs.

Stations 11, 36 (+ T. d. F.). 



Two very fine and typical specimens of the round form at Station 36. At 

 Station 1 1 , two specimens of the compressed form ; at this Station it occurs in 

 company with our new var. L. danica var. pendulum., to which it bears consider- 

 able resemblance, but difters in the character of the aperture. Sidebottom's 

 variety has a short, thick neck tapering into the body of the shell, whereas 

 L. danica var. pendidwii has a thin neck attached to a globular body, with a 

 thm flange running from the top of the neck to the widest part of the shell. 



306. Lagena stelligera, var. nelsoni, nov. PI. Y. figs. 20-22. 



Stations 27, 45, 47, 48, 53. 



Test, an irregular compressed oval, with prominent Itasal ring extending to. and 

 enclosing, a considerable area. At the oral end, and set to one side of the 

 middle axis of the shell, a solid bead of shell-substance projects like a beak and 

 includes the aperture, from which a very long and curving entosolenian tube 

 extends backwards and then downwards almost to the base of the shell. Shell- 

 wall in living specimens extremely glassv and transparent, becoming opalescent 

 in dead shells. The mass of orange-yellow protoplasm is large and often occupies, 

 in the dried state, about a third of the internal cavity. 



Dimensions :— Length, •20--35 mm., breadtli. •18--32mm. 



This is a very distinctive and excentric type, occurring at several of the 

 Antarctic Stations, usually one or two specimens at each, but more aliundantly
