Fig. 1. Auloceros elegans, n. sp., . . x 80 1584 



A complete specimen, observed living at Ceylon. In the centre is 

 visible the red central capsule with its three openings, containing a 

 large nucleus of half the size, with numerous nucleoli. The alveo- 

 late calymma encloses a green excentric phaeodium, is surrounded 

 , by a veil of interwoven tangential needles, and forms conical eleva- 

 tions, which enclose the piercing radial tubes. Between these 

 radiate numerous pseudopodia (compare for the single parts, 

 PL 108, fig. 1 and PL 104, figs. 1-3, and their explanation).
