Fig. 1. Ccelospathis ancorata, n. sp., 



Lateral view of the entire shell. The central capsule is visible between 

 the two valves of the inner shell. The galeae and rhinocannse of 

 the two inner valves are filled up by the black pheeodium. 



Fig. 2. Ccelospathis ancorata, n. sp., 



The two valves of the inner shell ; the galeae and rhinnocannae of which 

 are filled up by the black pheeodium. Between the mouth of the 

 two rhinocannse is prominent the proboscis of the astropyle, arising 

 from the radiate operculum of the central capsule. The latter con- 

 tains numerous crystals and a big dark nucleus. Lateral view. 



Fig. 3. Ccelospathis ancorata, n. sp., 



The rhinocanna or the nasal tube of one valve, and the latticed frenulum 

 which connects its mouth with the top of the galea. 



Fig. 4. Ccelospathis ancorata, n. sp., . 

 Distal end of a style. 



Fig. 5. Ccelospathis ancorata, n. sp. , .
