Fig. 1. Ccelospathis ancorata, n. sp., . . . x 50 1754 



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

 the two valves of the inner shell. The galese and rliinocannte of 

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



Fig. 2. Ccelospathis ancorata, n. sp., . . . x 100 1754 



The two valves of the inner shell ; the galeae and rhinnocanuas of wliich 

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

 two rhinocannae is prominent the proboscis of the astropyle, arising

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

 which connects its mouth with the top of the galea.
