 scribed and figured the animal as having separate, long, 

 leaf-like tentacles (folded back on the sides of the shell in 

 front), with minnte ejes at their outer bases ; and the foot 

 is not expanded laterally or behind. This species must be 

 placed in the genus Ehizonis of De Montfort, or Volvula

 in young, but sunken and nearly concealed in full-grown 

 specimens.

 C. 40-100 f. ; P. 25-173 f. In all these cases dropped 

 from the surface of the sea, or voided by fishes and oceanic 

 llijdrozoa. 



Besides the Mollusca, Poraminifera abounded in great 

 variety ; these I have placed in the excellent charge of Dr. 

 Carpenter. I also found some sponge-spicules, which Dr. 

 Bowerbank tells me belong to Geodia Barretti^ an undescribed 

 species.
