ing to more than half-way towards the border of the shell ; in the 

 first part of their course from the mouth forwards, the cilia are 

 few or wanting ; the whole brachial apparatus is supported by 

 the small forked process above described, no other part of the 

 apophysary system being calcified. 



Obs. The animal of this genus has been examined in two 

 species, and differs from Megerlia in the relative small size of the 

 ciliated arms : five recent species are known.

Obs. Most authors have misunderstood this form ; Sowerby, 

 in his ' Th. Conch/ tab. 68. figures as T. rubra (Pallas), 

 a specimen of T. Zelandica, which is now in the Collection of 

 the British Museum, and figured by Leach under the false name 

 of sanguinea, which is not Chemnitz's species. T. Capensis, 

 Adam and Reeves, is not the T. Capensis of Chemnitz, and there- 

 fore not the T. rubra of Pallas.
