HE members of the Tellin 

 family (Tellinacea) are dis- 

 tinctly deep burrowers in 

 sand or mud, and this habit

 the foot to be a powerful organ, and in lengthening 

 and separating the siphons to give them greater 

 power and mobility that they may reach up above 

 the sand to the clear water. The lips also are large, 

 the gills unequal in size, and the mantle fringed with 

 tentacles. The general appearance may be gathered

 applied by Dioscorides and other of the ancients

 are seven British genera in the group, with over a 

 score of native species. 



The Pomegranate Tellin {T. halaustina) had 

 its name suggested to Linnseus by the resemblance
