Like many other species of the genus, T. flammea has a 

 wide range of habitation. The Panama variety, collected 

 by Mr. Bridges, is M. Deshayes's T. incomparabilis. 

 Some specimens are concentrically crenulated much more 

 than others.

Terebra ornata. Ter. testa obeso-subulatd, carneo-lac- 

 ted, maculis quadratic purpureis subdistantibus trise- 

 riiilim cinctd, anfractibus convexo-planatis, sulco prope
