TEBEBELLTJM, Klein. 



Seraphs, Mont/. The*. Conch., Plate CCXVIII. 



Char. Gen. Testa convoluta, cylindrica, apice obtuso ; apertura 

 elongata, labio externo incrassato, truncate, labio interne- plus mi- 

 nusve calloso ; spira brevi ; sutura canaliculata. Operculum cor- 

 neum, parvum, trigonum. 



My late father suggested the true position of this genus long 

 before the discovery of the animal made it certain. Mr. Adams 

 has figured and described the animal in the 'Voyage of the Sama- 

 rang,' and very properly places it among the Strombida. 



Species, Terebellum stjbulatum (pi. cexviii. f. 4, 5), Lamk. — 

 Bulla terebellum, Linn. — var. T. punctatum, Chemn. — T. testa 

 elongata, tenui, laevigata, pallida, triseriatim nebulosa, lineis spa- 

 diceis oblique angulatis, seu punctis parvis vel magnis ornata; 

 sutura oblique incisa, labio externo undulatim truncato, infra 

 linea spadicea marginnto, labio interno paululum incrassato. — The 

 common variety of this well-known shell is mottled, as in f. 4. 

 The lineated variety is not quite so common. The specimen 

 figured No. 5, from Mr. Cuming's collection, with large pear- 

 shaped spots, presents a very beautiful variation. China and 

 Sooloo Archipelago, Adams.
