* Apl. Its color is different shades of brown 

 tinged with blue or purple; lungs fan-shaped, 

 variegated with stripes of dusky brown and 

 white. 



As the lungs are visible without dissection, 

 we have risked a specific distinction, by means 

 of this part, with regard to this and the follow- 

 ing species. There are already instances of 

 specific characters taken from the interanea of 

 this tribe of animals. See Ascidia. Gm. Lin.
