Description. The head is small, sub-oval, flattened, with the snout rather 

 pointed. The mouth is small; the tongue is small, arrow-shaped, and pointed in 

 front, free only at its tip, and for a short distance along its anterior and lateral 

 margins. 



The nostrils are anterior. The eyes are lateral, and rather large for a Siren, 

 and are of a dusky-grey colour. The neck is contracted but slightly, and has a 

 single spiracle on each side, concealed by three fleshy prolongations, with fim- 

 briated edges, the anterior very small. 



The body is eel-shaped. The tail is long in proportion, thick, and rounded at 

 its root, but is soon compressed laterally, and is ancipital near its tip, though 

 hardly furnished with a rayless fin, as in the two last species. The anterior 

 extremities, which alone exist, are very small, and terminate each in three minute 

 unarmed fingers.
