 Hab. Bass's Strait ; off Cape Capricorn ; between Cumberland 



Island and Point Slade (Australia), Macgillivray. Algoa Bay. 



This appears so closely to accord with the description of E. 

 lichenoides, M.-Edw., that I have little doubt it is that species; 

 either this or the preceding certainly is, perhaps both. 



6. ESCHARA FUEGENSIS, n. s. PL CVII. figs. 1, 2, 3. 



Cells pyriform, arched above the mouth; a central pore in 

 front, and an avicularium pointing obliquely inwards and upwards 

 on each side ; mouth crescentic (in age the mouth becomes 

 perfectly circular and very small, the cells and the interstices 

 being covered and filled up with a perforated overgrowth). 



Hab. Coast of S. Tierra del Fuego, 30 fathoms, Darwin.
