 Melibcea Viridis. Kel 4 



Animal gelatinous, transparent, of a greenish vitreous colour. 

 Body covered with hairy filaments. Head small, nearly cir- 

 cular, covered with filaments. Veil large and very expansive ; 

 circular opening lined with cilia. Tentacles 2, about f of an 

 inch long ; capsule small, covered with filaments. Branchiss 

 6 or 7 on each side, unequal, wedge shaped ; placed alter- 

 nately ; base broad ; slightly pedunculated, covered with 

 cilia and filaments, giving a verv hairy appearance ; base 

 brown; the other parts greenish and speckled with dirty 

 white. Foot narrow, of pinkish colour on edge ; and upper 

 surface covered with short filaments. 



Nearly 3 inches long. 



Found on weeds near Inner Harbour ; not common ; can 

 swim very actively. The veil over the head is used as a net 

 doubtless to entangle its prey. The opening is very dilatable. 

 Deposits its ova in a fiat mass ; ova white. 



SCYLLJEA (?) DliACiENA. Kel. 



Animal green ; elongated, narrow. No mantle. 2 tenta- 

 cles placed anteriorly on side of head ; non-retractile; tentacles 

 folded or cylindrical, slightly granular. On the centre of 

 the back there are three unequal wing-like denticulated lobes, 

 of a green colour, with tooth-like processes, tipped red ; sides 

 of the posterior half of body also toothed with two lines of 

 small pointed, red tipped tubercles. Foot narrow, channel- 

 led. Mouth protected by two small semi- orbicular flaps or 

 veils. Orifice on right side. Length nearly one inch. 



I have some doubts as to the propriety of placing this 

 species under the genus Scyllcea. I could not discover any 

 tufted branching on the surface of the dorsal lobes. I propose
