PEEFACE. 



The first plate in this Nineteenth Decade represents one of the 

 most cimous of the small Lizards of the Colony, remarkable 

 for the entire absence of external ear-drums, the Tympano- 

 cryptis lineata. 



The second plate figures for the first time the natural colours 

 of life of one of the largest of the so-called Whiting, amongst 

 our best food fishes, the Sillago ciliata. 



The third plate represents the Skipjack of all English-speaking- 

 fishermen, the Temnodon saltator, remarkable for its almost 

 world-wide distribution, and which is common in our Bay and 

 fish shops most months of the year. 



The fourth plate represents, for the first time of the natural 

 colours, another of our very common food fishes, popularly called 

 Roughy, the Arripis Georgianus. 



The next three plates are devoted to illustrations of Mr. 

 MacGillivray's contributions of specimens to the Museum, and 

 descriptions of our Victorian Polyzoa. 



Plate 188 represents, the so-called Cuttle-fish bone of our 

 commonest species of Sepia, not, however, figured before, the 

 Sepia apama.
