Hab. Sooloo Sea. 



This genus differs from Polycera, as defined by Cuvier, in wanting the frontal veil, in 

 the surface of the body being smooth, in the possession of but two simple horn-like tubercles, 

 and in the dorsal tentacles being swollen at the base ; the two cylindrical, truncate labial 

 appendages are also peculiar. In the figure the proboscis is represented as exserted, giving 

 a peculiar character to the head, which it does not possess in the ordinary passive condition. 



62. GONIODORIS, Forbes.

This, though a small species, is very elegantly coloured, and is among the most beautiful 

 of a group which contributes, by its variety of form and colour, to enliven the solitudes of 

 the ocean.

Hab. Caramata Passage, near Biliton. 



The figures that most nearly resemble this beautiful species, which we have dedicated to 

 our zealous friend Mr. Adam White, are the Doris magnified of Quoy and Gaimard (Voy. 

 Astrol. t. 20. f. 1) and an unnamed Doris, marked "Banks, Icon. ined. 25, Endeavour River," 

 represented in Mrs. Gray's work on Molluscous Animals.
