which has a similarly gorgeous coloration, though there are some 

 differences of detail. For instance, in Kelaart's animal the 

 rhinophores have not red tips, but a red ring below a black tip. 



Elysia pictcc Yerrill, from the Bermudas, has a somewhat 

 similar brilliant coloration, and also the unnamed species noticed 

 by Magarelli in his " ISIote biologiche sugli Opisthobranchi del 

 Golfo di Napoli" (Atti della Soc. Ital. Milano, 1903, vol. xlii. 

 p. 283). 



It is possible that these forms are not true Elysias, but belong 

 to Thioridilla or some allied genus. 



Elysia punctata Kelaart. (Plate XLYI. fig. 5.) 



(Kelaart, 1. c. II. p. 493. Cf. Elysia nigrojninctata Pease, 

 Amer. Journal of Conchol. 1870-71, p. 304; and Bergh, 

 Journal des Mus. Godeffroy, Heft ii. 1873, pp. 80-82.) 



This species appears to be the same as Elysia nigropunctata 

 Pease ; and as the plate indicates that the rhinophores and the 

 pericardium are boixlered Avith red, it probably represents the 

 var. sanguinea of Hedley (Mem. of Australian Mus. iii. 7, March 

 1897, p. 486). 



The name punctata (1859) has priority over nigropunctata 

 (1871).
