32 ART. 1. — CHARLES ELIOT: 



Japan is a new locality for this species which lias hitherto 

 been recorded from India, Ceylon and South Africa. 



Genus Phyllidia Cuv. 



This genus is represented by three specimens, which call for 

 no comment except a record of their distribution. JPhyllidia 

 nob ills is represented by two individuals from the Bonin Islands 

 and Ph. pustulosa by one from Okinawa Island. 



JDoridopsis rubra Kelaart. 

 var. nigromaculata.

(Plate II., fig. 10). 



Six specimens labelled Ariake Bay, Hiuga, and three labelled 

 Misaki. The largest is 69 mm. long and 45 mm. broad. The 

 texture is soft and flably. A coloured drawing represents the 

 colour in life as transparent red of a brownish tinge and not 

 rosy. The branchiae and tips of the rhinophores are of a deeper 

 and brighter red but still not rosy. The stalks of the rhinopho- 

 res are white. In the preserved specimens the edges of the man- 

 tle, which are extremely thin, show a pale border which is not 

 distinctly marked in the drawing. On the dorsal surface are 

 bold black blotches, which vary in number in different specimens 

 but never leave the impression that the colour is proponderatingly 

 dark. Often there are also a few faint dark lines forming an 

 imperfact reticulation. 



The dorsal surface is quite smooth and the chief structural 

 characters both external and internal agree with previous descrip- 

 tions of D. rubra. The rhinophores are set far forward, the 

 branchiae far behind. The branchiae are 6, stout and voluminous. 

 They are completely everted in all the specimens but the pocket 

 though very shallow has not entirely atrophied. In one specimen 

 however the hinder part of its edge has disappeared and the 

 ordinary dorsal surface runs up to the roots of the branchiae with-
