ELIOT — NUDIBEANCHS. 413 



Java, for which I am indebted to Mr. E. A. Smith, of the British Museum (Natural 

 History), contains : — 



1. FJiidiana inca, 4 specimens. 



2. Fhyllidia nobilis, 1 small specimen. 



3. Flocamopheriis imperialis, 1 small specimen. 



4. Five specimens of a Doridopsis, the largest about 20 mm. long. They have a 

 brilliant and elaborate coloration and are probably a new species. 



In tbis list it will be seen that there is a form, Ph. inca, hitherto known only from the 

 west coast of America. Mr. Gardiner's collection cannot be said with certainty to 

 contain any form which is associated with another region, but the resemblance of 

 Phyllidiopsis carmata to a species from the western tropical Atlantic is very striking. 



The colours of the specimens have begun to fade, but when I first received them, 

 many (e. g., Hexabranchus, Thordisa crosslandu, Fhyllidia) had preserved in formaline 

 what I know from seeing them in their native haunts to be their natural coloration. 



I therefore caused coloured drawings of the more remarkable animals to be made 

 without loss of time, and they are now reproduced. 



1. Doridoeides gardineri, Eliot. 



See Eliot and Evans, in Q. Journ. Micr. Sci. vol. lii. part 2 (March 1908). 



This form being considered to be of unusual interest was described separately by 

 Mr. Evans and myself, with a somewhat full account of its anatomical structure and a 

 discussion of its affinities. To this paper the reader is referred for further details, but 

 part of the description there given is now reproduced : — 



Eleven specimens labelled Coetivy and preserved in formol. Coetivy is the southern- 

 most island of the Seychelles group, and Mr. Gardiner's notes state that the nudibranclis 

 obtained there were " all from the reefs, which differ from those of the Chagos 

 archipelago in being almost completely covered with Zostera *." It is probable that the 

 animal adheres to the leaves of the Zostera and harmonizes with them in colour. 



The natural shape seems to be flat and nearly circular, but the preserved specimens 

 are bent in various ways and have the edges turned inwards. One which seems to have 

 kept its form fairly well is 10 mm. long, 9 broad, and 2 high. These are the average 

 dimensions of the consignment. In the individual mentioned the foot is 6 mm. long 

 and 3 broad, but was evidently much wider in life as the margins are bent and rolled 

 up. The free part of the mantle starting from its junction with the foot is 35 wide. 

 It can be seen from the outside that about 2'5 mm. of this space are filled with dark 

 internal organs and that only about 1 mm. of it corresponds to the mantle margin 

 generally found in Dorids. The genital orifice is about 4 mm. from the anterior end, 

 and the anus is about 2 mm. behind it. 



The animals are of a greyish-green colour, a little darker in the centre where the 

 internal organs show through, and lighter at the edges where there are none. Practically
