DORIDOEBIDES GARDINERIT. 279 
Doridoeides gardineri: a Doridiform Clado- 
hepatic Nudibranch. 
By 
Sir Charles Eliot, 
Vice-Chancellor of the University of Sheffield ; 
and 
T. J. Evans, 
Lecturer in Zoology in the same University. 
With Plates 15 and 16, and one Text-figure. 
The nudibranchiate mollusc which forms the subject of this 
paper presents an unusual combination of characters. It has 
the external appearance of a Dorid, except that it has no 
gills, but its digestive organs are arranged on the cladohepatic 
plan. It was originally described by Sir Charles Eliot as 
Doridomorpha gardineri in Mr. J. Stanley Gardiner’s 
‘Fauna and Geography of the Maldives and Laccadives, 
Nudibranchiata,’ pp. 544-5. Professor Bergh, however, has 
pointed out (‘‘ Ueber clado- und holohepatische nudibranchiate 
Gastropoden,” ‘Zool. Jahrb.’ Bd. xxiu, Heft 6, p. 740) that 
~ Doridomorpha was used in 1832 by Audouin and Milne 
Edwards. The animal to which they gave the name cannot 
now be identified, but it is unfortunately incorrect according 
to the laws of nomenclature to apply it to a new form and 
Doridoeides is now proposed as a substitute of equivalent 
meaning. 
The original description was made from a single specimen 
obtained by Mr. Stanley Gardiner in the Fiji Islands
