MOTES on A COLLECTION OF NUDIBRANCHS 
FROM CEYLON, 
By Sir Charles Eliot, K.C.M.G., 
Vice-Chancellor , University of Sheffield . 
I N two Papers published in the Proceedings of the Zoological 
Society of London (1906, pp. 636-691, and 1906, pp. 999-1008) 
I discussed the nudibranchs already recorded from Southern India 
and Ceylon, with special reference to the drawings left by Kelaart, 
some of which were published with the first Paper. Subsequent- 
authors have, in many cases, allowed Kelaart’s names to stand in 
their lists as if they were valid, but have duplicated species by re¬ 
describing the same animals under new names. Kelaart’s species are 
mostly recognizable if his figures are compared with living animals, 
but if they are compared with preserved specimens identification 
is often difficult. I therefore asked Dr. Willey to let me have any 
specimens of nudibranchs he could find in Trincomalee (where 
Kelaart collected) or elsewhere in Ceylon, with notes on the living 
animals, and any suggestions which he could make as to their 
identification with Kelaart’s figures. He has very kindly sent me 
examples of fourteen species, with most useful notes. As a result, 
I am able to give further details about the animals which Kelaart 
called Eolis tristis , Doris fidelis, D. preciosa , and Trevelyana ceylo- 
nica ; also about the Scyllcea marmorata and Doris areolata of Alder 
and Hancock. It is further, I think, clear that Trippa ornata , 
Bergh — Doris intecta, Kelaart, and Discodoris morphcea, Bergh = D. 
fragilis, A. & H. The second specific name of each pair must stand.
