SPOLIA ZEYLANICA. 
Eliot 2 .. On the Nudibranchs of Southern India and 
Ceylon—in Proc. Zool. Society, 1906, 
pp. 999-1008. 
The list of species is as follows. They all of them belong to genera 
already recorded from the Indo-Pacific, but the variations in the 
anatomy of Trevelyana as illustrated by T. ceylonica are interesting. 
I have examined the original specimens described by Alder and 
Hancock and by Bergh in all cases where they affected the identi¬ 
fications here suggested. They are preserved in the Museums of 
Newcastle-on-Tyne and Copenhagen respectively. 
1. Cuthona tristis (Kelaart). 
? = Cratena cucullata, Bergh. 
2. Scyllsea marmorata (A. & H.). 
? — Sc. pelagica var. orientalis, Bergh. 
3. Hexabranchus marmoratus (Q. & G.). 
= Doris gloriosa, Kelaart. 
4. Trippa intecta (Kelaart). ‘ 
— T. ornata, Bergh. 
5. T. areolata (A. & H.). 
= T. ( Phlegmodoris) mephitica, Bergh. 
6. Discodoris fragilis (A. & H.). 
= D. morphcea, Bergh. 
7. D. concinna (A. & H.). 
— D. concinniformis, Bergh. 
8. Diaulula sp., juven. 
9. Hallaxa decorata (Bergh). [Hallaxa n. n.] 
10. Chromodoris fidelis (Kelaart). 
— Chr. flammulata, Bergh. 
11. Chr. preciosa (Kelaart). 
12. Trevelyana ceylonica (Kelaart). 
13. Doridopsis nigra (Stimpson). 
14. D. rubra (Kelaart). 
Cuthona ( Cratena ) tristis (Kelaart). 
= Eolis tristis, Kelaart 2, p. 491. See Eliot I., p. 686, PL XLIII., 
fig. 5. 
One specimen from Trincomalee, which, when alive, probably 
agreed with Kelaart’s plate of Eolis tristis, since Dr. Willey has 
labelled it with that name. Its appearance as preserved supports 
this supposition. The colour is yellowish white, with grayish 
pigment, formed of minute dots, distributed in bands over the body 
and cerata.
