(Rotuma). It was small (6°5 mm. by 5°5) and much hardened 
so that a satisfactory anatomical investigation was impossible. 
Mr. Crossland and Sir C. Eliot both examined it and could 
find no trace of a blood gland or of a second spermatotheca 
but, as those organs are characteristic of the Dorididz, and 
as Professor Bergh had described them as present in 
Doridoxa, an externally similar gill-less doridiform animal. 
they did not venture to regard their absence as certain, and 
tentatively referred Doridomorpha to the Doridoxide, 
adding that it might possibly prove to be the type of a new 
family. An examination of more numerous and better 
preserved specimens obtained by Mr. Stanley Gardiner on 
his last journey to the Seychelles shows that this is the case. 
The second spermatotheca and blood gland are really absent 
and the animal has a ramified liver. It is, therefore, despite 
its general resemblance to Doridoxa, not very nearly allied 
to it and cannot be placed in the same family. 
Doridoeides gardinerj, sp. nov. 
= Doridomorpha gardineri Hhot (in Nudibran- 
chiata of J. Stanley Gardiner’s ‘Fauna and 
Geography of the Maldives and Laccadives,’ 
vol. i1., part 1, 1904). 
Kleven specimens labelled Coetivy and preserved in formol. 
Coetivy is the southernmost island of the Seychelles group, 
and Mr. Gardiner’s notes state that the nudibranchs 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
