650 SIR c. ELIOT ON NUDiBRANCHS [June 19, 



One specimen is preserved in "Walter Elliot's collection, and two 

 others were found at Newcastle marked as having been sent from 

 Ceylon by Kelaart. 



The largest specimen is 38'5 mm. long, 18 broad, and 15 high. 

 The extex"nal characters of all are much the same. The colour is 

 dull yellow-ochre, with black ring-like spots of irregular outline, 

 the largest about 6 mm. broad. These spots are not as a rule 

 simple ocelli, but areas surrounded by a ring and containing 

 a considerable number (as many as 50) of smaller spots. The 

 black pigment is almost entirely on the papillae, and not on 

 the dorsal skin. Besides these rings there are black spots without 

 a light centre on the margins of the mantle and foot. The number 

 of spots on the under surface is very variable. 



The whole back is covered with thick-set minute papillae, which 

 can be scraped off. They are soft, but contain straight colourless 

 spicules *, The rhinophore-pockets are large but not raised. The 

 perfoliations of the rhinophores are black, but the base and tip of 

 the column are white. The branchial pocket is a conspicuous 

 transverse slit, 10 mm. long and 2-5 broad. Though it has not 

 raised edges, the region all round it is distinctly elevated. The 

 branchiae are six, large, quadripinnate, yellow with a black 

 rhachis. The anal papilla is subcentral, large, yellow with a black 

 crenulated margin. The oral tentacles are long, digitate, yellow 

 with black tips. The anterior margin of the foot is very deeply 

 grooved. The upper lamina is divided in the middle and forms 

 an ample flap on either side. 



The buccal parts had been removed from two specimens, but the 

 teeth were found in the third, though the ribbons of the radula 

 had entirely decayed and it was not possible to state their 

 arrangement with certainty. The formula may have been about 

 25 X 20.0.20. The specimen was small. Some of the teeth are 

 like Bergh's figures of the first lateral of K. annuligera, but their 

 position is no longer plain. The other teeth also agree with Bergh's 

 figures. 



. In two specimens the penis terminates in a transparent colourless 

 stylet about two-thirds of a millimetre long. The end is blunt 

 and not pointed — a shape which is also indicated in Bergh's 

 figures (Semper's Reisen, Heft x. pi. xii. fig. 16). 



These specimens are undoubtedly identical with Kentrodoris 

 cmnuligera, described by Bergh in Semper's Reisen (I. c. and xvii. 

 1890, p. 921). In his description of the Mollusca collected by 

 Kiikenthal at Ternate (Abhand. der Seckenberg. Gesellsch. 

 Band xxiv. Heft i. p. 99) he expresses the opinion that his 

 Kent7'odoris annuligera is the Doris funehris of Kelaart and 

 also the D. maculosa of Cuvier and of Quoy & Gaimard. As the 

 examination of Kelaart's specimens shows, the first of these 

 identifications is correct. The others are perhaps less certain. 

 Cuvier {I. c.) described his D. mactdosa as " presque aussi plat 



* They correspond with Bergh's description in Semper's Reisen, xvii. p. 922.
