ELIOT : NTJDIBKANCUS FROM THE TACIFIC. 237 



Through the kindness of Mr. E. A. Smith I have been allowed to 

 examine both the type-specimen of Abraham's Doris WeUmgtonensis 

 in the British Museum, and also a very fine specimen from Otago. 



The type-specimen is not well presei-ved, but agrees with Abraham's 

 description of its external characters. There are whitish tubefcular 

 spots between the large flat pustules, and the oral tentacles have 

 a distinct pit at the apex. It would appear, however, from a com- 

 parison with the other specimen, that this curious feature is due to 

 distortion by the preserving fluid. Abraham says there is no groove 

 on the anterior margin of the foot. I think there is one, but there 

 are so many lines and wrinkles in this part of the animal that it 

 is hard to say which are natural and which are due to distortion. 

 The branchiae are seven, bushy, tripinnate. It looks as if there were 

 a few separate plumes rising from the floor of the cavity here and 

 there, near their bases. The radula was extracted. It consists of 

 48 rows with about 50 teeth, at most, on each side of the rhachis, 

 which is broad, without a central tooth, but with several irregular 

 longitudinal folds. The first lateral projects almost at right angles 

 into the rhachis. It has a short, low hook, and a long thick base. 

 The other teeth are hamate, of the same type, but the hook is longer, 

 and the base shorter. The outermost teeth are smaller, but not 

 degraded. There is a very strong labial cuticle, but no labial 

 armature. 



The second specimen is a magnificent example of the animal. It 

 is 137 mm. long, 84-5 broad, and 42-5 high. The mantle-margin is 

 about 20 mm. wide and 7 thick. The foot is long and broad (76 mm.), 

 and just covered by the mantle. The colour, above and below, is 

 a uniiorm orange yellow. The under parts are very soft and flaccid. 

 The anterior margin of the foot is distinctly grooved. There is a rent 

 in the middle, and it is impossible to say whether there was a natui-al 

 notch or not. The dorsal surface is much harder, with an almost 

 scaly feeling. The back is moderately arched, and covered with large 

 flat warts, of which the biggest are circular and measure about 9 mm. 

 across. They are arranged in five rather irregular rows. Between 

 them are smaller and lower warts. Outside these large warts are 

 others, very numerous, extending right down to the mantle-edge, and 

 decreasing gi-adually in size outwards. They are softer than the central 

 warts, but higher, and sometimes quite pointed. Possibly the back 

 has been flattened by accidental pressure. The edge of the mantle is 

 undulated. The openings of the rhinophores and branchiae are only 

 slightly prominent, crenulate, but not tuberculate or stellate. ^ 



The branchiae are seven, tripinnate, and sometimes quadripinnate, 

 not very large, considering the size of the animal, but much ramified. 

 The anal papilla is subcentral. 



The internal organs are not very weU preserved, and have been 

 severely injured by two glass skewers which have been driven through 

 the animal, apparently to preserve its form. 



The blood- gland is large and much branched. In the central 

 nervous system the common commissure is remarkably large and 

 thick, but, considering the size of the animal, the eyes, which are
