of the row they become more erect and less hooked. The 

 three outermost are erect and bear on the apex a group of 

 hair-like denticles resembling a brush. The intestines are 

 soft and decayed, but no trace of armature was found on the 

 genitalia. 



This animal seems to be a true Thordisa, and one would 

 expect it to prove identical with some of the species already 

 described as Th. macnligera, Th. maculosa,^ and Th. 

 punctulif era.'' But they do not entirely agree with it in 

 external characters, and they differ decidedly in the radula, 

 which in the present species is unusually narrow. The animal 

 must therefore be provisionally recognised as sp. no v., but it 

 has points of resemblance to the Doris setosa^ of Pease and 

 the Doris ari]iona of Kelaart, two forms which ai-e imper- 

 fectly described but could be probably identified with living 

 animals. The soft hair-like texture of the present species is 

 very noticeable.

The notes on the living animal are as follows : "21 x 7 

 mm. Dorsal surface whitish, irregularly mottled with 

 yellowish brown ; a few irregular plum-coloured blotches 

 all round near the edge of the mantle. Tentacles (i.e. 

 rhinophores) brown with white thread-like rings, depressed 

 behind, where they are connected by one longitudinal white 

 line. Branchiae white ; under surface white." 



The liver is of a bright plum colour in the preserved 

 specimen and visible through the lower integuments. The 

 branchiae are eight and simply pinnate. White lines are still 

 visible on them and on the rhinophores. Globular glands are
