the two halves. The innermost teeth are small and sliglit ; the 

 rest large, strong, and hamate. The last five or six gradually 

 decrease in size. 



The shortness of this radula and its other characters make it 

 probable that the animal is a Trippa. Alder and Hancock 

 thought it showed " some affinity with D. sjjongiosa" and it 

 a|3parently had compound tubercles (" swellings .... and a few 

 tubercular elevations ; the surface is also covered with minute 

 tubercles, particularly on the ridges and swellings "). 



Doris leoparda Keelart. 



Should probably be called Trippa leoparda {JL^^?^v\j)-= Trippa 

 tnonsoni Eliot. 

 The animal depicted in my previous paper in figure 1 of 

 Plate XLY. is inadvertently called Trippa monsoni in the expla- 

 nation of the plates on page 690. It should be called Doris 

 leo-parda, for though the two animals are probably the same, the 

 figure reproduced is Kelaart's sketch of D. leoparda^ which, if it 

 proves to be a Trippa, should be called Tr. leoparda. 



Trevelyana ceylonica Kelaart. 



Eliot, Proc. Zool. Soc. 1904, vol. ii. pp. 86-7. 



The radula shows that the animal described by me is, as con- 

 jectured, Kelaart's Trevelyana ceylonica. It consists of 21 rows, 

 each containing 24-25 teeth, on either side of the rhachis. The 

 first latei'al is larger than the rest and difierently placed, so as to 

 project into the rhachis. All the teeth are awl-shaped. 



GONIODOBIS. 



The buccal parts of G. aspersa and G. citrina are preserved, but 

 in iDoth the teeth are covered with fiesh, so that the small teeth 

 cannot be seen at all and most of the large ones are only partly 

 visible. No formula can be given. 



The large teeth of G. aspersa have a kink in the lower part 

 of the back and a distinct ridge or wing at the side, but no 

 denticles or striations. There is a buccal ring studded inside with 

 prominences. 



None of the teeth of G. citrina can be seen completely, but the 

 upper part clearly bears very fine striations, and it would seem 

 that the outline is not a regular curA-e but swells outwards both 

 on the back and on the inside. Other parts of the buccal mass 

 are preserved, but there is no trace of an armature. 



EoLis militaris a & H. 



= Hervia militaris (A. & H.), 



Fourteen teeth are preserved. They are of the horseshoe 

 shape, with rather long side-limbs. The central cusp is distinct 

 and well formed : on either side are 7 denticles about half its 

 size and close to one another.
