Show the two halves. The innermost teeth are small anil slight; the rest large, strong, and hamate. The last five or six gradually decrease in size. Hie 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. spongiosa ," and it apparently had compound tubercles (" swellings . . . . and a few tubeicular elevations ; the surface is also covered with minute tubei cles, particularly on the ridges and swellings "). D oris leop ar da Keelart. Should probably be called Trippa leoparda (Kelaart)= Trippa monsoni Eliot. The animal depicted in my previous paper in figure 1 of Plate XLY. is inadvertently called Trippa monsoni in the explanation of the plates 011 page 690. It should be called Doris leoparda, for though the two animals are probably the same, the figuie lepioduced is Kelaart s sketch of D. leoparda, which, if it proves to be a Trippa, should be called Tr. leoparda. T r e v e l y an a c e y lo n ic a Kelaart. Eliot, Proc. Zool. Soc. 1904, vol. ii. pp. 86-7. Ihe radula shows that the animal described by me is, as conjectured, Kelaart's Trevelyana ceylonica. It consists of 21 rows, each containing 24-25 teeth, 011 either side of the rhachis. The first lateral is larger than the rest and differently placed, so as to project into the rhachis. All the teeth are awl-shaped. G o nio do ris. The buccal parts of G. aspersa and G. citrina are preserved, but 111 both the teeth are covered with flesh, 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 lowrer part of the back and a distinct ridge or wing at the side, but 110 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 curve but swells outwards both on the back and 011 the inside. Other parts of the buccal mass are preserved, but there is 110 trace of an armature. E olis m il it ar is 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. 1 9 0 6 -] OF SOUTHERN INDIA AND CEYLON. 1007 |
