Doris.] GASTROPODA. 563 



are 50 to 65 teeth ; the first lateral projects almost at right angles into 

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

 first 15 teeth on either side are rather low, with a long base, so that 

 the lower part of the back is a mere lamina. The three outermost are 

 thinner and smaller. None are denticulate. The teeth are figured by 

 Hutton (T.N.Z.I., xiv, pi. 6, f. G). Mantle-spicules are absent. The 

 other internal organs have also been described by Sir C. Eliot. 



Type in the British Museum. 



Hob. Auckland to Dunedin, in sheltered rocky places ; not 

 common. 



Remark. This species is restricted to New Zealand. 



UNDETERMINED SPECIES. 

 Doris granulosa, Abraham. 



Doris granulosa, Abraham, P.Z.S., 1877, 253, pi. 29, f. 1-3 ; M.N.Z.M., 

 126 ; Eliot, P. Mai. S., vii, 344. 



Several specimens of this form are in the British Museum, and 

 appear to correspond with Abraham's description of the external 

 characters. I opened two, but found the internal organs, including 

 the ribbon of the radula, entirely decayed. Only scattered teeth of 

 the ordinary hamate type remained. 



The form is probably a small Archidoris perhaps A. nanula, Bergh 

 but its appearance in life is unknown, and the preserved specimens 

 present no characters which would justify identification. The species 

 can accordingly be neglected. (Eliot.) 



Doris longula, Abraham. 



Doris longula, Abraham, P.Z.S., 1877, 253, pi. 29, f. 4, 5 ; M.N.Z.M., 126 ; 

 Eliot, P. Mai. S., vii, 345. 



The same may be said of this form. Like D. granulosa, it has lost 

 its colour, the intestines are decayed, and it can only be said that it 

 had rather stout hamate teeth. 



Hutton (T.N.Z.I., xiii, 203) doubtfully identifies with D. longula 

 specimens deposited by him in the Canterbury Museum, but his 

 description is not full, and it is difficult to say whether his animal 

 is really the same as Abraham's, or to what genus either is referable. 

 (Eliot.) 



Archidoris sp. 



Archidoris sp., Bergh, Semper's Reise Philipp., Malac. Unters., vi, 1904, 34 ; 

 Benharn, T.N.Z.I., xxxvii, 317. 



The animal was somewhat hard and stiffened ; the back fairly 

 smooth, but finely granulated towards the margins ; the rhinophores, 

 lying far forward, have the club much foliated. The foot is large ; its 

 margin not broad ; the tail short. Colour in life, pale orange.
