marginal stripes ; none of the stripes well defined, however. The 

 ventral surface is cream-coloui*ed, with no markings, and is 

 continued up round the sides of the body to form a border on 

 either side of the dorsal surface, very sharply marked oft" from the 

 dark-coloured portion. Hence, when the animal is viewed from 

 the upper surface we see a broad median band of a dark colour 

 bordered on either side by a narrow margin of pale cream colour, 

 while in the dark band itself we can recognise three longitudinal 

 stripes of darker colour than the rest. 



In spirit the animal measures about 18 mm. in length, by 

 mm. in greatest breadth. The body is ovoid in section, some- 

 what flattened, especially on the ventral surface, but thick and 

 with broadly rounded mai'gins. Exactly the same colouration is 

 visible as in the living specimen, except that the dorsal surface 

 appears to be darker. The light margins are still conspicuous 

 from the dorsal surface. The peripharyngeal aperture is slightly 

 behind the middle and the genital aperture slightly nearer to it 

 than to the posterior end. The eyes are very abundant, arranged 

 as usual and continued down the light-coloured sides of the body 

 to the posterior end. 



This variety differs from the ordinary Victorian form chiefly 

 in the absence of the narrow and sharply defined band of pale- 

 yellow colour on each side of the dark median dorsal line. It 

 appears to be a fairly well marked variety.

A single specimen of this common New South Wales and 

 Queensland species was obtained by Professor Spencer at Bedlam 

 Heights, in January 1893, and, together with coloured drawings 

 of the living animal, placed by him in my hands. I have no 

 hesitation in making the identification, although, curiously 

 enough, the species has not yet been found in the intervening 

 colony of Victoria. The general shape of the body (in spirit),
