the distinction becomes even more strongly marked, in some^ 

 specimens the lateral and marginal lines having almost vanished 

 by bleaching, while the median one remains strong and con- 

 spicuous. 



So far as my own observation goes the species is confined to 

 New South Wales, while all the specimens from Victoria or 

 Queensland wjiich I have seen belong to the variety. 



The eyes are very numerous, and in well preserved specimens 

 are conspicuous and readily seen. Round the anterior tip in a 

 single row as usual, thickly grouped, a few mm. behind the tip, 

 at which part they extend on to the dorsal surface as far as to 

 encroach on the lateral stripes. An irregular wavy line of ej^es 

 extends along the sides to the extreme posterior end. 



Type specimen in Australian Museum; register number G. 1514. 



In a paper published in 1891,* Professor Spencer describes 

 and figures a planarian from the Upper Yarra, Victoria, as a variety 

 of G. mediolineata, Dendy, coming between that species and 

 G. quinqueJineata, F. k H. I am of the opinion that this 

 specimen is a somewhat abnormal example of the present variety. 



For the following species from Southern Queensland sent to 

 me, some alive and some in an excellently preserved state, I have 

 to thank my brother, Mr. John S. Steel, whose descriptive notes 

 on the living worms have been most useful to me.

 (PI. VI. fig. 2.) 



In the median line of the dorsal surface in a specimen of 

 ordinary size is a bold sharp pale brown band, about | mm. 

 broad, extending from tip to tip. In the centre of this bard 

 there is a very narrow line of pure white running its length 

 in the centre. On either side of the median line a broad 

 band of dark brown, varying to dark olive, bro aest in the
