368 NOTES ON AUSTRALIAN LAND-PLANARIANS, 



the two patches thus foi-med also become continuous across the back 

 for a short distance just behind the row of eyes. The tip not 

 otherwise sienna-coloured. The median green stripe continues 

 nearly to the tip. 



Length of largest living specimen 11-19 cm. long; 1 cm. wide; 

 largest spirit specimen 7-5 cm. long, 6-5 mm. wide; mouth 

 posterior to anterior extremity 3-5 cm.; genital orifice behind 

 mouth 12 mm. 



Some spirit specimens retain the colour fairly well, but it is 

 usually more or less completely taken up by the spirit ; the lines 

 fade considerably.

We have a number of specimens answering to the above 

 description ; in addition we have met with two variations. 

 Firstly, we have a few specimens in which the outer sienna line 

 on each side is wanting. Secondly, we have a few specimens in 

 which the ground colour is pale greenish-yellow, with two or 

 four sienna lines. Some of these however, may be only immature 

 specimens, as the few young ones so far met with are pale yellow 

 or pale greenish above, and have the two inner stripes complete 

 and distinct only anteriorly, while posteriorly they, as well as 

 the outer lines when present, are broken and indistinct.
