734 NOTES ON SOME LAND PLANARIANS. 



very much wider than the pinkish white strij^e.s. The ground 

 colour of the ventral sui'face is ashy grey with three stripes of 

 pinkish white, a median one of moderate width and a marginal 

 one on each side of little more than half the width. The inter- 

 vening band of ground colour on each side is only a little wider 

 than the median white stripe. 



In living specimens all the light stripes are very clear and 

 distinct, and persistent to both extremities. In spirit they lose 

 their pinkish tint but remain plainly visible. 



In spirit the body is long and narrow, convex above and 

 flattened below, rounded in front and much more pointed behind, 

 about 24 mm. in length by 2*5 mm. in greatest breadth. The 

 peripharyngeal aperture is situated a little behind the middle of 

 the ventral surface and the genital aperture a little nearer to it 

 than to the posterior extremity. The pharjiix, as exserted in 

 spirit, is narrow and cylindrical. 



I received from Mr. Steel four well-preserved specimens of this 

 worm collected under logs at Wentworth Falls, together with his 

 notes on the living animal. He also sent me two specimens in 

 spirit from Blackheath, which he thought might be Messrs. 

 Fletcher and Hamilton's Khynchodemus coxii. It appears to me 

 certain, however, that one at any rate of these belongs to R. 

 victorice, var. Moreover Mr. Fletcher informed me some years 

 ago that Rhynchodemus coxii is really a Geoplana. 



This new variety bears a close resemblance to the type of R 

 victorice, from Croajingolong, which I described in 1890 from a 

 single specimen only.* It differs from it, however, in the presence 

 of an additional pair of narrow white stripes on the dorsal surface. 



I have much pleasure in associating the name of the discoverer 

 with this new variety, as a slight recognition of the valuable 

 assistance which he has repeatedly rendered me in my investiga- 

 tions on the Cryptozoic Fauna of Australia.
