Short Descriptions of Xeiv Land Flanarians. 37 



red lilies running all down the dorsal surface of the body, 

 and dividing it longitudinally into three almost equal parts. 

 Several specimens were obtained, the usual size of which 

 when crawling was about 35 mm. in length, and To mm. in 

 greatest breadth. The body was more C3dindricnl than in 

 fully gnnvn typical examples of G. alba. 



The specimens look as if they were young. One, 

 considerably larger than the remainder, has the led stripes 

 less distinct. On the other hand, I have seen small 

 specimens of G. alba from other localities coloured in the 

 typical manner, without any red stripes. 



All the specimens of the variety roseolineata were 

 obtained along the railway line between Korumburra and 

 Loch, South Gippsland, Victoria, by Professor Spencer, 

 July 1891. 



Geoplamt hoivitti, var. obsoleta, nov. 



Body tapering gradually in front, much more abruptly 

 behind. Ventral surface very flat, dorsal surface very 

 strongly arched. Length, when crawling, about 40 mm.;, 

 greatest breadth, about 3 mm. Opening of peripharyngeal 

 chamber (in spirit) somewhat behind the middle of the 

 ventral surface : genital aperture about half-way between 

 the peripharyngeal aperture and the posterior end. Eyes 

 sparingly arranged, almost in a single row, on the sides of 

 the head (? round the front also). 



The gi-ound colour of the dorsal surface is rather deep 

 pi-imrose yellow, and there are only two, dai^k chestnut 

 brown stripes, one on either side of a somewhat wider 

 median band of clear ground colour. Outside the dark 

 stripes the ground colour is flecked with minute specks 

 of a lighter chestnut brown ; at each side of the head these 

 specks run together to form an almost continuous but 

 irregular stripe for a short distance. 



The ventral surface is nearly white, with no markings, 

 and the anterior extremity is reddish brown. 



This variety differs from the type of Geoplana hountti in 

 the absence of the outer dark stripes. In one of the two 

 si)ecimens obtained the dark specks also are only faintly 

 indicated. 



Both .specimens were collected by Professor Spencer and 

 Mr. C. French near Narrewarren, South Gippsland, Victoria, 

 July J 80 1.
