LAND PLANARIANS. 5^1 



the body (in spirit) appears distinctly marked out into three 

 sharply defined though faintly coloured longitudinal bands, a 

 median very pale yellow band, and on each side of it a band 

 of about equal width of much deeper yellow. These bands 

 cannot be conspicuous in life, for I have no record of them 

 in my notes. The curious point about them is that they are 

 so sharply defined, and do not merge into one another. 



The shape of the worm in spirit is just hke that of the 

 typical G. alba, and the peripharyngeal aperture is situate 

 nearly as far back as the junction of the middle and posterior 

 thirds, while the genital aperture is placed at about one- 

 third of the distance between the peripharyngeal and the 

 posterior extremity. 



The cihated pits on the margin of the anterior extremity 

 were distinctly visible in the spirit-preserved specimen. 



A second, much smaller specimen, white all over when 

 alive, with brownish pink tip at the anterior end, very 

 narrow, and about 1 ^ inches long when crawling, appears to 

 be a young specimen of the same. 



Locality. — A moss-grown, rotten log, near the Silver Falls 

 on Mount Wellington. 



Geoplana adce (Dendy).^ 



I identify a single small specimen as a slight variety of 

 this species. In hfe the ground colour of the dorsal surface 

 was whitish or pale greenish. In the middle line was a 

 rather narrow band of ground colour, with a broad dark 

 chocolate-brown stripe on each side of it. The ventral 

 surface was whitish, speckled with pale greenish grey. 



The only distinction which I find between this specimen 

 and typical Victorian examples of G. adce is the absence in 

 the former of the thin median dark line. I refrain, how- 

 ever, from giving a varietal name until more specimens are 

 to hand.

 As shght varieties of this species I identify two specimens, 

 described as follows in my notes on the living worms : —
