what widely apart. No side grouping. Length when crawling 

 13 to 18 mm. by less than 1 mm in width. 



In a spirit preserved specimen which is 16 mm. in length, the 

 peripharyngeal aperture is 9 mm. from the anterior end and the 

 genital opening 1 2^ mm. 



Hob. — Petersham, near Sydney; common in my garden living 

 amongst grass. I got this elegant little planarian feeding on 

 dead slugs which I had casually left under a damp sack lying on 

 grass in the shade of my house. By keeping up this mode of 

 trapping them I secured specimens during the greater part of the 

 year, but they are most abundant in the summer months. During 

 October and November, 1889, on a very limited area of ground, 

 some five or six square yards, I captured under sacks over 200 

 individuals. 



I have not met with this species anywhere else, but if, as is 

 certainly the case in my garden, it burrows amongst the roots of 

 grass, it might readily be overlooked. It may possibly be an 

 introduced form, though I have failed to find a description of it 

 in Prof, von Graff's monograph before-mentioned. The species 

 which appears to come nearest to it is Geoplana gamblei, Graff, 

 from North Celebes, but differs in being several times larger and 

 in having a sharply defined dorso-medial band.

Planaria elegans, Darwin, (i, p. 244); non Geoplana elegans, 



Darwin, Muller and Schultze, (2, p. 29); non G. elegans, 



Darwin, Graff, (12, p. 328). 



When I gave the name G. elegans to a land planarian from 



Queensland, I was unaware that it was preoccupied by Darwin 



for a species from Rio de Janeiro, and having since ascertained 



the fact, I now desire to re-name the species as above.
