Land Planarians, Tasmania and S. Australia. 181 



With this rat-e Victorian species I identify, provisionally at any 

 rate, three specimens received in spirit from Mr. Alexander 

 Morton and Professor Spencer. They agree with the Victorian 

 form in the cliaracteristic broad, flattened body, much broader 

 behind than in front ; in the arrangement of the dark streaky 

 markings on the dorsal surface ; in the absence of markings on 

 the ventral surface, and in the position of the external apertures 

 (the peripharyngeal somewhat behind the middle of the body and 

 the genital about half-way between it and the posterior end). 

 The ground colour is yellow and the streaks or splotches dark- 

 brown or purplish in spirit. In only one specimen, the smallest 

 of the three, is the dark median dorsal line present, and even 

 here not very strongly developed. The largest of the three 

 specimens (in spa-it) measures 27 mm. in length by 6-5 mm. in 

 greatest breadth. 



Localities. — Tasmania (A. Morton, Esq.) ; Lake St. Clair

Genplana /nortoni, n. sp. 



The following 'lescription is taken from live spirit specimens, 

 which are so well pi-eserved and well characterised that I have no 

 hesitation in naming them, although I have not myself seen the 

 animal alive. Four at any rate of the speciiuens reached me very 

 soon after capture and have evidently undergone but little 

 change in colour.* 



Length (in spirit) about 40 mm., greatest breadth 5 mm. 

 Broader, and much less gradually tapering, behind than in front. 

 Dorsal surface strongly convex ; ventral surface concave, with 

 prominent, narrow margins. Dorsal surface yellow, closely 

 mottled all over with small, irregular specks of brown. (The 

 mottling, or marbling, is a good deal coarser in some specimens 

 than in others). Ventral surface similar but paler, with the 

 Ijrown colour less developed and in smaller specks. A very 

 narrow band of yellow, without any brown specks, occupies the 

 pi'oniinent margins. The peripharyngeal aperture is situated in 

 about the middle of the body, and the genital aperture usually 



* Professor Spencer tells me that in life the colour is warmish yellow with warm umber 

 splotches.
