78 ON THE VICTORIAN LAND PLANARIANS. 



13. Geoplana ivalhallcE, n. sp. 



This species agrees with Geoplana spenceri in shape, and in the uniform dark 

 oHve green colour of the dorsal surface. The ventral surface, however, instead of 

 being blue, is of a light, speckled brown colour. The anterior tip is dark brown. 

 The opening of the peripharyngeal chamber is situate near the middle of the body, 

 but slightly in front, and the genital opening is about half way between it and the 

 posterior end, if anything a little nearer to the posterior end. Length of two 

 specimens when crawling about 37 and 50 mm. respectively. 



I found two specimens of this Planarian at Walhalla, Gippsland, Victoria, one 

 crawling on the top of a stone (in the day-time), and one under a log. 



Locality. — Walhalla (Victoria). 



14. Geoplana fletcheri, n. sp. (Figs. 8, 9). 



Body much flattened ventrally, convex dorsally ; a good deal broader behind than 

 in front ; tapering gradually to the anterior, and much more suddenly to the posterior 

 extremity. Opening into the peripharyngeal chamber a little behind the junction of 

 the middle and posterior thirds of the body. Genital opening somewhat nearer to the 

 posterior extremity of the body than to the opening into the peripharyngeal chamber, 

 and hence very near the posterior end. The ground colour of the dorsal surface is 

 canary yellow, not quite so bright as in G. sugdeni, with a tendency towards the 

 formation of two brown lateral stripes, continued backwards for some distance from 

 the brownish pink anterior tip. In one specimen (Fig. 9), the ground colour was 

 slightly mottled with brown, and, in addition to the two partial stripes already 

 mentioned at the anterior end, there was a faint, narrow, median, brownish stripe 

 running along the posterior half of the dorsal surface. The ventral surface is pale 

 yellow. Length when crawling about 60 mm., greatest breadth about 3 mm. 



This species at first sight resembles G. sugdeni, but may be readily distinguished 

 by the general shape of the body, and the position of the apertures. I have named 

 the species after Mr. J. J. Fletcher, B.A., as a slight recognition of his valuable work 

 on the Australian land Planarians. 



Locality. — Macedon (Victoria).
