THE VICTORIAN LAND PLANARIANS. 31 



in the middle of the yellow stripe. Some of the specimens brought by Professor 

 Spencer from Croajingolong (in spirit), which otherwise resemble G. cccrnlea, have 

 the dorsal light band thus divided into two by a dark line, and I find that I had 

 accordingly placed them in separate bottles away from those which I definitely 

 identified with ccei'ulea. Probably, therefore, these Croajingolong specimens are also 

 referable to G. dendyi, so that we have the two closely allied species, caridca and 

 dendyi, inhabiting the Croajingolong district. The Croajingolong specimens appear 

 to be more flattened than those described by Professor Spencer. 



6. Geoplana walhallcc, Dendy. 



Only a single specimen of this species has been obtained since it was first 

 described, and that by Professor Spencer, who found it in the country lying between 

 Marysville and the source of the Yarra along the Wood's Point Eoad, and has 

 described and figured it in the Proceedings of the Eoyal Society of Victoria.* The 

 genital opening, as figured by Professor Spencer, is much nearer to the peripharyngeal 

 opening than in the type specimens. 



7. Geoplana frosti, Spencer. f 



This species, as pointed out in the original description, is obviously very closely 

 related to G. walhallce, from which it is distinguished only by the presence of two 

 light yellow stripes one on each side of the mid-dorsal line and by the absence of the 

 brown speckles along the mid-ventral line. I do not feel disposed to lay any stress 

 on the latter character. Professor Spencer has figured an interesting connective 

 form in which the dorsal yellow stripes are absent throughout the greater part of the 

 length of the body. 



I have identified^ a small specimen which I found near Mount Wellington, 

 Gippsland, with this species. In life the ground colour of the dorsal surface was 

 very dark indigo blue, so dark that the exact colour was difficult to determine, with 

 two narrow stripes of whitish separated by a very fine, dark, mid-dorsal line. The 

 ventral surface was pale brown flecked with darker brown. Even in tlie spirit- 

 preserved specimen a light mid-ventral line, devoid of specks, is distinctly visible, 

 and the opening into the peripharyngeal chamber is situate in about the centre of 

 the body and the genital aperture (?) only a short way behind it. The specimen 

 (in spirit) measures 12mni. in length by a little under 3mm. in greatest breadth.
