Notes on some Victorian Land Planarians. H7 



from a small band-like space on either side of the light lines 

 (Fig. o). The ventral surface varies in colour in dark 

 specimens, being of the same green colour as the dorsal, with 

 always larger or smaller patches of cerulean blue along the 

 median line. In light-coloured ones, this (Fig. 5) colour may 

 form a band along the greater part, or even the whole length, 

 of the body, and may show indications of a median darker 

 stripe in the mid ventral line. 



This appears to be a very distinct species, and was found 

 in considerable numbers under fallen logs, together with 

 G. spenceri. It is the most abundant form along the ridge 

 of high land separating the vallej's of the Yarra from the 

 Thompson River, and was onl}^ found in this district. Seen 

 under the lens, the dark green or bluish skin, with its light 

 dorsal bands and blue-white spots, is perhaps more beautiful 

 than that of any other planarian, and I have much pleasure 

 in naming the species after Mr. Dendy, who has already 

 described some twelve species of Victorian land planarians. 



Geoplana frostl, sp. n. (Figs. G, 7, 8, and 9). — Body when 

 at rest, flattened and leaf-like ; when clawling, elongate and 

 tapering equally at both ends. The opening into the peri- 

 pharyngeal chamber, in a spirit specimen ] inch long, lay 

 slightly in front of the middle of the ventral surface. The 

 genital aperture lay one quarter of the distance between the 

 peripharyngeal opening and the posterior extremity. The 

 dorsal surface is either dark brown (Fig. (i), or dark green 

 (Fig. 7) in colour, in both cases with a bluish surface tinge, 

 like the bloom of fruit, due probably to the enormous number 

 of blue rod cells lying in the skin. Under the lens, the rods 

 or groups of rods can be seen as fine points. The typical 

 form has two light yellow stripes, separated from each other 

 by a thin median dorsal line of body colour, running from 

 the posterior extremity to the anterior orange tip. The 

 ventral surface is light yellow in colour, though this is 

 almost concealed by brown speckles absent along the median 

 line, where is a well marked band of body colour, visible 

 even in spirit specimens. 



This species agrees with G. demliji in its dark upper surface 

 with two light stripes, but oan be easily distinguished from 

 the latter by its flattened form when at rest, and its light- 

 coloured ventral surface. 



One specimen found was remarkable for the slight 

 development of the light stripes, which were only present at 

 the posterior end, and were continuous with a slightly
