164 THE VICTORIAN NATURALIST. 



determine to stay in camp another day and to wait patiently for 

 the morrow. Towards midday, to our joy, it clears up. We 

 spend the time collecting in the scrub round about. The ash 

 trees here and everywhere about the track have their leaves 

 matted together by the webs of a tortrix moth. The caterpillar 

 is a large green and black one, and a number are taken home. 

 Owing to inability, however, to obtain the food plant, only one 

 has since emerged, and the imago proves to be a large red-brown 

 moth with a double white line across each wing, and is as yet 

 unnamed. Under fallen logs and the bark of trees we are 

 successful in finding numerous specimens of land planarians. 

 The most common form is Geoplana spenceri. Next in abundance 

 is a new species now found for the first time, and to be known as 

 G. dendyi.* The animal measures, at its greatest length, some 

 5 inches, and in width ^ inch. Its upper surface is usually of 

 dark green colour, and its ventral somewhat lighter, with patches 

 of blue along the median line, varying in extent in different 

 animals. The tip has the orange colour typical of land planarians, 

 whilst along the back run two light yellowish lines, separated 

 from each other by a narrow median line of ground colour. 

 The body when at rest has, in transverse section, a characteristic 

 triangular shape. The sides of the body are covered with blue- 

 white spots, easily seen under the lens. This species is common 

 in these parts, and occurs in the high ground from the source of 

 the Yarra back to nearly Marysville, though it has not as yet 

 been found in the Yarra valley, where G. spenceri is plentiful. 



In this same part we find another new form, which is now 

 called G. frosti* after the leader of our party. When at rest 

 it is somewhat fiat and leaf-like. Its upper surface is of a dark 

 brown or green colour, with a bluish " bloom" like that of a fruit. 

 The ventral surface is light yellow coloured, with brown speckles, 

 absent along the median line, and along the back run, as in 

 G. dendyi, two light lines separated by a median dark one. 

 This is not very common, and its distribution is identical with 

 that of G. dendyi, from which, however, it can be clearly dis- 

 tinguished by its light ventral surface and flattened shape when 

 at rest. 



In the same part we find stray specimens of G. walhallce, 

 G. alba, G. mediolineata, and G. sulphurea (now for the first 

 time recorded from Victoria, having only previously been found 

 in New South Wales), together with two examples of the rare and 

 curious land Nemertean. This is worm-like in shape, and about 

 y^ inch in length, with a light yellow coloured body and a brown 

 stripe along its back. It lives under the bark of trees, and has 

 the power of putting out a curious white proboscis from the

 where G. dendyi and frosti are fully described and figured.
