STRUCTURE OF SEVERAL FORMS OF LAND PLANARIANS. 285 



Genus Canoplana — Gen. nov., Moseley, 



Body long and worinlike, much rounded on the back, flattened 

 on the under surface, without an ambulacral line. External 

 longitudinal muscular bundles largely and evenly developed over 

 both dorsal and ventral regions. Lateral organs distinct and 

 isolated as in Rbynchodemus, and, as in it, connected by a 

 transverse commissure. Eyes absent from the front of the anterior 

 extremity, but present in two lateral elongate crowded patches 

 placed just behind the anterior extremity and scattered sparsely 

 on the lateral margins of the body for its entire extent. 



Mouth nearly central, pharynx cylindrical. 



Habitat. — New S. Wales. 



1. Cmnoplana coernlea, sp. n., Moseley. Entire body of a 

 dark Prussian blue colour, somewhat lighter on the under surface 

 of the body and with a single, narrow, mesial, dorsal, longitudinal 

 stripe of white. Length 5 cm., extreme breadth 4 mm., mouth 

 central ; generative aperture 8 mm., posterior to the mouth. 

 Parramatta, near Sydney. Under the bark of a species of Eu- 

 calyptus. 



2. Ccemplana sangidnea^ sp. n., Moseley. — Closely resembles 

 C. CcBrulea, with the exception that it is coloured of a uniform 

 light red, which is lighter upon the under surface of the body. 

 Actual length when living 7 cm. ; breadth 4 mm. Parramatta,. 

 near Sydney. Amongst earth at the roots of a Eucalyptus 

 stump. 



3. Canoplana subviridis. — Ground colour of the body greenish 

 yellow beneath. In the mesial line of the dorsal surface is a 

 broad band of the ground colour, bordered on either side by a 

 somewhat narrower but very sharply defined intensely black band. 

 Beyond the black bands externally on either hand lie bands of 

 the ground colour of equal breadth to them ; and beyond these 

 again is a very broad band which extends outwards nearly to the 

 lateral margin of the body, which band is composed of a shading 

 of fine longitudinal streaks of reddish brown, and is bordered 

 on either side by a narrow dark, nearly black, margin, the inner 

 border being more intensely pigmented of the two. The bands 

 and Hnes become narrower and more indistinct towards ths pos- 

 terior extremity, and eventually blend. The immediate anterior 

 extremity of the animal is of a bright burnt sienna colour, darker 

 towards the tip. Length of largest specimen when living and 

 crawling 16 cm. ; breadth 4 mm. ; length of smaller specimen 

 when crawling 12'5 cm. Camden and Parramatta, N. S. Wales. 

 Under dead logs and on bark of Eucalyptus trees.
