only at the anterior portion can the markings be followed. The 

 measurements are : — 



Length of the body . . . . 50 mm. 



Breadth of the body . . , . 5 mm.' 



Breadth of the head lobe . . 6 mm. 



Breadth of the ambulacral surface . , 2 mm. 

 Position of the mouth from anterior 



end . . . . ,28 mm. 



Position of the genital opening not visible. 



The colour of the dorsal surface is a very dark brown ; three 

 longitudinal black lines are present, a median thin line reaching to 

 the ' neck ' and a pair of broader lateral lines at the edge of the 

 body. These laterals are continued round the contour of the head 

 a little removed from the edge and thickest near the lappets. On 

 the head and alongside the lateral bands is a black mottling. 



Ventrall^^, the colour is a warm brown at the outer edge, 

 gradualh'' becoming paler as the ambulacral surface is reached ; 

 the latter is pale with a brown central line throughout its length, 

 and it ends abruptly at the ' neck.' The under side of the head is 

 darker than the rest of the ventral surface.

 One specimen only of this planarian was found by Dr. Gravely 

 at Pattipola, Cejdon. Its measurements are : — 



Length of the body . . • • 45 ^i"^- 

 Breadth of the body . . • • 5 mm. 

 Breadth of ambulacral surface, about 75 mm. 

 Position of mouth from anterior end 23 mm. 

 Position of genital opening from an- 

 terior end . . . . • • 31 mm. 



The ground colour of both the dorsal and ventral sides must, 

 strictly speaking, be regarded as a warm brown with heavy black 

 mottlings on the dorsal surface. The mottling, however, is so 

 dense as to make the dorsal colouring more easily described 

 as black with irregular small brown splashes; these markings are 

 dendritic, with a tendency to parallel arrangement with numerous 

 cross connections. Extending from one extremity to the other is 

 a median thin brown line, that is, a narrow portion of the ground 

 colour uninterrupted by black pigment. The black marking is 

 practically continuous on each side of the median stripe and also at 

 each side of the body where the colouring of the dorsal and ventral 

 surfaces is sharply marked off. No eyes can be distinguished. 



The ambulacral surface is pale and narrow, about one-fifth the 

 width of the bod}^, extending to both extremities ; it is grooved 

 throughout its length, with a darker pigment at the bottom of the
