Its characters agree closely with v. Graff's specimens collected 

 by M. vSarasin in 1883 in Ceylon. It is only half the size of the 

 largest of those described by v. Graff, measuring about 36 mm. in 

 length, and is unfortunately broken into two pieces. The upper 

 side is brownish with a paler area along each side of the mid- dorsal 

 line ; the characteristically narrow ambulacral surface extends to 

 the extreme anterior end round which are the fairly numerous 

 eyes.

Historically, the most interesting land planarian collected in 

 India is B. smithi, since it was the first described from this country 

 with any degree of_certainty. The other few mentioned previous 

 to 1914 were all vaguely described, and the accounts are practically 

 useless. However, though he did not figure B. smithi, v. Graff 

 describes it in his monograph and I have myself examined the 

 specimen in the British Museum. 



The species has, I believe, been found at least four times 

 since ; in its original home by Lord Carmichael and Dr. Gravely at 

 Darjiling, and once by Major Bennett at Lebong in the same district. 



The British Museum specimen measures 60 mm. in length, but 

 the specimens found since are somewhat smaller ; the measure- 

 ments of the largest complete specimen are : — 



Length of the body 



Breadth of the body . . 



Breadth of the head lobe 



Breadth of the ambulacral surface . . 



Thickness of the body 



Position of the mouth from the an- 

 terior end . . . , . . 24 mm. 



Position of the genital opening from 



the anterior end . . . . 36 mm. 



The specimen from Lebong is much larger, though incomplete, 

 and is probably longer than the British Museum specimen. 



The dorsal colour is variable ; the deeper layers of the skin 

 contain a bluish- black pigment which is usually masked by a 

 brown colour on the surface closely resembling a mucus, and which 

 is undoubtedly more pronounced in spirit preserved specimens. 

 Thus there may be a predominence of one or the other -of these 

 colours and frequently a somewhat patchy appearance is shown. 

 The best preserved specimen is distinctly dark, mostly bluish- 

 black, but paler on the head. The eyes form a diffuse black rim 

 to the edge of the head lobe. 



Ventrally, the colour is definitely characteristic ; it is light 

 brown except for the ambulacral surface which, along the centre, is 

 creamish brown, while each side has a bluish-green tinge.
