S. India ; it must therefore have a wide distribution in India 

 and will probably be found in many other districts eventually. 



The following description refers in particular to No. ZEV ^V~ 

 from Bagarkote at an altitude of 3,000 ft. which is the largest 

 specimen. 



Length of the body . . . . 58 mm. 



Greatest breadth of the body . . 9 mm. 



Thickness of the body . . . . 3 mm. 



Breadth of the head lobe . . 6 mm. 



Breadth of the ambulacral surface . . 3 mm. 

 Position of mouth from the anterior 



end . . . . . . 24 mm. 



Position of the genital opening from 



the anterior end . . • • 33 mm. 



The ground colour of the dorsal surface is a warm rusty brown 

 with three longitudinal dark stripes, a median and a pair of 

 laterals. The median stripe is prominent and jet black, extending 

 from the extreme anterior to the posterior extremity, and widening 

 slightly above the pharyngeal and genital regions. The lateral 

 stripes are of diffuse black pigment and broader than the median, 

 extending from the ' neck ' to the posterior end of the body. The 

 eyes are closely packed to form a thin jet black line round 

 the edge of the head lobe ; they are also found distributed general] y 

 over the head region. 



The ventral surface, except for the creeping area, is a dull 

 rusty brown with a greyish outer edge along the whole length but 

 not sharply marked off from the brown. The ambulacral surface 

 is purplish- grey, the middle being raised, into a ridge ; the mouth 

 and genital openings are prominent and from them respectively 

 protrude the frilled pharynx and genital organ. 



The other specimen differs in minor particulars. 



No. ZEV '^'V" " from near the Forest Tramway in Cochin State 

 at an altitude of 300 ft. is 17 mm. long and its dorsal colouring is 

 of the same pattern as that of the specimen described above, with 

 the following exceptions : The lateral bands are jet black and not 

 diffused ; the median line ends in a club-shaped expansion on the 

 head, which is otherwise pale. These differences are such as may 

 be met with in young specimens ; it is characteristic of land plana- 

 rians that stripes tend to disappear with age, a feature constantly 

 illustrated in the case of Bipalium diana.

Indian Museum Collection No. ZEV "'V" B. 



One specimen of this Geoplanid was procured along with 

 Bipalium brtinneus at Bagarkote in Kumaon, Western Himalayas, 

 at an altitude of 3,000 ft,, in June 1914. 



The animal is small and very blunt at each end ; in transverse 

 section it is almost circular. Its measurements are : —
