Parietal armature consisting of a simple, stout, curved, ob- 

 liquely ascending, transverse plate. The palatal armature is com- 

 posed of six spiral folds : the first short, horizontal, near the 

 upper suture ; the next four longer and stouter, their posterior 

 terminations notched ; the second horizontal ; the third, fourth and 

 fifth obliquely descending backwards ; the sixth short, horizontal, 

 near the lower suture ; between the posterior ends of the fifth and 

 sixth folds occurs a slight denticle. 



Major diam. 14, minor 12 mm.; alt. 6 mm. 



Hab.— Luyor Peak, Abor Hills, alt. 7200 ft. Lat. 28°45' : 

 Long. 95°45'.

When in 1899 the writer established the section Smicola 

 (Science Gossip, new series, VI, p. 148) it was believed to be con- 

 fined within the limits of the Chinese Empire, Two species be- 

 longing to this group were subsequently discovered in Tonkin 

 (P. emigrans and P. fruhstorferi), while a third (P. hirasei) was 

 taken in the Loo Choo Group, but, until the present species 

 was found, no member of the section was known to occur to the 

 south of the Himalaj'as. P. habhagei, therefore, constitutes a verj^ 

 interesting and important addition to the Indian fauna. It 

 appears to be nearest in affinity to P. pulvinaris , which, however, 

 possesses 7 palatal folds and is not, like the present species, decus- 

 sated by spirals. The name of Major-GeneralBabbage, who led an 

 expedition against the Abor tribes in 1847, suggested by Lt- 

 Col. God win- Austen, is associated with this new species.
