The exact locality where I procured this species I do not know, beyond 

 that it was near the Salween. It is interesting as the simplest form of the 

 group to which it belongs, having no teeth and rather feeble striation. Its 

 habit, however, is quite that of a Sesara, and it comes from what is almost 

 the headquarters of the group in Burmah.

A few dead examples of this handsome and evidently arboreal species 

 have reached me through the kindness of Mr. Bourdillon, after whom I 

 have named it, and to whom I am indebted for a small collection of shells 

 from the same locality. Among these were Gyclophorus Niligiricus, Catau- 

 lus Calcadensis, Myxostoma deplanatum, Micraulax scabra n. sp., Ditropis 

 planorbis,JHychopoma Jiirsutum,the recently described Hemiplecta Beddomei, 

 Hotula indica (a large form of 28 mills and a small stout form of 17 

 mills), It. Shiplagi, Sitala apicata, a single reversed arboreal Helix of the 

 albizonata type {Qeotroclms Calcadensis) , a Glessula which seems a mere 

 variety of G. parabilis, a stouter form with more arcuate columella (pro- 

 bably G. DesJiagesiana), and a small species not determined, a Streptaxis, 

 and Hapalus Travankoricus, n. sp.
