I cannot but believe that the fine Subulina collected by Mr. Hunger- 

 ford at Buket Pondong is the same which Mr. Nevill mentions from the 

 same locality as a doubtful S. {Opeas) terebralis, Theob., or a n. sp. I 

 have no figure of Theobald's species at my disposal — has it been figured 

 at all ? the Conchologia Indica does not give it — but if the species of 

 the Shan States is really an Ojpeas, it cannot be identical with the Perak 

 form, which decidedly belongs to Subulina. De Morgan's description of 

 his H. tchehelensis is somewhat vague and apparently was taken from 

 immature examples, but, as the dimensions given by him of a specimen 

 having 10 whorls — 23 x 5 mill, agree perfectly with those of some 

 younger specimens in Mr. Hungerford's collection, I think the two forms 

 of different Perak localities may be safely combined.

Mr. de Morgan has founded a new genus for a curious Stenogyra- 

 like shell, which he considers to be related to Bhodea. It may be worth 

 while to translate his description here : — " Shell cylindraceous, striate, 

 dextrorse, numerous whorls, apex obtuse, last whorl much larger than 

 the penultimate, aperture triangular, columellar margin reflected and very 

 prominent [" saillant "], peristome continuous. Differs from the genus 

 Bhodea by the aperture " disposee en cornet " and by the want of a 

 keel." I must confess that I fail to perceive any relation to Bhodea 

 from these remarks. The descriptive notes on the species are meagre 

 also ; it is cylindrical, fragile, horny yellow, has 10 regularly in- 

 creasing whorls very regularly and distinctly striate, the suture is linear 

 and well-marked, the aperture triangular, oblique, peristome thin, not 

 reflected (" non dejete "). Long. 25, diam. of last whorl 4|, long, of 

 aperture 5, lat. 3 mill.
