430 LAND AND FEESHWATKR 



In this specimen there had been some check to the dcrelopmenf of 

 the peristome, shown by a cicatrix (fig. x, x'), followed b}' a similar 

 check to the secretion of shelly matter on the circular edge of the 

 tube, which is contracted for a short distance and then resumes its 

 original gauge. "Within the aperture, a small hole may be seen 

 Avhere the fleshy tube from the branchial chamber enters the shelly 

 external one.

LocaJitij. I^ear Moulmein ( Wm. Theobald). 



This species is in the Indian Museum, Calcutta, and is noted in 

 Kevill's Hand-list, No, 22, p. 292, as a new species, but he did not 

 name it. It is recorded as from Khargan, Ataran Valley, coll. 

 AV. Theobald, Esq., 4 spec, and Phaboo, coll. Dr. Hungerford, 

 2 specimens. It is the red-lipped species briefly alluded to by 

 Theobald and Stoliczka in the Journ. Asiat. iSoc. Bengal, 1872, 

 p. 330. GeofFrej' Nevill in his private copy of the Hand-list, notes 

 this, and he had received the species from Theobald himself. Ihree 

 specimens are included with the above, marked Salween, but the 

 coUe iter's name is not given nor the exact locality, they are slightly 

 smfJler than the type I have flgured and described from Moulmein.
