I Tab. — Banks of the river Attaran, near Moulmain. I have never seen 
this species. The figure in the Conohologia Indioa is, I believe, taken from 
Mr. Benson’s original specimen ; I have therefore given a copy reduced to 
the natural size. 
17. Claus ilia oVata, sp. nov. 
Testa vix subrimata, elongato-ovata, pwpiformis, intense rufo-ferruginea, 
regulariter confertimque striata ; spira tumida, apice convexo, sutura parum 
impressa. Anfr. 5'5 convexiasculi, primi rapide accrescentes, antepenultimus 
maximus, penultimus vix minor, ultimus ad basin rotundatus. Apertura 
auriformis, fere verticalis, juxta anfractum penultimum repanda, lamella 
swpera acuta, antice validiore, fere verticali, infera stricta ; lunella nulla, 
plicis palatalibus 7, supera producta, in fauce apertura; conspicua, sutura 
parallela, sccunda curvata, cateris brevibus obliquis. Long. 19, diam. 7 mm. 
Apert, oblique 6 longa, 4'5 lata. 
LLab. Ad Nattoung , juxta ripam Attaran fluminis, baud procul a 
Moulmain in Burma. 
This is a fourth species of this little group. It is more ovate than C. 
Bhilippiana and C. vespa, smaller and less tumid than C. bulbus. 
Section Y. — ?Nenia II. and A. Adams. Shell elongate, mouth entire- 
ly free from the last whorl, and broadly expanded, both the lamella: of the 
aperture on the parietal margin and close together, subcolumellar lamina 
large and not concealed by the columellar, a large lunule and one or two 
parietal plaits above it. 
This group includes one species from British Barma, and one ( 0 '. tuba* 
Hanley) from the Shan States of Upper Barma, outside of the British terri- 
tories. It appears to differ from the South American forms which compose 
the subgenus JSTenia in the possession of a lunule, but I have no sufficient 
means of comparison, and in other respects some of the Neotropical forms 
closely resemble those of Barma.

Hah. — Near Tonghii in the mountains between Pegu and Martaban. 
The lamella: of the aperture are as above described. Those of O. tuba 
are precisely similar. 
* Ann. and Mag. Nat. Hist May, 1868, Ser. 4, ol. I, p. 313. By mistake, in 
the Conclwlogia Indica, the Proceedings of the Zoological Society are quoted as the 
work in which this species was described.
