At Akoutoung I also found A. humilis, W. Blanf., and at the same 

 place, at Thondoung and at Yenandoung, two hills about 20 miles 

 further south, I found a variety of A. Ingrami, W. Blanf., rather 

 larger than the type from Tongoop in Arakan, and measuring 7 

 millem. in the larger diameter. 



Another form of the same shell, with a less distinct subangulation 

 of the periphery, and rather closer sculpture on the upper whorls, 

 occurred at Moditoung, on the Prome and Tongoop road, with 

 A. graphic us, "W. Blanf, A. succineus, W. Blanf., neither of which 

 has been found elsewhere, and one form of A. vestitus, W. Blanf. : 

 A. niticlus, W. Blanf. and A. polygonoma, W. Blanf., were first found 

 on the same road, but nearer to Tongoop. The latter I afterwards 

 obtained in two or three places south of Bassein, the specimens being 

 a little larger (6 and 5 millem. in their two diameters) than those first 

 found. A. vestitus has only been found in the Arakan hills on the 

 confines of the Henzada and Prome districts. 



Adding to these the two new species above described, A. politus 

 from near Cape Negrais, and A. glaber from Akyab, we have 14 

 species described from Ava, Pegu, and Arakan, besides 3 more from 

 Mohnein and Tenasserim, altogether nearly half the known species of 

 the genus. 



Pupina. 

 A species of Pupina occurs at Thayet Myo, Prome, Akoutoung, &c, 

 closely resembling P. artata, Bens, from Molmein, but rather stouter 

 in form and with a somewhat thicker peristome, which is frequently 

 but not always orange in colour, instead of wbite. These differences 

 do not appear, however, to warrant specific distinction, especially as 

 there is much variation in the form of typical specimens of P. artata. 

 A variety from Ava is closer to the type. A small form, probably 

 another variety, occurred upon the Arakan bills near Prome. It is 

 only 4J millem. long, but the specimens are unfortunately not quite 

 fresh. My own specimens of P. artata from Molmein are but 6 

 millem. long. The operculum in fresh specimens is horny, not 

 testaceous, the white appearance being produced by weathering, and 

 I suspect the apparently paucispiral character to be due to the rapid 

 increase of the interior whorls, which rest one upon the other, as in
