Macrochlamys shimangensis, n. sp. 

 (Plate li, figs. 2, 2a). 



Locality. — Abor country {Captain G. F. T. Oakes). 



Shell globosely conoid, perforate, with an epidermis ; sculpture 

 none ; colour dull umber brown ; spire su])conoid, apex bluntly 

 rounded; suture shallow; whorls 5, rather rapidly increasing, the 

 last ample; aperture oval^ subvertical ; peristome thin; colu- 

 mellar margin subvertical, just reflected at umbilicus. 



Size : major diameter 20*25, minor 1725, alt. axis 80 mm. 



This is a close ally of M. bapuensis , but is a much more glo- 

 bose shell, and I have four examples of it. 



Macrochlamys hippocastaneum, n. sp. 



(Plate li, figs. 3, 3a.) 



Locality. — Luyor, Abor country {Capt. G. F. T Oakes, R.E.). 



Shell globosely conoid, finely perforate, polished ; sculpture 

 none, quite smooth and glassy ; colour rich dark chestnut ; spire 

 conic; apex blunt; suture impressed; whorls 5, rather rapidly 

 increasing, rounded on the periphery ; aperture broadly lunate, 

 nearly vertical ; peristome thin ; columellar margin thin, scarcely 

 reflected near umbilicus. 



Size : major diameter 20'0, minor 1775, alt. axis 9*25 mm. 



Only one specimen of this beautiful shell was sent home, it is 

 unlike any I have as yet seen from either Assam or from Burma. 

 It was put up alive, but arrived in a state I could only make out 

 a well-developed right shell lobe and a small left shell lobe. 



Macrochlamys psittacinus, n. sp. 



(Plate li, figs. 6, 6a.) 



Locality. — Abor Hills, only one specimen {Capt. G. F. T. 

 Oakes, R.E.). 



Shell globosely conoid, perforation concealed, smooth, shining ; 

 sculpture fine regular longitudinal striation, stronger near and 

 below the suture ; colour dark olive green ; spire flatly conic ; 

 apex blunt and rounded; suture impressed; whorls 5, the last 

 rounded on the periphery, increasing rather rapidly ; aperture 

 widely lunate, oblique ; peristome thin ; columellar margin oblique, 

 with scarcely an^^ reflection above. 



Size : major diameter 145, minor r2"5, alt. axis 575 mm. 



I have placed this in Macrochlamys as the most likely genus, 

 from the look of the shell. The animal may prove to differ 

 nevertheless. 



Macrochlamys? rotungensis, n. sp. 



(Plate li, figs. 7, ya; pi. liv, figs. 6, 7.) 



Locality.— Rotnn.^^ Abor Hills, spirit specimen. No. 5991
