MOLLtrSCA OF INDIA. 



411 



red-lipped variety of A. ui-mtla (Diori/x lahrirnbldam, see p. 430) 

 and several specimens of A. rkhiliofeni. The shells slightly vary in 

 the height of the spire, but all are" of exactly the same character." 

 This supposed extension of Burmese species to the N.E. Hima- 

 laya and Khasi Hills is not established, the D. urnula mentioned 

 is probably not like the type. 



Alyc^us notus, n. sp. (Plate CLV. fig. 12.) 



LocaliUi. Fort Btedmau, Burma. No. 3065 G.-A. Coll., B.M. 

 {Colonel R. Wooclthorpe). 



Shell umbilicated, depressedly conoid, rather solid ; sculpture on 

 upper whorls fine very close costulation, becoming more distant as 

 the end of the sutural tube is reached, it is then particularly fine 

 and close, smooth behind aperture ; colour stony white, some have 

 a pink apex ; spire low, apex blunt : suture impressed, the sutural 

 tube rather short ; whorls 4, rounded, constriction slight near base 

 of sutural tube, then swelling very slightly forward to the peri- 

 stome ; aperture ovately circular ; peristome double, thick, inner 

 continuous, plain, outer reflected; operculum closely spiral, 

 brown. 



Size: raaj. diam. 3-0; alt. axis 1-5 mm. 



Like armillatus, but much larger. 



Alyc^iius ochraceus, G.-A. 



Moll. lud. vol. ii. 1897, p. 3, pi. Ixiii. figs. 7, 7 a, 7 b. 



Ruby Mines Dist., Upper Burma. Nq. £684 B.M. Type. 



Alyc.^us omissus, n. sp. (Plate CLV. fig. 13.) 



LocaUtif. Siam and Shan boundary. 2 specimens, 1228 G.-A. 

 Coll., B.M. (Colonel B. Wooclthorpe, R.E.). 



Shell umbilicated, depressedly conoid, strong ; sculpture rather 

 distant costulation up to the end of the sutural tube, which 

 becomes closer towards the apex and less pronounced, next the 

 tube it is very close and regular ; colour bleached ; spire depressed, 

 apex small ; suture impressed, the sutural tube moderately long ; 

 whorls 4, the last is smooth in front of the sutural tube, the 

 interval to the aperture has a slight rise in the middle ; aperture 

 circular; peristome thick, double, the outer lip well reflected— 

 within in the lower outer margin there are a few close-set teeth- 

 like crenulations, recalling what is to be seen in A. sculptilis on 

 a far larger scale. 



Size: maj. diam. 2-8 ; alt. axis 1-1 mm. 



These specimens were received many years ago, at the time 

 Colonel Woodthorpe was making the first survey of the country so 

 far east as Kengtung and the Mekong River; he brought back 

 many interesting new shells, most of which have, I am sorry to 

 say, been undetermined by me. Evidently very much more 

 collecting remains to be done in that part of our eastern possessions.
