MOLLUSCA OF INDIA, 3 



Altctius ocHRACEirs, Godwin-Austen. (Plate LXIII. figs. 7, 

 la, 7b.) 



AJycceus ochraceus, G.-A. P. Z. S. 1 893, i?. 594. 



Locality. Ruby Mines District, Upper Burmah ( W. Doherty). 



Original description : — " Shell sub-depressedly turbinate ; sculp- 

 ture rather strong ribbing on the swollen part of the last whorl, on 

 the apical whorls it is close and fine : colour ochre ; spire somewhat 

 flattened, apex blunt ; suture deep ; whorls 4, the last moderately 

 swollen ; sharp constriction in front of sutural tube, followed by a 

 strong ridge which is contiguous to the crenulate peristome ; aper- 

 ture circular, suboblique ; peristome strongly crenulated, double ; 

 operculum horny, a large central excavated circular space, sur- 

 rounded by a pale ring, well marked, rising above to the marginal 

 portion. 



" Size : maj. diam. 4*5 ; alt. axis 1*5 mm. 



" The nearest known species allied to this is A. crenatus, of the 

 Khasi Hills, but the ridge behind the aperture in this last lies 

 further back with a short interval ; the peristome is not so strongly 

 crenulate. A. plectoclieilus of Darjiling is a much smaller form." 



ALiciEUs DOHERTYi, Godwin-Austcu. (Plate LXIII. figs. 3, 3 a.) 



Alyaeus dohertyi, G.-A. P. Z. S. 1893, p. 595. 



Locality. Momeit, Burmah (IF. Doherty, in coll. Aldrich). 



Orif/inal description : — " Shell globosely turbinate, solid, not 

 umbilioated ; sculpture regular distant sharp costulatiou, closer and 

 fine near the sutural tube ; colour stone, with pink apex ; spire 

 rather high, conoid, rounded, apex blunt ; suture impressed, the 

 tube fine, rather long; whorls 4|, the last swollen, constricted with 

 a rounded ridge midway between the sutural tube and the peristome ; 

 aperture expanded, ovate ; peristome double, fine sharp crenulatious 

 on the outer margin, rounded on the inner. 



" Size : maj. diam. 3*25 ; alt. axis 2-8 mm. 



" This is quite a new form, partaking in the constriction and 

 peristome of the characters of A. plectocheihis, crenatus, &c. Momeit 

 lies N.N.E. of Mandalaj', about midway between it and Bhamo and 

 further east than Mogok in the Ruby Mine District." 



The single specimen and type figured has been sent to I^[r. T. H. 

 Aldrich, who kindly forwarded to me all the shells collected by 

 Mr. Dohei'ty in Burmah and Assam.

Alycoius ruhinns, G.-A. P. Z. S. 1893, p. 594. 



Locality. Ruby Mines District, Upper Burmah ( W. Doherty, in 

 coll. Godwin-Austen). 



Original description : — " Shell globosely turbinate, closely um- 

 bilicated, of thin texture, the last whorl not much swollen ; sculp- 

 ture very tine close ribbing adjacent to the sutural tube, rest of 

 shell smooth, with distant fine striae ; colour olivaceous ochre ; spire
