have two purple-brown bands, one above, the other below the periph- 

 ery, and a white lip. The lower of these two bands is homologous 

 with the upper one of the Tamanka shells. These several forms seem 

 to be closely connected with one another, and not separable as species. 



A. trifasciatus "I should term a low country species. I have 

 taken it about Galle and Matura." " Essentially a tree species." 

 (Layard.} 



Var. rufopictus (Benson). PI. 1, fig. 9. Shell smaller, alt. 19- 

 23 mm., usually two- or three-banded below, spotted or dotted with 

 corneous -brown on a pale brown ground, the first two whorls uniform. 

 Surface of spire densely punctate. 



Ceylon: Kandy, 1,500 ft. elev. (O. Collett); Akurambode (Lay- 

 ard.) 



Distinguished chiefly by its copious maculation. A specimen from 

 Kandy before me is more conic than that figured from Akurambode, 

 with the bands nearly obsolete. 



A. CEYLANICUS (Pfciffer). PI. 1, fig. 7. 



Shell openly perforate, ovate-conic, solid, obliquely striatulate, 

 somewhat shining, white or fleshy-brown ; spire conic, rather acute ; 

 whorls 6, flattened, the last about three-sevenths the length of the 

 shell ; columella slightly arcuate. Aperture truncate-oval ; peristome 

 widely expanded, a little reflexed, the columellar margin dilated, 

 reflexed, spreading. Length 27, diam. 14, aperture inside 11 mill, 

 long (/yr.). Ceylon (Templeton, in Cuming coll.).

This species differs from A. albizonatus and its varieties in the 

 rounded last whorl, a keel being absent. Pfeiffer's dimensions agree 

 with a specimen before me if his method of measuring the diameter 

 be followed. Including the outer lip, the shell would be wider, 

 length 26J, diam. 15^ mill. In my opinion the shells figured for 

 ceylanicus in the Conchologia Indica are forms of A. trifasciatus, and 

 not Pfeiffer's species. Kobelt has copied these figures in the Con- 

 chylien Cabinet, pi. 103, f. 5, 6. 



Mr. E. R. Sykes (in litt.} writes that he believes ceylanicus and
