Reported merely from the Philippines by Hidalgo on the authority 

 of Baranda, and so far no definite locality is known, those before me 

 collected by Steere and others bearing the same indefinite label. It 

 is quite a distinct race, though varying widely in size, proportions 

 and solidity. 



2. Group of A . javanicus. 



Large species with coarse wrinkle-striation and usually open 

 umbilicus, the lip reflexed and narrowly recurved at the edge, but 

 never in the least adnate on the back. Either dextral or sinistral. 



The forms vary a good deal, and may eventually all be reduced to 

 subspecies of two or three species. 



a. Lip flatly reflexed, wide, broader at base. inauris, p. 138. 



a 1 . Lip normal, reflexed, and recurved at the edge. 

 b. Shell conspicuously streaked. 



javanicus, p. 140; heerianus, p. 138. 



b l . Shell spirally banded. robustus, p. 139. 



b 1 . Shell unicolored or with one or two varices. 



c. Pale yellow, no varices ; much inflated, the spire short. 



teysmanni, p. 134. 



e 1 . Pale yellow, no varices; a white, crenate band at the 

 appressed suture ; long-conic, solid, appressus, p. 136.
