pulmonary veins (the right one somewhat smaller), the venation of the lung is rather 
indistinct. 
Exteriorly the animal has a foot with a mucus pore, surmounted by a small 
papilla (no horn), a sole longitudinally divided into three equal portions, and two 
epipodial furrows running all along the sides of the foot. The lobes of the mantle

O. F. v. Mortitenporrr (1901) expresses a doubt whether HEDLEY’s S. anthro- 
pophagorum is a real Sitala. He says (p. 110): »Konchyliologisch ist sie ohne jede 
Frage eine Coneuplecta und die Beschreibung der Weichteile ist so durftig, dass sich 
darauf keine sicheren Schliisse basiren lassen». The examination of the present spe- 
cies and a comparison with HepLey’s and GopWIN-AUsTEN’s descriptions, however, 
seems to me to remove all doubts as to its generic classification.
