Aphelocona coenerea 4 18 Apr (1957) from slightly left of midventral line around right side of proventriculus with an apex on the dorsal surface. On the right it does not lie on side of gizzard but there are some intestinal folds between these two organs. Proventriculus: It was necessary to cut open the lower part of the oesophagus, proventriculus, and gizzard to set exact delimitations. Opened down left side. Prov. is little more than expansion of oesophagus - not muscular. Fields of oesophagus extend part way into prov., but lower part of prov. lining is smooth. Prov. measures 10mm. in length. Gizzard: Measures 26 x 20 x 11 mm., longest dimensions. From prov. curves ventrally, so prov. opens on dorsal side, top. Lined with horny material outside of which is a fairly thick layer of muscle. Muscle layer is thicker anterior and posterior, thinner on the sides. Gizzard is 7mm thick at posterior end, 6mm at anterior end., average 2mm. on sides. Opening to intestine is far anterior or at right wall, near proventriculus. Contains a few small stones, a large number of seeds, but most material is so broken up to be unrecognizable. Except for one fat + one intestinal loop, forms entire ventral body surface,
