264 UNCERTAIN SPECIES. 



Pupa anodonta Hedley and Musson, Proe. Linn. Soc. N. S. 

 W. (2), VI, 1891, p. 558, belongs to the genus Heterocyclics 

 Crosse. 



Ptychospira deloplecta Slavik, pi. 32, figs. 14, 15 (Achiv. 

 fur naturw. Landesdurchforschung von Bohmen, i, 1869, Sec- 

 tion II, p. 267, pi. 4, f. 14, 15) is a new genus and species 

 based on a minute shell 2 mm. high, 1 wide, of 4% whorls, 

 described as finely rib-striate with transversely oval aperture, 

 simple, sharp lip, the parietal wall bent in form of an enter- 

 ing fold, the sharp angle of which projects into the cavity of 

 the whorl, the cavity between this parietal fold and the 

 penult whorl is open towards the umbilicus ; in front the fold 

 is truncated and closed by a thin callus. The figures were 

 restored from parts of three broken specimens, and may there- 

 fore be inaccurate. Marly beds of Tuchoric, Czechoslovakia. 



G. Klika agrees with Sandberger in considering this the 

 immature stage of a Pupid shell (Tert. Land- u. Siisswasser- 

 Conch. N.-W. Bohmen, 1891, in Archiv. naturw. Landesdurch- 

 forschung Bohmen, vii, Geol. Abth., p. 98), though it does 

 not appear referable to any known Pupid of the same beds.
