PROCEEDINGS OF THE ACADEMY OF 



Fig. 40, does not give a recognizable outline of typical Pal. rufa, of the size 

 of the figure. 



Fig. 43, page 27, refers to a species of shell found in the Ohio Canal at 

 Columbus, Ohio. Other shells of a similar form at maturity, from other locali- 

 ties have been confounded with this as Pal. obesa ; but later investigations 

 referring to the embryonic yourag and other specimens of various sizes would 

 warrant the conclusion that they were distinct. This shell stands related on 

 one hand to inteyra and ponderosa, and on the other to Pal. regularis, Lea. 

 The young shells nearly but not quite resemble Mr. Lea's types of regularis. 



Fig. 44. Pal. genicula, is more nearly allied to Integra than to any other 

 known form. 



Mr. Binney has given a figure of the lingual dentition of specimens of Pal. 

 iniegra on page 29. It is to be regretted that minute comparisons were not 

 made between those of Integra with the teeth of rufa from the specimens of 

 the two species which were furnished him by the writer for that purpose. 



Mr. Binney is also unfortunate in his treatment of Pal. coarctata, Lea. It 

 certainly cannot short of doing violence to the subject be made to embrace 

 Pal. exilis, Anth., to which P. compressa is here submitted as a synonym.
