 p. 504, a figure (120é) of Heliol. megastoma, which, however, seems to belong 

 to Hel. porosus. The description also contradicts this figure as there is stated that 

 »die 12 Sternlamellen wenig entwickelt». Moreover it is quite impossible to coordinate 

 the longitudinal section in fig. 120(.', with the transverso section in b, as of necessity 

 the well developed septa must be seen in the former.
