A pair of giant garden slugs, though permaphrodies hermaphrodites, behave as if one were male and one were female during the period just preceding, during, and after mating. A description of this behavior, with photographs, is presented, and the possibility of protandrism is suggested.

Two species and four subspecies are new. The presence of Trigonoglossa truncata in the Wisconsin section seems to substantiate the extension of the range of this Pennsylvanian genus into the Middle Devonian as suggested by Girty, and the existence of well-preserved Lingulidiscina in the Milwaukee Formation supports the validity of this genus, previously questioned by Girty. Correlation of the Lake Church formation is obscure because of incomplete collections from localities now inaccessible. However, distinctive Milwaukee Formation species show affinities with Upper Middle Devonian Cedar Valley brachiopods of Iowa, indicating the possibility of a connection between these areas during late Hamilton time.
