' Gmelin refers to the figure by Chemnitz in Conchylien Cabinet, VI. This figure 

 is probably a light-colored hatavus. 



-Fig. 3 is certainly hatavus, and figs. 1 and 2 may be. 



^ Maton and Rackett do not figure their species, but refer to several figures. The 

 first is in Ginanui, Opere Postume, 1755, pi. iv, fig. 17. This work I have not seen. 

 The figures referred to in Schroter's Flussconchylieu, in Chemnitz, and the Encyclo- 

 pedie Methodique (pi. 248, fig. 3) are Avhat we understand as U. hatavus, the latter 

 being the one cited by Lamarck. 



■'Lamarck does not figure his species, but refers to plate ccxlviii, fig. 3, iu the 

 Encyclopedic Methodique, which is the species commonly known as Unio hatavus.
