Although there are no true Gryphasas in our Tertiary, the general con- 

 fusion in the literature in regard to the type of this group, and its bearing 

 on the nomenclature of the genus Ostrea seem to make it desirable to clear 

 up the synonymy. 



Gryphcea was described as a genus by Lamarck in 1801, no type being 

 selected, but a number of species cited, part of which had been figured in 

 other works, to which figures Lamarck applied names ; others were unde- 

 scribed, and these names were, of course, iiomitia niida until such time as 

 they might be habilitated. The figures to which Lamarck gave names were to 

 be found in the Encyclopedic Methodique of Bruguiere, pi. i8g; Bourget, 

 Mem. hist. nat. petr., pi. 14, 15 ; and Knorr, Naturg. Verst., ii., part i, pi. 20, 

 60, and 62. The first two columns of the following table show the original 

 nomenclature of Lamarck and the figures upon which it was based. The 

 names opposite the first in the third column show the equivalent names, and 

 the fourth column references for the same fossils, used by Lamarck in 18 19 

 when the manuscript species of the first list were first described. Only one 

 reference is given in the second column for each of the first list of names, and 

 preference has been given to the plate of the Encyclopedic, which has by far 

 the most recognizable figures. 



As Lamarck selected no type, the type must be sought from the first 

 reviser. This was Bosc, in the following year, who cites the described species 

 and figures as an example the G. arcuata, which he refers to the Anoiina 

 gryphtis of Linne. 



The next author to treat the group was Roissy, who cites as examples 

 G. siiborbiailata and G. arcuata, and figures the latter to illustrate the genus.
