SHUMARDIA Bill., 1862; Pal. Foss., vol. 1, p. 92. Type, Shumardia granu- 

 losa Bill., from Point Levis, Quebec. 



This generic name suggested for a minute Trilobite includes a speci- 

 men having an expanding glabella, with two anterior side nodules, 

 similar to those of Battus pusillus Sars, the genus being allied to 

 Agnostus, differing therefrom in having a regularly ribbed py- 

 gidium, similar to that of an Asaphus. Comparing Shumardia 

 granulosa with Conophrys salopiensis Call. (Quart. Jour. Geol. Soc. 

 London, vol. 33, p. 667, pi. 12, fig. 7), which Brogger (Sil. Etagen 

 2 und 3, p. 125) refers to as a synonym to Battus pusillus, we find 

 a similar characteristic in the glabella. The pygidium of Shu- 

 mardia granulosa has however a more semi-oval form, with a 

 greater number of axis rings and an additional number of ribs 

 on the side lobes.
