Menomonia texana, n. sp. 



Millardia az'itas Lochman (not Walcott), Journ. Pal., vol. 12, no. i, p. 84, 

 pi. 18, figs. 4-S, 1938. 



This species evidently was referred to M. avitas because it has 

 smaller granules than M. nmgnagranulata. The reference to the Penn- 

 sylvania species cannot stand. M. avitas has a few scattered large 

 granules on the glabella and fixigenes ; the remainder of the cephalon 

 is smooth to finely granulose or ornamented with lines. The eyes of 

 M. avitas are elevated on rather long stalks. This may also have 

 been the case in M. texana as the eyes are broken off. M. texana is 

 further characterized by a long slender glabella and the eyes are 

 rather far forward. 



Upper Cambrian, Cap Mountain ; southwest side Lion Mountain, 

 Highway 29, 9 miles northwest of Burnet, Texas. 



Holotype. — Mount Holyoke Mus. no. 655 ; paratype, no. 656. 



Menomonia lochmanae (Lochman) 



Millardia avitas Lochman, Journ. Pal., vol. 12, no. 5, p. 469, pi. 56, figs. 27, 

 28, 1938. 



This species differs from M. avitas in the more incurved anterior 

 margin and considerably larger fixigenes. 



Upper Cambrian, Petit Jardin ; Cape St. George, Newfoundland. 

 Holotype. — Yale Peabody Mus. no. 15822. 



NORWOODIA Walcott, 1916 



Norwoodia Walcott, Smithsonian Misc. Coll., vol. 64, no. 3, p. 168, 1916. 

 IVhitfieldina Resser, idem, vol. 95, no. 22, p. 27, 1937. 



Just after the 1937 paper appeared, the genus Nonvoodia was re- 

 considered in conjunction with studies in the southern Appalachians. 

 As soon as the extraneous species then in Norwoodia were removed, 

 it became clear that IVhitfieldina is not a valid genus, because its type 

 species is a typical N orzvoodia, contrary to the misleading published 

 figures. 



Norwoodia quadrata (Whitfield) 



Conocephalites qnadratns Whitfield, Ann. Rep. for 1879, Wisconsin Geol. 

 Surv., p. 47, 1880; Geol. Wisconsin, vol. 4, p. 180, pi. i, figs. 15, 16, 1882. 

 IVhitfieldina quadrata Resser, Smithsonian Misc. Coll., vol. 95, no. 22, p. 27, 

 1927.
