concave curvature of the frontal limb and border. It has very little 

 in common with Lonchocephalus chippewaensis, the genotype of the 

 genus Lonchocephalus, under which all the species now included 

 under Saratogia have been included. 



The species now referred to Saratogia are : 



Saratogia arses, n. sp. (pi. 35, figs. 4, /{a-b). 



Saratogia aruno, n. sp. (pi. 35, figs. 5, Sa-^)- 



Saratogia calcifcra (Walcott) (pi. ZZ, figs. 6, 6a). 



Saratogia hamulus (Owen) [Sixteenth Ann. Rept. New York State Cab. Nat. 



Hist., 1863, pi. 7, figs. 43, 44]. 

 Saratogia hera, n. sp. (pi. 35, figs. 3, 30-6). 

 Saratogia tellus (Walcott) [Research in China, Carnegie Institution of 



Washington, No. 3, Vol. 54, 1913, pi. 14, fig. i]. 

 Saratogia volux, n. sp. (pi. 34, fig. 3). 

 Saratogia wisconsensis (Owen) (pi. 34, figs. 5, 50-^) [See Hall, Sixteenth 



Ann, Rept. New York State Cab. Nat. Hist., 1863, pi. 7, figs. 39-41 ; pi. 8, 



figs. 22, 23, 24, 27, 28. Walcott]. 



The occurrence of Saratogia hamulus (Owen) in the Yellowstone 

 National Park is quite probable, but not proven by reliable speci- 

 mens.^ 



SARATOGIA ARSES, new species 

 Plate 35, figs. 4, 4a-& 



This is a small species represented by a cranidium about 4 mm. 

 in length exclusive of the occipital spine. It differs from the 

 somewhat similar species 5". aruno (pi. 35, fig. 5) and .S*. wisconsen- 

 sis (pi. 34, fig. 5) in form of glabella and in the greater convexity 

 of the glabella. The outer surface of the test appears to be nearly 

 smooth. 



The occurrence of this species in one of the thin gray limestone 

 layers in the Nolichucky shale is interesting, as it serves to connect 

 the Upper Cambrian fauna of the Appalachian region and that of 

 the upper Mississippian area. 



Formation and locality. — Upper Cambrian: (173) Nolichucky 

 formation; Maryville, Blount County, Tennessee. 



SARATOGIA ARUNO, new species 



Plate 35, figs. 5, 5a-& 



This small species is represented by a cranidium that is very much 



like that of Saratogia wisconsensis (pi. 34, fig. 5), and it may be that 



with more and better specimens it will be decided that the two are 



specifically identical.
