8 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 97 



This species characterizes Honey Creek Hmestone of Oklahoma. 

 The Texas form, from the sHghtly older Lion Mountain sandstone, 

 formerly referred to L. nina, is a larger brachiopod. 



Upper Cambrian, Honey Creek; (loc. gr) 15 miles northwest of 

 Fort Sill, and other localities in Oklahoma. 



Holotypc and paratypes. — U.S.N.M. no. 51643. 



Lingulella turneri, n. sp. 



Lingiilclla (Liiigitlcpis) acimiiiwfa Walcott (part), U. S. Geol. Surv. Mon. 

 SI, p. 545, pi. 34, figs. 3a-d, 1912. 



This form was apparently placed in Lingulepis acuminata be- 

 cause L. ncvadensis was included with it. 



L. turneri is characterized by an average size for the ventral valve, 

 about 9 mm long and 6 mm wide. There is a tendency toward flatten- 

 ing of the front marginal outline. 



Upper Cambrian, Emigrant; (Iocs, /x, /z) 2^ miles southeast of 

 Benders Pass, Silver Peak Range, Nevada. 



Cotypes. — U.S.N.M. nos. 56967, 51884. 



LINGULEPIS Hall, 1863 



Lingulepis burnetensis, n. sp. 



LlngiileUa (Lingulepis) oaniiiiiata Walcott (part), U. S. Geol. Surv. Mon. 

 51. P- 545, pl- 42, figs, ik-n, 1912. 



This species is smaller than either Lingidella hridgei or Lingulepis 

 llanoensis. Compared with the latter L. burnetensis has about the 

 same width, but the shell is shorter and the ventral valve tapers less 

 evenly. One specimen 9 mm long is 6 mm wide. 



Upper Cambrian, Wilberns ; (loc. 70) Baldy Mountain, Morgans 

 Creek, 8 miles northwest of Burnet, Texas. 



Cotypes.— [J.S.'HM. no. 51891. 



Lingulepis llanoensis, n. sp. 



Lingulella (Lingulepis) acuminata Walcott (part), U. S. Geol. Surv. Mon. 

 51, P- 545, pl- 42, fig. I, o, 1912. 



Walcott figured only the interior of the dorsal valve, but a very 

 fine example of the ventral valve lies against it. This species is 

 slender, a ventral valve 12 mm long being only about 6 mm wide. The 

 ventral valve tapers at a nearly even rate to the apex. 



Upper Cambrian, Wilberns; (loc. 14b) Cold Creek, 2 miles south 

 of the San Saba county line, Llano County, Texas. 



Holotype and paratypes. — U.S.N.M. no. 51892.
