Coelospira concava {Leptocmlia concava^ Hall Pal. N. Y., 

 Vol. 3, page 245, plate 38, figs. 1 to 7 ; may be considered a 

 representative of the Russian brachiopod shell Terebratula 

 duhoisii^ De Verneuil (Geol. Russ. pi. 10,) f. 16, but is rounder 

 and more concave in the dorsal valve ; surface wdth 14 to IT 

 striae; concavity, produced by the middle groove widening 

 rapidly from beak to margin, being deep midway. — Specimen 

 876-3a (00, page 237) in Hicks' collections near Big Shanty, 

 McKean county. Pa., was found not in Lower Helderherg^ but 

 in Chemung strata. Hall recognizes a diff*erence between the 

 similar shells in the Lower Helderherg c& Oriskany (see Vol. 3, 

 page tt52) and calls the latter Coelospira {Leptocmlia) dicho- 

 toma ; the Chemung species should perhaps have a difi'erent 

 name. — VI ; VIII g. — See Appendix.

 here on account of its curious 

 beauty, and to excite the 

 curiosity of our collectors; 

 as w^ell as to invite attention 

 to Prof. WinchelPs excellent 

 text books.
