Dr. Ulrich describes from the Niagara formation at Osgood, Iiid., under the name of 

 Crtlyinmene ntisulti n. sp., a snouted trilobite of a very large size, which resembles 

 Calymmene Niagorens'is Hall. This specimen ^vas published in the Jour. Cincinnati 

 Soc. Nat. Hist, vol. 2, No. 3, October, 1879, p. 131, figs. 1, 2 and 3. The Harvard Li- 

 brary did not receive this number until Feb. 19th, 18S0, or about the time of its probable 

 publication. About this time, in the Amer. Jour. Sci. for December, 1879, a species was 

 described by Vogdes as Calymmene ro.slrafa from the Clinton Group of Georgia Catoosa 

 Station. These forms are very closely related to New York specimens, which are not 

 (|uite so large, and the end of the snout is not so pointed as the published figures would 

 indicate. 



Dr. Berjoron, Bull. Soc. Cieol. de France, 3d ser., vol. xviii, 1890, p. 365, pi. v, places 

 similar species under a new genus. Describing under it Calymmenella Boissrli n. sp. and 

 n. genus. The glabella is short and rounded in front, having three furrows, of which 

 the last two are well marked. 'I'he specimen is somewhat like Calymmr/ie mammillata 

 Hall, from the Niagara group in Wisconsin.

The author, on p. 272, places Enrr'nnints ornalus Hall with E. The.uhi Foerste. He 

 was in doubt regarding the Ohio specimen referred by Hall and Whitfield to E. 

 ornalus, on account of its larger size and its higher geological position.

The author describes Lfochilina panolensis, Beyrichia lata-lriplicata. He also re- 

 marks that Prof. Hall, in Palaeontology of New York, vol. 2, p. 301, published descrip- 

 tions of a species of Bollia and of a species of Beyrichia under the same name Bey- 

 nclna lata, erroneously regarding these distinct species as opposite valves of the same 

 species. Beyrichia is described first, but on Plate A 66 the Bollia is figured first. 



The author refers to Bollia lata Hall's fig. 10b, and to Beyrichia lata Hall's figs. 10.
