which is practically preoccupied, and to retain the 

 original specific name. In other words it is desired that 

 the genus and species in future be called SteganoUadas 

 Canadensis instead of Astrocystitcs Caiiadensis.

Addendum to Note on Nova Scotia Carboniferous 

 Entomostraga in Number for January, 1897. 



Since the above note was printed, I have learned from 

 Prof. T. Eupert Jones that he and his colleague, Mr. 

 Kirkby, have recognized in specimens sent by me from 

 Smelt Brook, north of New Glasgow, on the East Eiver of 

 Pictou, in addition to Carhonia Bairdiodes, two additional 



species, viz., C. fahidina, Jones 

 and Kirkby, which is very com- 

 mon in most parts of the Coal 

 Formation of Nova Scotia and 

 Pj^ jq Cape Breton, and C. Ranldniana, 



C. Kankiniana. Fig. 10, a British Coal Formation 



.species, not previously recognized in Nova Scotia, where 

 it may have been overlooked owing to its strong resem- 

 blance to some forms of C. falulina. 



I mentioned with some doubt the specimens of Estheria 

 Dawsoni from the supposed Lower Carboniferous Red 

 Shales of the East Branch of the East River, but Prof. 

 Jones confirms my identification of them, so that we may 

 now hold this species as characteristic of the Lower 

 (Jarboniferous of Nova Scotia ; as it occurs in that 

 formation in localities so widely separated as Lower 

 Horton, Five Islands in Colchester, and Pictou County. 

 The Pictou specimens are, however, of small size, and 

 in the form of custs.
