14 MUSEUM OF COMPARATIVE ZOOLOGY. [Apr. 



part of the vegetation of the Carboniferous age, and perhaps 

 only a small part. In the same deposit, and in the same kind 

 of pebbles, many small animals — Crustacea, Anelides, winged 

 Insects, and even Saurians — have been found of late, all species 

 unknown before in the Coal measure. The Museum has 

 recently made arrangements for obtaining a larger number of 

 specimens from that locality. 



6th. Among the Coal plants of the Museum, a collection 

 worth mentioning for the beauty and large size of its specimens, 

 especially in the genera Sigillariaand Lepidodendron, is that of 

 Mr. J. G. Anthony. It was obtained from Cuyahoga Falls, 

 Ohio, and contains eighty-four specimens. It is the more valu- 

 able from the reason that the geological horizon of the bed of 

 coal where the collection was made is fully ascertained, being 

 the lowest bed of the coal measures above the conglomerate. 



7th. Lately another collection of fossil plants of the Coal, 

 presenting the same advantage as the former has been made in 

 Pennsylvania for the Museum, from three different beds of 

 anthracite, whose horizontal position is equally well marked. 

 It contains one hundred and forty-six specimens, all carefully 

 determined and labelled. The species are recorded in the 

 catalogue, in a table, according to their geological horizon. 

 In comparing their distribution in that way, it is seen that two 

 species only belong to two different stations and none to the 

 three. Such tables established with care would help to solve 

 the problem of distribution of species at the different levels or 

 horizons, where our coal beds are formed, and furnish at the 

 same time reliable leading species for the identification of the 

 coal strata. 



8th. From the Coal measures of Nova Scotia, the Museum 

 has a series of about one hundred broken, small, poor speci- 

 mens, coming especially from the Joggins. This collection is 

 not of great value. 



9th. The formations older than the Carboniferous, are scan- 

 tily represented in the Museum, by thirty-nine specimens of the 

 Devonian of New Brunswick and Maine. Though these speci- 

 mens are named by Professor Dawson, they are so badly broken, 

 small and obscure, that little advantage can be derived from 

 them for comparison and identification of species.
