records is thus harmonized, as it appears. The same number of 
species is reported from the ‘Upper Devonian of the Ereré district, 
and the Carboniferous beds have yielded a similar number to Mr, 
H. H. Smith, among which there are probably some entirely new 
pears to extend 
South America, as elsewhere. ‘The fossils identified by 
Derby, which were collected on the Morgan expeditions, fe

Carboniferous fauna and to other s of similar age (Goal 
measures) in both North and South pai and in Kurope.+ The 
Cretaceous beds of the serras have afforded m many fossils, in places, 
but no details are furnished by the members of the Imperial 
Survey. 
Professor Hartt, at latest account, was engaged in a personal 
exploration of the Coal-Measure area in the southern province of 
Santa Catharina, where characteristic plant-fossils and workable 
beds of coal are known to exist.t The occurrence of coal in the 
valley of the Amazonas has 8s suspected ; there is probably no 
region in the world where it cou e more advantageously em- 
ployed. but as yet no. exposure of valuable beds has been reported. 
1, New Miverats. Mottramite, Roscoclite.—Prof. 
ia has recently described a new vanadium mineral, under the 
name 0 ottramite. It occurs as a crystalline incrustation on 
the Keuper sandstone at Alderley Edge, and at Mottram St. An- 
drew’s, Cheshire, England. The incrustation is usually thin, but 
sometimes 3 or r4 mm. in thickness. Occasionally in minute crys- 
tals of a black velvety appearance in the mass, but by transmit- 
ted light yellow. Also compact, opaque, and of a purplish brown 
color. Luster resinous. Strea yellow. H.=3; G.=5'894. The
