S. apima Hall, S. plano-convexa Shumard, Ritziu punctulifera 
Shumard, and a number of other species characteristic of the — 
North American coal measures. 
Mr. Chandless collected carboniferous fossils from the Paranary 
and Amana, branches of the Maué-assir, a tributary of the Ama — 
zonas between the Tapajos and Madeira. The localities are about — 
one hundred miles west of Itaituba, arid the beds and fossils are 
the same as at that place, as is proved by specimens kindly pre 
sented by Mr. Chandless. - . 
A specimen of rock given me by Sr. Gabriel Vierra Lobes of a 
Abydos, and said to have been found on the river Trombetas, con- 
tains some of the same species and is interesting since it indicates 
the occurrence of the same formation on the north side of the a 
Amazonas, where Devonian rocks also occur. dem 
It is interesting to notice in this connection that the Brachiopods 
described by d’ Orbigny, Salter and Zoula from Lake Titicaca, 
Santa Cruz, and Cochabamba in Bolivia are in great part identical 
with the Brazilian and North American coal measure forms, 
` are in all cases more nearly allied to them than to any others. — 
In a small collection of Peruvian fossils forwarded by Profs 
Orton for examination, I have recognized Ritzia punctulifera 
Shumard, and Spirifera camerata Morton (S. Condor @ Orb.), i0 i 
a pebble from the bed of the Pichis River, a branch of the Pachitea, — 
one of the western tributaries of the Ucayali. This is 4 ame : 
locality for the carboniferous situated about six degrees north of 
Lake Titicaca. : 5 
Carboniferous beds in the south of Brazil in the prore 
Santa Catharina and Rio Grande do Sul, are described in +1" 
Hartt’s Geology and Physical Geography of Brazil. Toe aa 
also of coal measure age, containing workable beds of coal wi 
characteristic coal plants. —O. A. DERBY. ‘
