Orthothetes becraftensis and Chonetes hudsonicus are species of the 
Oriskany limestone and are widespread at this horizon. 
(3) Ponta Grossa. 
A soft gray argillo-micaceous rock with : 
Orbiculoidea, large and small species; 
Homatonotus ; 
Bactrites ? 
Leptocoelia flabellites ; 
Lingula, large unidentified species. 
The collection submitted has but a single specimen from this 
locality, an Orbiculoidea, but I have completed my list from mate- 
rial which is in part, that to which Dr. Derby has referred in Neues 
Jahrbuch fur Mineralogie, 1888, v. 2, p. 173. 
He cites also, Spirifer, Rhynchonella, Vitulina and Streptorhyn- 
chus. A blacker shale from the same locality contains fragments of an 
Ophiuran. 
This rock promises a considerable and well preserved fauna and 
from our present knowledge of the species, it must be construed 
as of lower Devonic age. 
NoTE. To the specimens listed above as from near Jaguariahyva, 
I may add thereto from the latter locality the species described by 
me as Dalmanites gonzaganus. 
Among the specimens sent Dr. Clarke for identification was a 
small lot trom the Devonian of Para in North Brazil, collected by 
Dr. Francisco de Paula Oliveira, of the Coal Commission, the specimens 
of which have proven of great scientific interest as shown by the 
following remarks of Dr. Clarke: 
State of Para 
(4) Black shale, Ereré, State of Para. 
This rock contains abundantly : 
Nuculites, a small species ; 
Schizobolus truncatus, Hall. 
The latter is of more than ordinary interest.
