In this paper two widely sep- 
arated Ordovician faunas are 
described, one coming from the 
Province of Shan-tung, the other 
from eastern Ssi-ch’uan. The 
first of these faunas consists of 
poor material, the exact age of 
which it is impossible to de- 
termine. It is, however, re- 
ferred to the Middle Ordo- 
vician, or Mohawkian. The sec- 
ond fauna is correlated without 
much question with the Black 
river of America on the one 
hand, and the Vaginatus horizon 
of Russia on the other. A de- 
tailed description of fossils is 
given, with figures, and com- 
parisons are made with other 
known Ordovician faunas of 
eastern Asia. The material de- 
seribed is the property of the 
U. S. National Museum.

WHITE, Davip—Continued. 
Resinous substances, in mi- 
croscopical particles and as 
lumps visible to the naked eye, 
appear to be present in all, or 
nearly all, coals of Mesozoic or 
Tertiary age that have not been 
subjected to such dynamic al- 
teration as to cause the trans- 
formation of the resins. This 
transformation occurs when the 
fixed carbon in the coals ap- 
proaches 70 per cent pure coal 
basis. The author describes 
and illustrates resins and resi- 
nous substances in Paleozoic 
coals of a rather low bitumi- 
nous rank, thus confirming the 
interpretations suggested by 
various paleobotanists that some 
of the secretory cells or canals 
noted in petrified fragments of 
certain Paleozoic plant types 
may have contained resins.

cies of Silurian fossils from the 
Edmunds and Pembroke formations 
of Washington County, Maine.

This paper contains descrip- 
tions of the more characteristic 
fossils of the Silurian forma- 
tions mapped in the WBastport 
folio of the U. S. Geological 
Survey. Hight species are de- 
seribed from the Edmunds 
formation, and 12 from the 
Pembroke. All of these are 
illustrated and the types are in 
the collections of the U. S&S. 
National Museum. 
Recurrent Tropidoleptus zones 
of the Upper Devonian in New York, 
Prof. Paper, U. S. Geol. 
Surv., 79, 19138, pp. 
1-103, pls. 1-6, figs. 
1-18. 
As the result of a study of 
the Upper Devonian faunas of 
the Watkins Glen and Catatonk 
quadrangles, New York, Profes- 
sor Williams made an interest- 
ing discovery of the recurrence 
in beds of Portage and Chemung 
age of fossils characteristic of 
the Middle Devonian. This led 
to an intensive study of the 
faunas, the results of which 
are given in the present paper.
