Geology and Paleontology. 57 
we learn the Survey began work June 24th, with a corps of a 
director, three paid and seven volunteer assistants. The work done 
the first year has been the triangulation of the immediate vicinity 
of Little Rock ; the examination of localities reported to yield gold 
and silver, especially in Garland and Montgomery counties; a 
reconnoissance in the central part of the State; tracing the limits 
of the Cretaceous in the southwestern part of the State. The bill 
providing for the survey makes appropriations for its continuance 
for two years. 
GrEoLocicaL News.—Patmozoic.—Dr. J. V. Deichmiiller 
describes two new species of the genus Etoblattina Scudder obtained 
at Griigelborg, near St. Wendel (Rhenish Prussia), not far from 
a spot where fish, insect and plant remains have been previously 
ee They are described under the titles of E. ornatissima and 
. rollei. 
CRETACEOUS.—Mr. A. S. Woodward concludes, after examination 
of the five series of examples in the British Museum, that Cyclobatis 
oligodactylus, the so-called “ Torpedo,’ from the Cretaceous of 
Mount Lebanon (Syria), is really a member of the sting-ray family 
(Trygonidz). Among his reasons are: The pectoral fins are unin- 
terruptedly continued to the end of the snout, and were thus, prob- 
ably, confluent in front—a condition never met with among the 
Torpedinide ; the pelvic arch is placed far forward; there are no 
traces of median fins, and the skin is armed with spinous tubercles. 
From an examination of specimens in the Cambridge and 
Brighton Museums (Eng.), Mr. A. S. Woodward concludes that 
the puzzling genus Ptychodus, which was by Agassiz and Owen 
referred to the Cestraciontid, is doubtless a true ray, though 
possibly belonging to an extinct family. 
Mr. J. W. Davis (Trans. Roy. Dublin Soc., 1887) describes the 
fossil fishes of the chalk of Mount Lebanon. In this important 
eels yet known,—are among the Teleosteans.
