aya Progress of Invertebrate Paleontology in [ April, 
Insects, has also lately issued, and an abstract of it has appeared 
in the January (1880) number of the American Fournal of Science 
and Arts, pages 72-74. An interesting article from his pen has also 
lately appeared in the Report of ‘Progress of the Geological Sur- 
vey of Canada for 1877-1878, pages 175-185, on “ The Fossil 
Insects collected in 1877 by Mr. G. M. Dawson in the interior of 
British Columbia.” The insects described are all referred to the 
Tertiary period, and represent four orders; one species being re- 
ferred to the Hymenoptera, two to the Diptera, ten to the Cole- 
optera and four to the Hemiptera. Among the latter he proposes 
the new genus Planophlebia. 
The duties of Prof. A. Hyatt at the Museum of the Boston 
Society of Natural History, have made such demands upon his 
time for the past year, as to retard the progress of his special 
investigations. He is still working, however, upon the Ammonites, 
being now specially engaged upon the Arietidæe, and also upon . 
the Steinheim shells. His only published work for the past year 
_ is embraced in a paper, by the writer of this article, on “ Fossils 
of the Jura-trias of South-eastern Idaho,” in the Bulletin of the 
U. S. Geological Survey of the Territories, Vol. v. Prof. Hyatt 
there proposes and diagnoses the new Cephalopod genus Meeko- 
ceras. 
Mr. W. H. Dall published in the Proceedings of the U. S. 
National Museum, Vol. 1, page 3, an interesting note on the 
occurrence of a Post-pliocene deposit containing recent species of 
marine shells in a semi-fossilized condition, at the head of a 
cañon near San Luis Rey, California, twelve miles from the sea 
and six hundred feet above tide water. 
This determination of species is especially interesting and 
important, since it proves a considerable elevation of that coast 
to have taken place at a comparatively recent date. He also pub- 
lished in the same volume, pages 10-16, an article on “ Fossil 
Molluscs of the Later Tertiary of California,” describing six new 
species, and, giving a table showing the known distribution OE 
forms and the proportion of fossil and recent species respec- 
tively. 
Mr. Angelo Heilprin has published in the Proceedings of the 
Academy of Natural Sciences at Philadelphia for 1879, t three 
articles bearing respectively the following titles: “On some new 
Eocene Fossils from the Claiborne marine formation of Alabama;”
