PROGRESS OF INVERTEBRATE PAL/AZONTOLOGY 
IN THE UNITED STATES FOR THE YEAR age 
BY CHARLES A. WHITE, M.D. 
FAIR amount of work has been done during the past year. 
No deaths have occurred among American paleontologists, 
and one new name appears among those mentioned in the present 
reviews. 
In the American Yournal of Science for January, pp. 40-46, Mr. 
Alexander Agassiz discusses the resemblance of living deep-sea 
Echinids with those of Cretaceous age, under the title, “ The con- 
nection between the Cretaceous and recent Echinid fauna.” 
In the June number of the American Journal of Science, pp. 
476-478, and one plate, Mr. John M. Clarke proposes and illus- 
trates three species and two new genera of Crustaceans, Spathio- 
caris and Lisgocaris, under the title “ New Phyllopod Crustaceans 
from the Devonian of Western New York.” In the July number, 
. pp. 55 and 56, he describes a Cirriped Crustacean from the De- 
vonian, under the the name of Plumutites devonicus. 
Dr. J. W. Dawson, in Proceedings of the Boston Society of 
Natural History, Volume XX1, p. 157, has a “ Note on Spirorbis from 
an iron-stone nodule from Mazon creek, Illinois.” Dr. Dawson 
notes the occurrence of a Spirorbis in connection with a fossil 
Millipede of the coal measures. He regards it as identical with 
a form found in the coal measures of both Nova Scotia and Ev- 
rope. This was published in 1881, but it was not noticed in my 
last year’s review. i 
Professor James Hall has prosecuted his great work for w 4 
State of New Jersey during the past year as he has been aonga 
the past. He also prepared a revised edition of all the pul 
tions he had previously made on the celebrated Niagara fossils 
Waldron, Indiana, with important additions of text and a 
now thirty-six in all, and published the work in Professor U a 
Annual report (the eleventh) of the Geological Survey of In Prov 
for 1881. He has now in hand another important work for 
fessor Collett’s next report. pee 
Professor Angelo Heilprin has made the following pe 
in the Proceedings of the Academy of Natural Scenes mise 
delphia for 1882: “On the discovery of Ammonites 1 ih 
of Tertiary age,” pp. 94; “ On the relative ages and class!
