484 ` Recent Literature. [May, 
recently opened and coal beds worked in Virginia, Tennessee, 
Alabama, Georgia, etc., at a lower stage than that of the Northern 
basins, a mass of specimens of fossil plants, not yet known in 
this country, have been discovered and sent from those localities.” 
Mr. Lesquereux adds he has had to leave a large amount of 
specimens still unexamined, and he foresees “that there is left 
unknown, for future research and study of the history of the 
vegetation of the coal, an amount of materials at least as great 
and as important as that which has already been published.” 
Mr. Lesquereux acknowledges in a note the aid he has received 
in the loan of specimens from Mr. R. D. Lacoe, of Pittston, Pa., 
“ who has directed for years explorations, still continued, in the 
more interesting localities of the coal-fields of North America. 
He has thus brought up, at great expense, a collection of fossil 
plants of divers formations, of insects, crustaceans, etc., which is 
not only by far the largest and most valuable of any in America, 
but which certainly may compare in this specialty with the rich- 
est collections of any of the European museums,” 
The other report is marked P.P.P., 1884, and contains two 
palzontological papers, valuable in themselves and for their illus- 
trations. The first one, by Mr. C. E. Beecher on the Ceratiocar- 
idæ of the Upper Devonian measures, we have already noticed 
in this journal; the second is a note by Professor James Hall on 
the Eurypteride from the lower coal measures, and it is illus- 
trated by six heliotypes, an excellent way of illustrating these 
fossils. One new species (Eurypterus potens) is described, and the 
remains of other species fully illustrated. 
THE ZOÖLOGICAL RECORD FoR 1883.\—That the work in sys- 
tematic zodlogy throughout the scientific world went on in 1883 
much as in former years, is proved by the fact that the size of 
each of these useful records remains about the same from year to 
year. The present volume, which contains no references to the 
Arachnida, is only twenty-eight pages shorter than its predeces- 
sor, in which that class occupied thirty-three pages. : 
he year 1883 was, so far as regards the mammals, chiefly 
marked by the large number of paleontological books and papers 
which appeared, among which those of Ameghino, Cope, Filhol, 
and Lydekker are the most prominent. 
While there are no striking novelties in ornithological work, 
the year is reported to have been remarkable for a large amount 
_of steady work. Little appears to have been done with the rep- 
_ tiles and Amphibia; beyond special papers no works on ichthology 
of general importance appeared this year. 
` As usual over half the volume is devoted to the Crustacea and 
especially the insects. Regarding the former several monographs
