The reviewer remarks (Schuchert): “It is truly a monumental work and a model 
for all paleontologists to follow.” 
In this work one can study Eurypterida from any view point permitted the palaon- 
tologist. Here we find their chronology, their development from baby stages, pro- 
phetic of unknown ancestors, to adults; and their relations to scorpions, horseshoe crabs, 
Trilobites and even to hypothetic annelids. 
The authors illustrate in text and plates the following species: 
Strabops thacheri Beecher. 
Eurypterus. 
The American species of Eurypterus readily fall into three subdivisions: 
(A) Those that groups themselves around E. remipes. 
(B) Those that vary in different directions from this group, but are approximately 
contemporary—E. Dekayi, etc. 
(C) The later Carbonic species. 
Under this genus the authors describe: 
Eurypterus remipes DeKay, BE. lacustris Harlan, E. lacustris Hall var. pachychirus 
Hall, &. DeKayi Hall, E. maria Clark. This species differs from American congeners, 
due to the terete form of the body that apparently is without preabdominal expansion. 
Eurypterus pygmaceus Salter differ but slightly. Eurypterus megalops nov., E. 
microphthalmus Hall. The authors refer F. eriensis Whitfield, to this species. Eury- 
pterus pittsfordensis Sarle, E. (Dolichopterus 2) prominens Wall, E. pustulosus Hall. 
Authors refer E. giganteus Pohlman and E. globicaudatus Pohlman to this species. 
Eurypterus pristinus nov. E. ranllarva noy., E. 2 (Dolichopterus 2?) stellatus nov., E.
