Trilobites in the Text Book of Paleontology (Zittel’s).

the Upper Devonian of the United States.

The author remarks that this specimen was collected in 1870, and loaned to Prof. 
Hall and described as Eurypterus Beecheri Hall, in 1884, in 36th Ann. Rep. N. Y. Mus. - 
Nat. Hist. as Stylonurus excelsior as Hall’s species. This paper appeared some months 
later than Claypole’s paper, and the name Dolichocephala Lacoana has priority over 
Stylonurus excelsior and must be recognized. 
Claypole’s paper appeared in Proc. Am. Phil. Soc., vol. 21, April, 1883, to Jan., 1884. 
Discovery of Eurypterid remains in the Cambrian of Missouri.

Strabops Thacheri n. gen. et sp. 
See also Geol. Mag., Decade 4, vol. 8, 1901, pp. 559-564, figure. 
The generic name is in allusion to the inward turning or squinting of the eyes (squint- 
ing face). 
The cephalthorax is comparatively shorter and wider than in Eurypterus; the eyes 
are further forward, nearer together and more oblique, and besides it has a telson, but 11 
abdominal somites can be determined on the dorsal side, instead of 12 as in Eurypterus.
