The author remarks that this specimen was collected in 1870, and loaned to Prof. 

 Hall and described as Eitrypterus Beecheri Hall, in 1884, in 36lh Ann. Rep. N. Y. Mus. 

 Nat. Hist, as Styloriunis excelsior as Hall's sipecies. This paper appeared some months 

 later than Claypole's paper, and the name Dolic hocephala Lacoaria has priority over 

 Stylonurus excelsior and must he recognized. 



Claypole's paper appeared in Proc. Am. Phil. Soc, vol. 21, April, 1883, to Jan., 1884.

The generic name is in allusion to the inward tin-ning 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.
