1-4 A series of carapaces showing notable variation in the position and 
size of the eyes, partly due to different direction of compression [see 
text fig. 37]. Paratypes. x 2 
5 A carapace and three tergites. The carapace shows fairly normal out- 
line and position of eyes. The ocular nodes are preserved while the 
surrounding visual areas are broken out. This condition produces 
in fully compressed specimens the apparently very small size of the 
eyes, seen in figure 1. x 3 
6 Specimen showing the form of the six tergites. x 3 
7 A young entire specimen, still retaining a trace of the broader carapace 
and preabdomen. x 3 
8 An older individual, with mature characters. Natural size 
9g, 10 Two abnormally compressed carapaces. Figure 9, x 3; figure 10, x 3% 
II, 12, 13 Sternites showing the median suture, the transverse line and the 
antelateral lobes. Figures 11, 12 natural size; figure 13, x 3 
All specimens are from the Shawangunk grit at Otisville, Orange co., 
N. Y., and are in the State Museum
