The authors describe the following Fossil Crustacae: 
Trilobita: Cryphaspis Stephanophara Hall. Homalonotus DeKayi Green. Phacops 
rana Gr., P. cristata Hall and var. pipa Hall. 
Dalmanites (Cryphaeus) Boothi Gr. 
The genus Cryphaspis was proposed by Dr. Green for certain Devonian Trilobites, 
in 1837, Am. Jour. Sci, vol. 32, 1837, p. 343, with figures of the genotype Cryphaeus 
Boothi and C, calliteles. 
The term was pre-occupied for the Coleoptera in 1833. 
Burmeister Org. ‘Tril, 1843, under his sub-group Phacops, in which the pygidium 
has long spines on its circumference, classes dsaphus archnoides Goldf., a similar 
species, under Phacops. ‘This species is now referred to Cryphaeus punctatus Steininger, 
1831. 
Milne Edwards Hist. Nat. Crust. vol. 3, 1840, pl. 34, fig. 8, copies Hoeninghaus’s 
figure of Calymmene archnoides, 1833, and refers it to his new genus Pleuracanthus, at 
this time pre-oceupied by Agassiz and Gray for fossil fish, 1832. 
Corda Mong., Bohm Tril, 1847, p. 242, pl. 6, fig. 67, uses the term Metacanthus for 
Phacops stellifer Burmiester, and that of Asteropyge, on p. 241, with Calpmmene. 
arachnoides Goldf. as the genotype. 
All the species described under Cryphaeus Green should take the generic name of 
Asteropyge Corda. 
In the European species of this genus the terminal spine upon the pygidium generally 
exceeds in length all of the five marginal spines on each side.
