Measurements. — The type, which is twisted as shown in the 
photograph, gives the following approximate measurements: 
total length, about 115 mm.; width about 70 mm.; length, 
cephalon, 40 mm.; width, axial lobe of thorax, 25 mm.; length, 
pygidium, 37 mm.; width, 70 mm. 
Hitherto, two species of Hemigyraspis have been described 
from American deposits. One was described by Matthew 1 
from the basal Ordovician of Cape Breton, as Asaphellus ? 
planus , and a second by the writer from the lowest fossiliferous 
zone in the Beekmantown at Bellefonte, Penna. ( Hemigyraspis 
collieana ) 2 . From both these, and from all known European 
species of the genus, the present specimen differs in the spinose 
terminations of the segments of the thorax. 
Locality. — The specimens are from a locality 3 miles east of 
Golden, B.C.,|and were collected by Mr. R. G. McConnell in 
1886.

This specific name seems to have been very successful in 
evading the eyes of describers of trilobites, and it was not until 
recently that the writer’s curiosity to know what form it was 
which Vogdes referred to Ogygia (Catalogue of Trilobites, p. 324) 
caused him to unearth it.
