Taeniaster. At their proximal terminations these oral ossicles 
are blunt and strongly elevated. 
Only the more conspicuous elements of structure can be de- 
tected in the specimens at hand. Therefore there is opportunity 
for glaring misinterpretations of structure on the part of the 
present writer. 
Locality. About 220 feet above Lake Huron, on Workman’s 
creek, three miles southeast of Meaford, Canada, in the Richmond 
group. 
Compared with Taeniaster cleg arts, Miller, from the Waynes- 
ville member of the Richmond, in Ohio, the adumbulacral plates 
are longer, distinctly overlapping, and bear correspondingly 
shorter spines; the oral ossicles are more blunt and more con- 
spicuously elevated at their proximal terminations; nevertheless 
it is with this species that the Meaford form is most closely related. 
Taeniaster miamiensis, Miller, from the Waynesville member 
in Ohio, is figured as having more strongly overlapping adumbu- 
lacral plates, with shorter spines, two being figured to a plate; 
the L-shaped form of the ambulacral plates is not indicated al- 
though it probably was present; the oral ossicles are figured as 
longer and with less divergent posterior terminations. 
It is evident that both Taeniaster elegans and Taeniaster mia- 
miensis must be republished before these species can be made 
available for purposes of correlating other forms believed to 
belong to approximately the same stratigraphical horizons. 
The types of both forms are now in the possession of the U. S. 
National Museum, but were in the exhibition cases at the time of 
my visit, from which it was difficult to remove them within a 
short time owing to the heavy plate glass front. Under these 
circumstances the examination of the specimens proved not suffi- 
ciently illuminating. While the Meaford specimens are regarded 
as indicating the Waynesville age of the strata in question, the 
actual identity of these specimens with Taeniaster elegans or 
Taeniaster miamiensis could not be demonstrated.
