G. crinitus, thecae x 7. 



G. crinitus 



As stated above, I am not sure that tlie reference to Goniograptus 

 is correct, l)ut I hesitate to form a new genus for its reception, till 

 a complete hydrosome is found. The form of the thecae is much 

 more primitive than that of the typical species of Goriiograpfiis. 



Horizon. — Upper Bendigonian and Lower Castlemainian, but 

 commoner in the loriner.
