The representatives, rare in the collections, of this well-known species 

 are fully up to the average in size, very clear, and slightly mucronate. A 

 portion of a fruiting cone from the same locality has, so far as can be 

 observed from its external characters, the same size, divisions, bracts, and 

 arrangement of parts as the Stachannularia calathifera of Weiss, shown by 

 SterzeP to be the fruit oi Anntdaria sphenophylloides.

A comparison of the single example of this species found in the Mis- 

 souri material with the type specimen from "Coal C" at the Ontario Col- 

 liery, near Pittston, Pennsylvania,- leaves little doubt as to the specific 

 identity of these peculiar cones. The Missouri specimen, which comprises 

 about 15 cm. from the upper part of a strobilus, the base being lost, is 9 

 to 10 mm. in width, internodes being 2.5 to 3 nnn. long. Both this and 

 the type seem to be provided with short, delicate, narrow bracts, closely 

 impressed upon the verticils of sporangia or sporangium groups. Thouo-h
