1912] BERRY—NEOCALAMITES 175 
HALLE (3) has recently suggested setting aside certain species 
formerly referred to the illy understood equisetaceous genus 
Schizoneura, to constitute a separate and perhaps collaterally 
related genus, for which he has proposed the name Neocalamites, 
and which he compares with the paleozoic Calamites. WILts (11) 
has supplemented this suggestion by comparing the species which 
are left in the genus Schizoneura with GRAND’-EuRY’s Calamoden- 
dron type of paleozoic Calamites, and LiGNIER (5) has recently 
described Calamitomyelon Morierei from the French Lias. 
The previously known species of Neocalamites are three in num- 
ber: N. meriani (Brongn.), N. hoerensis (Schimper), and N. car- 
rerei (Zeiller), and all are Keuper or Rhaetic in age. Both this 
genus and Schizoneura have been discussed by WILLs (10, 11) 
since the appearance of HALLE’s paper, so that further comments 
are unnecessary. 
In an examination of the recently reopened Carbon Hill mine 
in the Richmond coal-field of Virginia, two equisetaceous types 
were discovered which are apparently referable to Neocalamites. 
The one, represented by very abundant but exceedingly poor 
remains, is identified with Schizoneura virginiensis described from 
this area in 1883 by FonTAINE (2). This represents a species which 
appears to be very close to Schizoneura meriani Brongn., and con- 
sequently referable to Neocalamites as defined by Hattie. It is 
described by FontatneE as having several very fine veins, but this 
character is very obscure in all of the material and may or may not 
be true. It is something more than a coincidence that a like state 
of affairs seems to prevail in S. meriani described ordinarily as 
uninerved, but which Wixts has found to sometimes show several 
fine median veins. The other is an entirely new and remarkable 
type, which, in its superficial features at least, is very suggestive 
of the paleozoic Calamites with the Annularia type of foliage. 
The two were not found associated, although according to the mine 
engineer they both came from the same level, that is, the roofing 
shales of the 6-foot seam. The specimens were collected from the 
dumps, and their contemporaneous growth should therefore be 
accepted with caution, since the facies of the plants associated 
with each is slightly different, but probably equally explicable
