brought my Annularia australis into close relation with his genus Cyclopitys. 
I am, however, not quite certain about this correlation, especially as I cannot 
remember having observed in the Australian specimens a transverse striation 
to both sides of the midrib of the leaflets, which Prof. Sclimalhausen points 
out as characteristic of his genus. I had for the original description only 
two specimens at my disposal (these are figured), and it would thus be of 
great interest, to pay attention to this species, whether additional specimens, 
when found, will show this characteristic striation or not. Up to this time 
I do not feel justified in separating our Australian fossil from the genus 
Annularia, although I shall mention it again amongst the Coni ferae. 
Locality and Horizon. — In the coal shales of the Lower Coal Measures 
(below Upper Marine beds) at Greta, New South "Wales (Carboniferous). 
4.— CALAMITE2E. 
Genus — CALAMXTES, Suckoiv , 1784. 
Obs . — Catamites comprises certain remains of equisetaceous plants, of 
•which generally the stems are represented, and which occur frequently in 
Carboniferous rocks, but are also known from other strata. The stems arc 
jointed, with diaphragms in the joints ; outside surface smooth or suleate ; 
inside surface always suleate ; leaflets in wdiorls, long, linear, free, deciduous. 
[Fructification a cone, with sterile and fertile whorls alternating, which is the 
chief difference from Lquisetum . There are certain leaved forms, known as 
Aster ophyllites, which by some authors are considered as the leaved branches 
of Catamites, and as such are called Calaniocladus. Prom Australia two 
species of Catamites are known, one of wiiieli has been originally identified 
by myself, while the other one was quoted on the authority of the late Prof. 
De Koninck.
