Remarks. — Not common. 



I have observed two specimens of this species from Camerton, — one in the 

 Bristol Museum, the other kindly given me by Mr G. West, — which show the 

 peculiarity of a double row of tubercles, one row at each extremity of the ribs ; 

 thus each nodal line has a row of large tubercles immediately below it, and a 

 row of smaller tubercles immediately above it. The same peculiarity is figured 

 by Brongniart (C. decoratus, Brongniart (not Artis), Hist. d. veget. foss., pi. 

 xiv. figs. 3, 4) and Weiss (C. ramosus, Steinkohlen-Calamarien, part ii. p. 108, 

 pi. ix. fig. 2). It is shown from the specimen given me by Mr West, which is a 

 portion of the stem near its base, that the larger tubercles occupy the normal 

 position, viz., the upper extremities of the ribs, and the smaller tubercles the 

 lower extremity. Weiss's figure is therefore, as suspected by him, drawn in 

 inverted position. My Camerton specimen also shows the further peculiarity, 

 likewise mentioned by Weiss in the description of his example, that many of 

 the ribs, instead of alternating at the nodes in a normal manner, are exactly 

 opposite. This latter abnormality, however, in the case of a few ribs, is not a 

 very uncommon phenomenon on stems of Calamites. 



Localities : — Radstock ; Camerton.
