478 THE CARBONIFEROUS SYSTEM. 



3. T. intermedium, spec. nov. (Fig. 173, D). Allied to T. olivm- 

 formis, but larger and more elongated. M. C, Joggins (J. W. D.). 



4. T. avellanum, spec. nov. (Fig. 173, F). Allied to T. ovatum, 

 L. and 11. ; three-ribbed, size and form of a filbert. M. C, Joggins 

 (J. W. D.) ; Sydney (R. Brown). 



5. T. minus, spec, nov. Half the size of T. Hookeri, and similar in 

 form. M. C, Joggins (J. W. D.). 



6. T. rotundum, spec. nov. Small, round-ovate, slightly pointed. 

 M. C, Joggins (J. W. D.). 



7. T. Nceggerathi, Brongn. (Fig. 173, E). Newer Coal formation, 

 Pictou (J. W. D.). 



Rhabdocarpus, Goepp. and Bergm. 



1. Rhabdocarims (?), spec. nov. Ovate acuminate, less than 



half an inch long. M. C, Joggins (J. W. D.). 



2. R. insignis, spec. nov. (Fig. 173, G). 1-5 inch long, ovate, smooth, 

 with about seven ribs on one side, and the intervening surface ob- 

 scurely striate. The nature of this fossil is perhaps doubtful ; but if 

 a fruit, it is the largest I have seen in the Coal formation. U. C, 

 Pictou (J. W. D.). 



Calamites, Suckow. 



1. Calamites Suckovii, Brongn. (Figs. 39 and 163, A). This 

 species is one of the most common in an erect position. It has 

 verticillate branchlets, with pinnate linear leaflets. M. C, Sydney (R. 

 Brown) ; Joggins (Lyell ; J. W. D.) ; Grand Lake and Springhill 

 (C. F. Hartt) ; U. C, Pictou (J. W. D.) ; Coal Creek (C. B. Matthew). 



2. a Cistii, Brongn. (Fig. 163, B). M. C, Joggins (J. W. D.) ; 

 Sydney (R. Brown) ; Grand Lake (C. F. Hartt) ; Bay de Chaleur 

 (Logan) ; Coal Creek (C. B. Matthew). Often found erect. Its leaves 

 are verticillate, simple linear, striate, apparently one-nerved, and three 

 inches long. 



3. C. cannceformis, Brongn. M. C, Joggins (Lyell ; J. W. D.) ; 

 Sydney (R. Brown). 



4. C. ramosus, Artis. Possibly a variety of C. Suckovii. M. C, 

 Joggins (J. W. D.) j Sydney (R. Brown). 



5. C. Voltzii, Brongn. (Fig. 37). (C. irregularis, L. and H.) M. 



C, Joggins (J. W. D). Often erect ; has large irregular adventitious 

 roots. This species is regarded by Brongniart as probably belonging 

 to Calamodendron. 



6. C. dubius, Artis. M. C, Sydney (R. Brown) ; Joggins (J. W. 



D. ; Logan) ; U. C, Pictou (J. W. D.).
