and other characters of palm leaves, as has since been shown by- 

 Mr. Teschemacher. 



Three specimens of this plant were also found in a specimen 

 of the shale, which I obtained on my first visit to the mine. I 

 found a perfect Lepidostj'obus, a fruit of the Lepidodeudron, 

 according to Brongniart. A number of stems of plants were 

 also found, and some of them, from their forms and delicate 

 curves, appeared to have been succulent hollow stems, or aquatic 

 plants of some kind. These have proved to be species o^ Sphcs- 

 rcedra. {Lindley Sf Hiitton, Vol. iii. PI. 159.) 



Nos. 1 and 2 are specimens of the Lepidodendron found in 

 shale of the Albert coal mine. No. 1 is the stem of the plant, 

 with its carbonized bark, having all the cortical scales which are 

 so characteristic of the genus. On comparing this plant with 

 the Lepidodendron gracile, in BrongniarVs Histoire des Vege- 

 taux Fossiles, Vol. ii. Plate 15, I feel no doubt of its close ana- 

 logy with that species, which is a well known plant of the coal 

 formation. 



Nos. 3 and 3 bis. are specimens of the Lepidostrohus found 

 by me in the shale of the Albert coal mine. No. 3 is the fruit 

 in relief, and 3 bis. is the counter-print in the rock split from it. 

 It is difficult to identify the species by comparison with Brongni- 

 art's drawings; but no one who compares it with the species of 

 Lepidostrohus, in his plates, (Tome ii. Plates 22, 23, and 24,) 

 will have any doubt of its belonging to that genus. It is probably 

 the fruit of the Lepidodendron gracile, above-mentioned. 



Nos. 4 and 5 are specimens of SphoercEdra of the Albert mine. 



No. 6 is our palm-like leaf. It is too wide to be the leaf of a 

 Lepidodendron. Further researches may decide this question. 

 I have Lepidodendra^ with their beautiful foliage, from the shales 

 of the coal mines on the Grand Lake, upon the St. John River, 

 very closely resembling the plant figured in Brongniart'^ s Vege- 

 taux Fossiles, (Tome II. PI. 17, Fig. 1. ;) but none of the leaves 

 have a width of more than half an inch, while these are more 

 than two inches wide. 



Mr. Ayres presented a new description of Chirodota 

 arenata Gould. 



This species is one of the most abundant in our vicinity. It
