Remarks. Considerable confusion has arisen in regard to this plant. 

 Sternberg gives a figure of a Sigillaria on pi. xv., which he names Rhytidolepis 

 ocellata. To this he mentions as a synonym Palmacites (Sigillaria} variolatus, 

 Schlotheim (Petrefactenkunde, p. 395, pi. xv. fig. 3). There can, I think, remain 

 no doubt as to Schlotheim's plant being a decorticated specimen of Sigillaria 

 tessellata. This has already been pointed out by Brongniart (Hist, d.' Veget. 

 Foss. p. 439). Hence the reference to Schlotheim must be excluded from 

 Sigillaria ocellata, Sternberg. 



Sternberg further gives as a synonym to his Sigillaria (Rhytidolepis) 

 ocellata, Palmacites (Sigillaria) oculatus, Schlotheim (Petrefactenkunde, 

 p. 394, pi. xvii.). This is also quite distinct from the plant figured by Stern- 

 berg on his plate xv., the leaf-scars having a distinct notch on their upper 

 margins, the lateral angles being much less pronounced. Palmacites oculatus, 

 Schlotheim, has been excluded from Sigillaria ocellata by Brongniart (Pro- 

 drome, p. 64). Brongniart, though keeping separate Sigillaria oculata, 

 Schlotheim, from Sternberg's Sigillaria ocellata, unites Sternberg's plant, in 

 doubt, with his Sigillaria pachyaerma. This seems to be an error. 



The main figure in Sternberg's plate is decorticated, but shows the furrows 

 to be alternately constricted and enlarged, a character scarcely observable in 

 Sigillaria pachyderma. Of the other figures given by Sternberg of his 

 Sigillaria ocellata, that on the right hand of his plate is difficult to explain, 

 but that at the lower left hand corner, which is an impression of a portion of
