Sîgillaria ocidi felis Abbadü, Coiitributo alla Flora Carbouifera tk'lla Ciua, 

 p. 141, pi. V, figs. 1, 2. 



Sigillaria FogoUiana Abbado, Le. p. loG, pi. 111, figs. 1-3. 

 Sigîllaria polymorpha Abbado, Le. p. 1-39, pi. IV, figs. 1-4. 



The specimen shown in fig. 5, in spite of its being a small 

 fragment is, I believe, a part of a stem belonging to the above 

 species already described by Zalessky as from the same place. 

 The form as well as the size of the leaf-cushions most resembles 

 fig. 7 of the same author. The cicatrices are not well preserved, 

 still so far as can be seen from our specimen, they are also similar 

 to those of Abbado's species. 



Fig. 1 represents a cast of the decorticated specimen of a 

 Lepidodendron also found at Yen-tai. The cushions are represented 

 by rhombic depressions, a little broader than high, and with a 

 median longitudinal groove corresponding to the shorter diagonal 

 of the rhomb. The specimen looks like fig. 9 of Zalessky, 

 although the rhombs are smaller and more crowded. Still, I 

 presume, it belongs to the same species. 



8. SIGILLARIA br. 



ri. II. Fig. 4. 



A fi'agment of a Sigillmia whose sjjccific dctcimination is 

 not possible. It is an impression of a stem consisting of flat, 

 indistinct, parallel ribs which are generally about 2 mm broad, 

 and furnished with fiiie, straight, longitudinal striations. On 

 these ribs, there are small distant pits and tubercles whose 

 distribution is not quite regular. It is probably the Sigillaria, in 

 a subepidermal state of preservation commoidy known under the 

 name of Syrinyodendron.
