These organisms, as described and figured by Newberry (loc. cit.), are always 

 3-lobed or winged, with the middle one larger than the other two, as is the case in 

 our figs. 8, 9, in regard to the identitj^ of which there can be no question. The frag- 

 ment represented by our fig. 10, however, is manifestly too imperfect for positive 

 identification, and in figs. 11, 12 the tripartite divisions are not well defined and 

 the indications are that in any event these were all about equal in size. For this 

 reason the identity of the latter tlrree figures is perhaps questionable, and it is possible 

 that they may represent small specimens of T. major Hollick, the species last 

 described.

Calycites obovatus n. sp. ^ 



PI. V, fig. 23. 



Organism consisting of a petioled nucleus, to which are attached two entire, obovate, longitudinally 

 striated, wing-like appendages, each about 1.5 centimeters long by 1.3 centimeters in maximum width. 



This specimen is intermediate in size and shape between the species last described 

 and certain forms of Tricalycites major Hollick," with which species it may eventually 

 have to be included. It is, however, unquestionably 2-winged, and the wings are 

 shorter and relatively broader than in any recognized specimens of the latter.

Calycites alatus Hollick. 



PI. V, fig. 24. 



Calycites alatus HolHck, Bull. New York Bot. Gard., vol. 3, 1904, p. 417, pi. 72, fig. 8. 

 Tricalycites papyraceiis Newb., Hollick, Trans. New York Acad. Sci., vol. 15, 1895, p. 6. 



This species may perhaps be regarded as a small form of the one last described 

 and possibly as one extreme of a series of forms of which the other extreme is repre- 

 sented by Tricalycites major.
