FRUITS. 



Rhabdocarpus, Groepp. et Berg. 



MTidbdocarpus ohlongatus, Sp. nov,, PI. XXXYII, Figs. 

 8 and 9. 



In figs. 8 and 9, PI. XXXVII, are depicted fragments of a 

 fruit which seems to belong to Hhahdocarpus of Goep. and 

 Berg. It is elliptical or oblong in form, and shows 6 or 7 

 longitudinal ridges. Fig. 8 shows a nut with the pericarp 

 detached, in which the body of the nut seems quite smooth, 

 and marked only by longitudinal lines. 



Habitat. — Roof-shales of the Waynesburg Coal, Cass- 

 ville, W. Ya. 



Carpolithes, Sternb. 



At only one locality in the Upper Carboniferous strata 

 have we ever seen any nutlets. This is at Cassville, W. 

 Ya., where we have found so many and varied plants. The 

 most of the nutlets here come associated with the remains 

 of Caulopteris. 



Carpolithes M-carpa. Sp. nov., PL XXXYII, Figs. 6 and 7. 



(Fruits borne in pairs on a common pedicel, rather rough, 

 oval in shape, with the larger extremity free and tapering 

 to the point of attachment.) 



This fruit is evidently somewhat closely allied to C. fas- 

 ciculatus, Lesqx., Yol. II 111. Rep., PI. 46, Fig. 7. We 

 have seen four specimens of the fruit, and in all cases they 

 showed the form here figured, i. e., in pairs. 



Habitat. — Roof -shales of the Waynesburg Coal, Cassr 

 ville, W. Ya. 



Carpolithes marginatus. Sp. nov., PL XXXYII, Fig. 1. 



(Fruit with a very regular elliptical outline, and margined 

 all around by a raised rim or border. The surface is rather 

 smooth and shows no point of attachment. This fruit was
