tho outer cont or floshy testa, and exhibits the true character of the 

 terminal notch or foramen.* 



Genus Triqongcarpum — Bronq. 



118. Trioonocarpum racbmosum, Dawson— (Pl.XIX, Fig. 227.)— J. 0. 

 8 , XVIII, 324 ; PI. XVI, Fig. 47.— M. D., St. John, New Bruns- 

 wick. 



" Ovate, obtusely acuminate, in some specimens triangular at apex. In 

 flattened specimens tho envelope appears as a wing. Fruits 

 attached in an alternate manner to a thick, flexuous, furrowed 

 rachis." 



114. Trigonooarpom perantiquum, S. N.— (PI. XIX, Fig. 228.) 



Ovate; when full grown, half an inch wide and one inch long, with 

 obscure indicationa of riba toward the narrow end. 



St. John, Now Brunswick, in Prof. Hartt's collections. All are badly 

 preserved. They resemble some of the Carboniferous Trigonocarpa. 



All Trigonocarpa, properly so called, are, I have no doubt from their 

 associations, fruits of SigillaritB or of Conifers ; and the first species men* 

 tioned above shows that in some cases at least they were borne in racemes . 

 a circumstance which should perhaps connect them with some of the spikes 

 of fructification of the genus AnViolithea. 



Genus Carpolithes. — Sterne. 



115. Carpolithes siliqua, Dawson.— J. G. S., XIX, 465 ; PI. XVII, 

 Fig. 4. — U. D., Perry, Maine. 



" Elongate, smooth, flattened, sides slightly sinuate ; two inches or less 

 in length ; a quarter of an inch or less in breadth." 



118. Carpolithes spicatus, Dawson. — J. G. S., XIX, 461 ; PI. XVII, 

 Fig. 15. — U. D., Perry, Maine. 



" Carpels or spore-cases : oval, about a line in length, apparently with 

 a thick outer coat ; densely placed on a thick rachis." 



This I now think may be the fruit of a species of Arthrostigma. 



• Though I hare no doubt that the abore is the correct interpretation of C. cornutum, I 

 do not regard it aa applicable to all Cardiocarpa, in some of which the outer envelope, 

 initead of being succulent, raay have been compressed into a wing. This was probably th* 

 caw with C. Baileyi, which as M" Carruthers aud Dr. Hooker have pointed out to me, is not 

 diMimilar from the winged seeds o. 'he curious WtlwiUchia mirabUit,
