DESCEIPTIONS OF SPECIES. 85 



Dalbergia hyperborea Heer.? 

 PL XXXII, fig. 10. 



Dalbergia hyperborea Heer, Fl. Foss. Arct., vol. 6 (abth. 2), 1882, p. 102, pi. 26, fig. 4a; Hollick, Trans. New 

 York Acad. Sci., vol. 11, 1892, p. 103, pi. 4, fig. 7. 



The identity of this specimen is probably with either D. hyperborea Heer (loc. 

 cit.) or D. Rinkiana Heer, a the close resemblance between which was recognized by 

 Heer. He emphasizes, however, the rounded cordate base of the former as a distin- 

 guishing feature, and this is quite well defined in our specimen.

Dalbergia minor n. sp. 



PL XXXII, fig. 12. 



Leaf small, entire, about 1.3 centimeters long, slightly inequilateral and curved, about 6 millimeters wide 

 at the abruptly rounded base, tapering to the apex; nervation obscure. 



This is not a very satisfactory specimen upon which to base a description of a 

 new species, but I have been unable to identify it with any .heretofore recognized 

 Cretaceous form. In general appearance it is suggestive of the genus Dalbergia. 



Locality: Gay Head, Marthas Vineyard. Collected by David White. Speci- 

 men in U. S. Nat. Mus. 



Dalbergia irregularis n. sp. 

 PI. XXXII, fig. 11. 



Leaf about 3.8 centimeters long by 1.8 centimeters wide in the middle, entire, inequilateral, curved, taper- 

 ing to an acute apex, rounded at the base on the narrower side, cuneate on the broader side; nervation reticu- 

 late, leaving the convex side of the midrib at acute angles and the concave side at right angles. 



The fossil species which most nearly resembles our specimen is Leguminosites 

 dalbergioides Etts., b from the Tertiary of Europe.

Phaseolites elegans n. sp. 



PI. XXXII, fig. 4. 



Dalbergia Rinkiana Heer. Hollick, Trans. New York Acad. Sci., vol. 12, 1893, p. 236, pi. 6, fig. 4. 



Leaf inequilateral, entire, ovate-falcate in outline, tapering to a curved apex, narrowed to an acute wedge- 

 shaped base, short petioled; secondary nerves few or obscure, those on the broader side forming angles with 

 the midrib more acute than those on the narrower side, all curving upward. 



This leaf has some of the characteristics of Dalbergia Rinkiana Heer c and cer- 

 tain of the forms figured under Phaseolites formus Lesq. d It also bears a more or 

 less close resemblance to our fig. 5, pi. XXXII, which I have referred to Hymensea 

 dakotana Lesq. Its almost perfect ovate-falcate outline, however, serves to dis- 

 tinguish it from any of the published figures of these species.
