Among the described fossil forms Sophora salvadorana greatly 

 resembles Sophora europaea, 22 which was compared by Unger, its 

 original describer, with the existing Sophora tomentosa. Sophora 

 europaea has been identified by numerous students at a large number 

 of European localities, extending from the Oligocene through the 

 Miocene. 



The present species is based upon two specimens from the yellowish 

 sandy micaceous clay found along the trail, 2\ miles northwest of 

 La Salvadora. 



Holotype.—C&t. No. 36436, U.S.N.M. 



POSITION UNCERTAIN. 

 Genus LEGUMINOSITES Bowerbank. 



LEGUMINOSITES VENEZUELENSIS, new species. 



Plate 107, fig. 2. 



Leaflets small, apparently sessile, very inequilateral, with an acute 

 apex and a very inequilateral base. Margins entire. Texture 

 subcoriaceous. Length about 1 cm. Maximum width about 5 mm. 

 Midrib thin, somewhat curved. Secondaries immersed, a few 

 camptodrome pairs, more ascending in the narrower side of the 

 lamina, the basal one in the wider side of the lamina more prominent 

 than the others. 



This small leaflet has a characteristic form; the acute tip is not 

 obviously inequilateral, but the lamina on one side is twice as wide 

 as on the other; the base on the narrow side curves to form an acute 

 angle with the midrib ; that on the broad side continues downward to 

 form a prominent auricle. 



This species is based upon a single specimen and its counterpart 

 from the sandy clays near La Salvadora. Consequently it seems 

 desirable to refer it to the form-genus Leguminosites rather than to 

 attempt comparisons with recent species of Leguminosae, which are 

 so numerous in this region at present, and so extremely difficult to 

 differentiate by means of the leaflets alone. The following genera 

 contain forms in this region which show similarities with the fossil — 

 namely Enterolobium, Zygia, and Lysiloma among the Mimosaceae, 

 and Cassia, Caesalpinia, and Swartzia among the Caesalpiniaceae. 



Eolotype.— Oat. No. 36437, U.S.N.M. 



LEGUMINOSITES ENTADAFORMIS, new species. 



Plate 107, fig. 3. 



Leaflets elliptical in form, nearly equilateral in outline, widest in 

 the middle and about equally rounded at the apex and base, the latter 

 slightly broader than the former. Margins entire, regular. Texture
