(lcscril)iiif^ it us Cecropia TieerU,^ whicli, iii so 

 far as comparisons are p()ssil)lc, is very (-lose to 

 tlu' form under discussion. Another species 

 lias been descrii)ed ])y tliis auti^oi' from tlie 

 same horizon, and iu> ;dsii i-ccords - a species of 

 Cecropia from the lower Kocene (Yprc^sian) of 

 Alum Bay, England, which unfortunately was 

 never described or figured. 



The present form appeal's to \w represented 

 by similar fragmentary materiiJ in the Mid- 

 way (?) formation of Earle, Tex. 



Occurrence. — Holly Springs saiul, Holly 

 Si)rings, Mai"shall County, Miss, (collected by

Genus PAL/EODENDRON Saporta. 



PALiEODENDROv AMERiCANUM Berry, n. sp. 

 Plate XXXVIII, fisuie 1. 

 Description. — Ixvaves oblanceolate in outline, 

 apex obtusely pointed, and base narrowed and 

 decurrent. Texture very thick and coriaceous. 

 Length about 7 centimeters. Maximum width, 

 in the middle pai't of the leaf, al)out 1.5 centi- 

 metei-s. Margins entire. Petiole not jjresent 

 as a distinct luiit below the narrowly di^'urrc^nt 

 basal margins of tlie lamina. Midrib wide 

 and channeled, curved. Secondaries tiiin, im- 

 mei-sed in the thick leaf substance: about 10 

 irregularly spaced paire, diverging from tlie mid- 

 rib at wide angles, 60° to 80°, curving slightly 

 outward and then upward, relatively straight 

 to the vicinity of the margins, where they curve 

 upward to form a flat arch, approximately 

 parsxllel with the margins, joining the adjacent 

 superior secondary. Tertiaries obsolete. 



This species has a very distinct individuality 

 and closely resembles the supposed proteaceous 

 leaves describiul l)y Saporta from the Tertiary 

 of southeastern France. It is especially like 

 Palscodcndron (/;/psoph!Ium Saporta^ of the 

 Sannoisian of Aix, wliicli that author compares 

 with the living Protea caulescens and with the 

 fossil Covosperrnum macrophi/Uum of Ettings- 

 hausen. Saporta^ subsequently redescribed 

 this species as Quercus palseophcUos, a disposi-

tioii ill wiiicli I can not at all concur. It is 

 uidike any of the other mendiers of ilw Wilcox

 type still living in tll<^ American Tropics I have 

 failed to discover such a on<'. and iiave felt con- 

 strained to refer it to Sa])orta's genus, with 

 whicii it is so closely allied.

Genus PROTEOIDES Heer. 



Proteoides wilcoxensis Berry, n. sp. 



Plate XXXV, fisures 4-6. 



Description. — Leaves of different sizes, lance- 

 olate and commonly falcate in general outline, 

 ta])ering al)ruptly from about the middle to the 

 narrowly acuminate tip and to the equally 

 narrowly pointed decurrent base. Length 

 ranges from 6. .5 to 11 centimeters. Maxinuun 

 width, about halfway between the apex and the 

 base, ranges from 1.2 to 3 centimeters. Mar- 

 gins entire, full and in some specimens undulate 

 and unsymmetric. Texture coriaceous, the 

 substance of the leaf commonly preserved. 

 Petiole short and very stout, winged by de- 

 current lamina of leaf almost or entirely to the 

 thickened base. Midrib very stout, especially 

 proximad, generally curved, rather prominent 

 on the lower and channeled on the u])per sur- 

 face of the leaf. Secondaries numerous, thin, 

 diverging from the midrib at a wide angle, 

 camptodrome, as a nde almost obsolete by im- 

 mei-sion in the substance of the leaf. 



This species is common at both the Grenada 

 and the Puryear localities, where it occurs m all 

 sizes. Its affinities appear to be with the Pro- 

 teaceae, and it is similar to and probably filiated 

 with some of the Upper Cretaceous species of 

 Proteoides described from southeastern North 

 America. Its generic relationships among the 

 recent Proteaceji? is not dettM-minable with cer- 

 tainty and it is tlierefore referred to the form 

 genus Proteoides. Etting.shausen '' records a 

 sp(!cies based on a fruit from the Ypresian of 

 the Isle of Sheppey, and the leaves of anotlier 

 species from this same horizon at Alum Bay, 

 England."
