In lieu of measurements the plates can be examined. They 
yield the proportions as far as these can have value in comparing 
species. There need not be the least hesitation, however, in 
assigning a new species. Reference to the description of the 
Cycadeoidea Uddeni 1 shows three or four times as heavy a devel- 
opment of ramental chaff in the Texas form of comparable age, 
with variation in leaf base outline. All this suggests generic 
rather than specific remoteness. The Black Hills Cycadeoidea 
Stillwelli, already mentioned, is a cycadeoid type with piauciform 
ramentum, and much closer, perhaps as close as any known 
American specimen. But decided difference in the thickness of 
the armour and greater age, without details concerning fructi- 
fication in either case, at once compel separation. 
Cycadeoidea Boesiana sp. nov. 
Plates XI and XII 
Type, a low, rather small, quite complete, well-silicified trunk 
with a good terminal bud. Reposed with the Yale col- 
lections. Found by Dr. Emilio Bose, along with much 
petrified wood in the lowermost Cretaceous of Wise county, 
Texas (near Bridgeport) about 60 miles northwest of Fort 
Worth. 
Only a preliminary notice of the fine stem shown in the 
plates is conveniently given here. It is intended to follow with 
a histologic study in a continuation of the volumes on the 
“American fossil cycads ” now in course of preparation. The 
specimen is one of the squamous forms resembling the Isle of 
Portland “crows' nests,” but of better conservation. It has 
nearly the diameter, and about half the height, of the Potomac 
Cycadeoidea marylandica. To this form there is the greatest 
resemblance, and if found closely associated, there would be 
need to question whether the minor differences might not better 
be called varietal. 
As found well to the southwest, however, the fact that the 
leaf bases average far smaller than those of C. marylandica or 
that small scale leaves were much more numerous, may be
