into two main rami which give off ramules, sometimes approaching pinnulation. 
It also has the RA small, rhomboidal, in the oblique position. RR facets curved, 
less than width of plate. Our specimen unfortunately lacks the calyx, but the 
set of arms figured has a facies not dissimilar to that of the English species 
B. ramosus, but the arms are more slender and brachials longer. The ramules 
are long, and in turn bear pinnules which are apparently confined to the side 
next to the main arm. No other specimen was found. 
Two species from the Waldron shale described by Hall from the calyx only as Dendro- 
crinus nucleus and Cyatlwcrimis polyxo, have been referred to Botryocriniis, and I am 
figuring a calyx perhaps of the latter, from Hartsville, Indiana, seen from the anal side, to 
show the type which might be expected to go with these arms, plate 31, figure 10. 
Horizon and locality. Beech River formation ; Decatur County, Tennessee.
