72 The Americati Geologist. February, 1900 
Dorycrinus pentalobus, (nov. sp.) 
Figs. 21-22. Side and basal view of the type specimen, natural size. 
The three basal plates are sharp and prominent and are 
excavated beneath for the column. All of the calyx plates are 
nodose. The first radials are six sided and wider than long. 
The second radials are four sided and twice as long as broad. 
All of the higher radials are broader than long. The plates 
in the interradial areas are arranged as usual in this genus — 
ont below, two above, etc. 
The plates of the azygous side can not well be made out 
as the fossil is not entirely free from the limestone matrix. 
Dome or ventral plates all strongly nodose. There is a strong 
central spine but no others. The anal opening is lateral as 
usual in this genus. The vault is quite as high as the calyx. 
The body is strongly lobed and this, together with the single 
spine and peculiarity of plates, are sufficient to identify this 
species. 
It occurs near the base of the Upper Burlington lime- 
stone at Louisiana, Mo., and White Ledge, Mo., and is very 
rare. 
Batocrinus (?) springeri, (nov. sp.) 
Fig. 16. Side view, natural size. Named in honor of Mr. Frank 
Springer, Las Vegas, N. M. 
The basal plates form a flat surface, only seen in a basal 
view and extending but little beyond the columnar cicatrix. 
The first radials and the first anal interradial are strongly 
nodose. The second radials are four sided and convex, form- 
ing part of a central radial ridge, but they are not nodose. 
The third or axiliary radials are five sided, nodose and each 
supports above two secondary radials. On these latter plates 
rest arm-bearing plates. The first interradials are strongly 
nodose and followed above by two very small pieces. Above 
the first anal interradial are two nodose plates and two small 
ones above the latter. The dome or ventral plates are all 
highly nodose and the ventral tube is strong and located cen- 
trally. The vault is higher than the calyx. The arm open- 
ings are four to the ray or twenty in all, directed outward and 
with a slight tendency toward grouping. The first radials 
would be taken for basals by a careless observer.
