PLATE III. 



iScHULTZICRINtS TYPUS, Sp. IIOV. 



Onondaga Group, Middle Devonian. Livingston Co., N. V. 



Fig. ](/. Anterior view of specimen with parts of the wide, simple arms, and proximal 

 columnals; the face of a dispUiced brachial exposing dorsal canal and ventral 

 furrow, and the ventral side of another higher up, showing sockets for covering 

 plates; also joint faces of several detached columnals. 



\lj. Posterior view of calyx and base of arms in same specimen; showing anal opening 

 through dorsal cup, with radials meeting above it. 



le, d. Ventral side of brachial, showing sockets for covering pieces, and end view. X 2. 



2. Basal view of calyx of another specimen, showing undivided infrabasal disk, and 



the quadripartite axial canal; the edge of the anal opening also visible. 



3. Basal view of much larger calyx, vertically crushed; showing undivided base and 



axial opening. 



4(1. Lateral view of specimen with part of arms and stem; showing the greatly pro- 

 jecting nodal columnals and thin iiitcrnddals. Note the very short first IBr 

 in this and the next two specimens. 



4h. An internodal columnal; and Ac, a nodal; ilctachcd I'nini the same specimen, 

 showing the central and four peripheral canals. 



5. Another specimen with stem, showing shorter intcrnodes; and arms with short 



first IBr; the calyx plates displaced. 



6. Another specimen showing extreme disproportion in length of first and second IBr. 



SCHULTZICRINUS (?) ELONGATUS, sp. IIOV. 



Onondaga Group, ^liddle Devonian. Livingston Co., N. Y. 



Fig. 7(1. Specimen with part of stem and arms, the latter much shattered and displiiced, 

 but showing that they were long, anil perhaps simple; the broad ventral furrow 

 and deep transverse section of brachials, perforated bj' dorsal canal, appear 

 at several places. 



7b. Cross section of column, showing tripartite axial canal. 



7c, (/, e. Dorsal, ventral, and end views of a higher ijrachial in same specimen, studded 

 with fine, sharp tubercles; showing the sockets for covering pieces and the dorsal 

 canal. X 2.

 Mus. Nat. Hist. New York. 

 86. Basal view of same, showing cjuadripartitc axial canal. 

 9. A smaller specimen, showing character of stem.
