The radials are slightly broader than long, in lateral contact throughout their entire 

 length; their interradial angles are somewhat produced. Proximally the radials are slightly 

 rounded dorsallv. becoming more strongly rounded distally, especially at the sides. so that at

 lencrth is half again as great as the median length. due to incision by a process trom the 

 axillary. The lateral edges are straight, diverging somewhat, and entirely free. 



The axillaries are rhombic, the lateral angles slightly truncated and continuing the 

 direction of the lateral edges of the IBr,: the anterior angle and the posterior process incising 

 the IBr, are about equally produced, and are similar; all tour edges are slightly concave. 



The first brachial is wedge shaped, with the proximal and distal edges slightly concave, 

 and is about as broad as the external (greater) length; the internal length is not much more 

 than half the external length: the internal edges are entirely free. The second brachial is larger 

 than the first, irregularly quadrate. The third brachial is nearly twice as long interiorly as 

 exteriorly, about as broad as the exterior lenght.'The arms are not preserved beyond the 

 syzygy between the third and fourth brachials. 



The length of the specimen from the tip of the centrodorsal to the syzygy between the 

 third and fourth brachials is 9 mm.
