(Figure 2). The dimeres on the left side of the specimen are much shorter 
than those on the right side, about 3 on the left corresponding to 2 on the 
right, but they vary in individual height. They are about twice as wide 
as those on the right, and their width is generally greater than their

height. They bear irregular transverse ridges, some on or across the 
sutures, as though connecting the ossicles, others half-way up the ossicle. 
The latter merge into the transverse ridges of the proximal region. The 
dimeres on the right are about three times higher than wide, and their 
outer edge is markedly concave. 
It is not easy to understand why there should be this great difference 
between the two sides of the stem in the median region and, in the absence 
of the theca, any suggestion would lack corroborative evidence. 
The specific distinctness of this form is accentuated by the facts 
now described, but its reference to Dendrocystis, though still probable, is 
not placed beyond doubt. If the discovery of further specimens were 
eventually to prove this species certainly congeneric with the genotype 
Dendrocystis sedgmcki , there would arise the question of adopting the 
prior name Syringocrinus. In my opinion such a change of name would 
be unfortunate and ridiculous. It must be clearly understood that from 
neither the description nor the figure of Billings, nor even from the 
holotype as now elucidated, can the generic position be inferred with 
certainty. Syringocrinus has never been diagnosed, and the generic name 
should not be considered available.
