Sp. Char. Ciilyx fire millimetres high up to the articulation of the second radials, 
and marked by strong longitudinal ridges, of which two are radial in position, and two 
interradial ; the latter fork about the middle of the calyx, and the two branches of the 
fork are continued right and left to the articular facets on the radials. Prom these 
parts, therefore, three ridges proceed downwards, a radial one, and the right and left 
branch, respectively, of the interradial ridges on either side of it. The position of the 
hasi-radial sutures is very obscure, but there seem to be indications of them at a 
comparatively short distance from the upper edge of the calyx, so that the radial plates 
Would be relatively short, and the base high. The second radials are short, transverse, 
and oblong, but not as wide as the first radials ; the third radials, or axillaries, are a 
trifle longer, and pentagonal in shape, each bearing three arms j the outer remains 
undivided, but the inner one consists of two joints (or first and second distichals), the 
second of which is axillary, and bears two arms ; the latter are composed of relatively 
long and rounded quadrangular joints, with delicate pinnules. The stem consists of 
numerous discoid joints, three or four of which are larger than the others, and bear 
whorls of cirri. 
Ols. This very interesting Crinnid is represented only by an impression on the 
surface of a piece of hard sandstone, and from which casts have been taken. The base 
IS possibly dicyclic, but on this point the cast affords no definite information. The stem, 
so far as preserved, is 1 jiig, and there are thirty-five interuodal joints below' the two 
lowest whorls of cirri, and about twenty in the next internodo above. 
The rather obscure state of preservation renders the reference of this Crinoid to 
^oieriocrinus open to doubt ; it is, however, believed to belong to that genus. Many 
species of the latter appear to have whorls of cirri on the stem joints, e.specially near the 
I'Op of the stem. The same is the case in Hystricrinus, Ilinde, some species of 
^elemnocrimis, and a few other types. The only Neocrinoids with whorls of five cirri 
ure the Bentacrinidas. 
I have much pleasure in as.sociating with this interesting species* the name of 
the late Mr. J ames Smith, of Rockliampton, who was instrumental in bringing to light 
Uiany new fossils from that district.

Ohs. IN’umerous impressions of stems, quite indistinguishable from those of this 
laracteristic European Carboniferous species, were obtained by the late Mr. James 
®iith, associated with Fenestella and Brotoretepora. 
One s])ecimeu represents a portion of a stem, eight inches long, with a large 
’^^luber of strong cirri given off at close intervals. 
Impressions of Crinoid stems appear to be very common in the Penestella Beds 
^^ound Stanwell, in all stages of preservation, and many good examples were collected by 
Smith. 
* I am indebted for several suggestions on this spiecies to the late Dr. P. H. Carpenter, F.K.S.
