openings and similar articulations with those which are seen in the 
trunk itself. On the specimen described by Mr. Walch, he remarks 
that there also exist several mammillary projections, resembling small 
branches, and which, being placed over some of the openings which 
pass from the centre to the circumference, have these openings or 
holes continued quite through them. If, he observes, we have a 
right to suppose that similar little branches were placed over all 
these little openings, these branches must have been exceedingly 
small, and so prodigiously numerous, as to give it the appearance of 
a brush. 
The following differences, it must be admitted, serve to place these 
entrochi, and of course the encrinus to which they belong, under a 
distinct species. The width of the column appears to much exceed 
the width of entrochi in general ; the lines of articulation are much 
finer than in other entrochi, and are not so regularly disposed ; 
hence a degree of irregularity in the thickness, and in the figure of 
the trochites themselves, which is unknown in other trochite. From 
this discordance many had been disposed to consider these bodies ra- 
ther as mmified corals than as entrochi ; but Mr. Walch observes that 
they agree with these bodies in every essential circumstance, and 
therefore should be considered as the parts of the trunk of an encrinus, 
which, judging by the size of the stem, must have been of a very consi- 
derable size. If the stems of an ell in length, found by the limeburners 
of the Isle of Gothland, were but of the ordinary thickness, then, as 
Mr. Walch observes, the stems of such a thickness, or that which is 
possessed by the specimen, represented Fig. 6, should be, in proportion, 
of three ells or more in length. How much, he remarks, does there 
here remain to be discovered ! 
The exact accordance of the Gothland fossils with the stem of the 
Shropshire (the turban) encrinite, in the thinness of the trochitae, the 
fineness of their radiating lines, the numerous lateral openings, and 
the protruding processes, shews, indubitably, that these fossils* have all 
belonged to the same species of encrinite.
