with the second, so that the accordance of the off-shoot with its 
parent (at least in the Giessen larve) by no means appears to 
be so complete as was affirmed by previous observers and also quite 
recently by Von Siebold*, who has received a number of the larvae 
for examination from Meinert. 
The species to which the larva belongs can only be determined 
hereafter, when we have the sexual animal before us. For the 
present we can only say that it is different from Wagnev’s species 
(with which, according to Siebold’s statements, Meinert’s species 
is 1dentical). 
XX.—WNotice of Torynocrinus and other new and little-known 
Fossils from the Upper Greensand of Hunstanton, commonly 
called the Hunstanton Red Rock. By Harry Sre ey, Ksq., 
F.G.S. 
THE curious new crinoid genus here described was one of the 
first found of the Red-Rock fossils. One species, chiefly known 
from the separated joints of the column, is the Apiocrinite of old 
writers onthe Hunstanton section; while the other, rarer and 
more obscure, with a column fused into a rod, has passed unno- 
ticed. This latter, which is the type species, commonly occurs 
as short fragments of a slender cylindrical stem of uniform 
thickness, and broken at both ends. But in the Woodwardian 
Museum there may be seen three examples of the head, several 
of the base, one of a dichotomous stem, and some showing the 
coluinn to consist of thick joints. On these data the genus is 
founded. 
The calyz, like the column, is soldered into one mass, and is 
inseparable from the stem, on the side of which it 1s placed, exactly 
like the bowl of a ladle, at right angles to the usual position, 
instead of being at the summit of the column. It is relatively 
small, hemispherical exteriorly, smooth, and, as in Millericrinus, 
appears to be made by two circles of five plates each (with the 
addition, I think, of five interradials). The cup is relatively large, 
with well-marked radiating vascular impressions. In each of 
the five compartments of the narrow brachial margin there 
are, on the inner part of the plate, two articular facets for arms. 
In one example, three of these compartments are confluent 
and regular, but the other two are irregular and separated by 
calcareous interspaces. In Hugeniacrinus the calyx is some- 
times set obliquely on the column, but in no other crinoid except 
the Paleeozoie Cheirocrinus has it the singular spoon-like position 
shown in the specimens described.
