one hereinafter defined. With these, there are eight specimens of 
Actinocrinus, belonging to six different species, two of which are here- 
inafter described, one cast of a Dorycrinus, and one Dorycrinus which 
is defined, and also numerous fragments of crinoid columns. 
ACTINOCRINUS DALYANUS, 0. Sp. 
Plate VII., fig. 1, view of the azygous side, natural size; fig. la, view of the posterior or 
side opposite the azygous side of another specimen, natural size. 
Body below the arms, turbinate, truncate at the base, summit conical 
and produced into a proboscis. The general form is much like that of 
A, celatus, though the base is not-so broadly truncated. 
Basals.—Basal plates twice as wide as high, and thickened at the 
base. 
First radials.—First radials about as wide as high, two heptagonal, 
and three hexagonal, 
Second radials.—Second radials wider than high, three of which are 
pentagonal, and two hexagonal. 
Third radials.—Third radials a little wider Gham high, hexagonal, 
and supporting upon each of the upper sloping sides a single secondary 
radial. 
Secondary radials.—The secondary radials are short, pentagonal, 
and support upon each of the upper sloping sides a single brachial plate 
from which the free arms arise. 
Regular interradials.—Regular Tatornawinls four, the first heptag- 
onal or octagonal, about the size of the third radials, succeeded by two 
smaller plates, and these by a single plate resting between the second- 
ary radials. 
Azygous interradials.—The first azygous interradial is hexagonal, 
of about the same size as the first radials. It is succeeded by two 
plates, and these by three, above which only a single plate appears to 
occur. : 
Arms.—Arms twenty. 
Surface.—The surface is ornamented with a tubercle in the central 
part of each plate, from which a ridge radiates toward the middle part 
of each of the sides, uniting at the sutures with like ridges from the 
adjoining plates, thus forming a stellate and tuberculous decoration. 
The summit is covered with numerous papilliform, polygonal plates. 
The specific name is in commemoration of Mr. George Daly, late 
manager of the Lake Valley silver mines, and a noted mining engineer 
of superior endowments. He was killed by the Apache Indians.
