arms, which to their full length are elevated prominently above 
the outer faces of the partition walls, so the latter are forming 
the bottom of a deep groove. Dorsal cup semi-globose, its lower 
concavity not larger than the width of the stem, and enclosing 
only the basals, which are hidden from view by the narrow, round 
stem. Plates not distinctly ornamented, merely showing a 
roughened surface. Suture lines slightly grooved. 
Radials rather large, as high as wide, rapidly sloping to the 
lower end; their lateral faces three times as long as the slanting 
upper; the superior face concave. First costals quadrangular, 
smaller than the radials, a little wider than high. Second costals 
hexangular, wider and higher than the first; their sloping upper 
faces longer than any of the others; the upper angle slightly 
truncated by the interdistichal. First distichal smaller than the 
axillary costal, the second less than half the size of the first and 
subquadrangular. Palmars three in the calyx, transversely 
arranged, rounded on the back. First interbrachials ten-sided, 
as large as the radials, longer than wide, widest at the middle; 
the two of the second row nearly three times as long as wide, 
rising to the hight of the third palmars. The interdistichal a 
little shorter and narrower than the two upper interbrachials com- 
bined. The walls forming the compartments taper gradually 
to near the upper end, then widening rapidly and curving ab- 
ruptly inward, so as to form a flat surface at the summit on a 
level with the tips of the arms. Arms rather short, very heavy, 
almost cylindrical. They rise above the sides of the partitions 
much more conspicuously than is known to be the case in any 
other species, their tips being lifted out from between them al- 
most completely.

Type in the Illinois State Museum. The species is named in 
honor of Dr. Josua Lindahl, the eminent zoologist and director 
of the state museum at Springfield. 
Callicrinus beaciileri W. and Sp. (nov. spec.) 
Closely resembling Excafyj^tocrinus. The calyx has the form 
of a wine bottle, with long slender neck and a deep concavity 
at the bottom, but the partition wajls, instead of forming closed 
compartments to the full length of the arms, rise only to a cer- 
tain hight, and are not closed from above. Hight of the calyx to 
the base of the tubular neck one-fourth greater than the width at the
