xo, 1608. | NEW SPECIES OF CRINOIDS—CLARK. 933 
tenth, and fourteenth and fifteenth brachials, and distally at intervals 
of three bifascial articulations. | 7 
The pinnules appear to be similar to those of 7’. ds¢s, but the genital 
gland on the second is much larger, and occupies the fourth to the 
eleventh joints. 
Color.—Grayish brown, the skeleton dull white. 
Type.—Cat. No. 22681, U.S.N.M.; from Albatross Station No. 
5032; in Yezo Strait; 300 to 533 fathoms. 
BATHYMETRA MINUTISSIMA, new species. 
Centro-dorsal rather small, hemispherical, the dorsal pole fur- 
nished with several rather long spines; the cirrus sockets arranged in 
3 crowded columns of usually 3 each in each radial area. 
Cirri about 45 in number, 4 mm. long, with 12 to 15 joints; first 
joint rather less than half as long as wide; second joint over twice 
as long as its proximal diameter, flaring rapidly from about the 
middle so that the diameter of the distal end is nearly twice that of 
the proximal; third and following joints very slender and greatly 
elongated, expanding in each direction, but especially distally, into 
large flaring ends; fourth joint similar; the following joints 
eradually decrease in length, the proximal ends becoming less and 
less enlarged, but the distal ends remain enlarged and funnel 
shaped; antepenultimate joimt over three times as long as its proxi- 
mal diameter, expanding from the base to the tip, but more rapidly 
in the outer two-thirds; penultimate about twice as long as broad, 
with a long triangular opposing spine arising from the whole of 
the. dorsal surface, and nearly as long as the distal diameter of this 
joint; its distal edge is perpendicular to the long axis of the joint; 
terminal claw moderately slender, curved, about equal to the penulti- 
mate joint in length. 
Radials rather short in the median line, but strongly produced 
interradially, the anterior border being very strongly concave; the 
anterior interradial projections do not separate the first costals, 
which are very short, the lateral edge, which is about twice as long 
as the leneth in the median line, being not much more than one- 
third of the width; the distal border is broadly fringed with fine 
spines, and the dorsal surface is finely granulose; costal axillaries 
rhombic, broader than long, the edges, especially the anterior, strong- 
ly concave; the dorsal surface is finely granulose, and fine spines 
are developed laterally; costals and first two brachials on the out- 
‘side, and first three on the inside, in close apposition and flattened lat- 
erally, with very finely spinous lateral borders. Ten arms 13 mm. 
long; first brachial short, the outer edge rather longer than the inner, 
strongly concave anteriorly, the anterior border with a strong fringe
