Gen. n. Craterolophus Cl. Disk octohedral, campanuli- 
form; arms produced; pedicelmonocamerous, the camera possessed 
of Bias which form a cruciate figure at, the base; tentacles in 
groups at the end of the arms; anchors none; Ban tubiform 
with blind-sacklike divisions; pedicel muskels correspond to the 
four ridges of the camera. (Der Stielist nach den Untersuchungen 
des Ref. ganz ohne Muskeln, wie denn auch die Geschlechtsor- 
gane sich nicht von denen anderer Lucernarien unterscheiden.)

Gen. n. Marania Cl. Disk urnaeform octohedral; the arms 
produced; pedicel monocamerous; the camera simple ; tentacles in 
groups at the end of the arms, but a little within the museular 
margin of the bell; outer or distal row pistilliform; the radial dia- 
meter of the groups greater than the transverse; marginal anchors 
pistilliform, situated just within the muscular margin; genitals 
transversely folded, terminating at, a greater or, less distance from 
the margin of the bell; the digitiform bodies accompany the united 
bands across the proximal end of the partitions; muscles of the 
pedicel four, equidistant, imbedded in the gelatiniform layer; prin- 
eipal muscles of the disk ligulate; from each side of the proximal 
end of a partition one extends in a direct line to the end of the 
nearest arm; marginal muscle ligulate; powerfull, forming a ring 
of uniform breadth and tickness, uninterrumptedly, all around the 
margin of the bell, just outside the anchors and the tufs of tenta- 
cles; gelatiniform layer variable in thickness in the bell, uniform 
in the pedicel.e M, auricula Fbr. Norwegen, Grönland. Maine. 
Gen. Cardwella Allm. Disk urnaeform, perfectly eireular; 
arms none; pedieel tetracamerous;' tentacles placed. in eight di- 
stinet equidistant groups within the margin of the urn, and ar- 
ranged in rows parallel to the margin, those in one row alterna- 
ting with those in the next and suecessively diminishing in size 
from the central to the outermost ones; the radial development less 
than the transverse; between every radial row the oral and aboral 
sides of the urn are united by a thin septum, so that the interior 
of the tentacles communicates with the “quadrant camerae of the 
urn, through short radiating passages; the marginal anchors are 
single tentacles whose cavity opens between a pair of septa like 
those of the base of the tentacles; they are set up higher and 
nearer to the edge of the urn than are the tentacles; the approxi- 
mated genital halves, with their respective claustra, extend half 
way or more toward the edge of the urn, transversely plicate; the 
digitiform bodies border the whole length of the bands; pedicel 
muscles four, alternate with the camerae; principal museles of the
