105 ; 
oral side of the urn pennate, the partitions forming the line of 
divergence; marginal muscle a single ligulate ring, forming a con- 
tinous, thickened projectine frim to the urn, outside the tentacles 
and the anchors; selatiniform layer conspicuous, varying in thick- 
ness in the urn and pedicel. C. cyathiformis Sars. 
' Gen. dub. Depastrum Gosse. Distinguished by following fea- 
tures: disk octagonal; the tentacles spring from the margin or with- 
out it; no anchors. D. cyathiforme Gosse. 
Fam. Eleutherocarpidae. Each genital half, projecting 
freely into the discal camerae, extends in a direct line from the 
inner or axial end of a partition to or toward the end of an arm; 
the four quadrant camerae of the disk simple. 
Gen. Lucernaria Müll. Disk broad funnel-form;' the eight 
arms elongate, in closely approximated pairs, so that the oral side 
of the disk appears quadrate; pedicel monocamerous; tentacles in 
groups on the end of each arm; radial and transverse development 
of each group equal; marginal. anchors none; genitals transversely 
folded bands which extend to the end of the arms; muscles ‘of the 
pedicel four, equidistant, projecting like ridges or pilasters from 
the surface of the camera; the prineipal muscles of the disk ligulate, 
each one extending from the proximal end of a partiton to the end 
of an arm; marginal muscle ligulate, very thin at the base of the 
tufs of tentacles; gelatiniform layer thin in the disk, moderately 
thick in the pedicel. Lucern. quadricornis Müll. 
Gen. n. Calvadosia:.Cl. Disk infundibuliform; the eight 
arms nearly equidistant, prominent; pedicel monocamerous with 
four equidistant rounded pilasters: tentacles in groups on the end 
of thearms close to the aboral edge; outer row pistilliform and ha- 
ving the same function as the anchors in other genera; radial and 
transverse diameter of group equal; anchors none; genitals trans- 
versely folded bands extending to the end of the arms; the digiti- 
form bodies alone extend across the proximal end of the partition ; 
muscle of the pedicel a continuous,thin layer of transversely dispo- 
“sed fibrillae, forming a cylinder between the outer ad inner walls, 
and imbedded in the gelatiniform layer; the prineipal muscles of 
the disk ligulate, each one extending from the proximal end of the 
partition to the end of an arm; marginal muscle ligulate, modera- 
tely thiek, but. at the outer base of the tufs of the tentacles very 
thin; gelatiniform layer thickest at the edge of the disk, but thins 
out almost entirely half way toward the pedicel, and then in the 
latter grows thick again where it is divided into two layers or 
eoncentrie cylinders by the intervening museular cylinder; the four 
pilastres are also gelatiniform, and not muscular, as are the pila- 
sters in the pedicel of L. quadricornis. €. campanulata Lamx.
