Diameter of disk 5 mm, length of arms 4—5 times the dia¬ 
meter of the disk. The scales of the aboral side of the disk rather 
coarse, somewhat irregular, round the radial shields more regular, 
imbricating; the primary plates are distinet. The radial shields are

small, only ca. Vs of the disk radius; they are diverging, com- 
pletely separated by several irregular scales. The oral side of the 
disk has a complete covering of very fine scales. The oral papillæ 
are large, oval, not spiniform; sometimes a very small papilla is 
found distally to the large papilla. The oral shields are almost 
rhomboidal, wiih only a small outer lobe. The adoral shields do not 
ineet within and, as a rule, do not reach the genital slits. The ven- 
tral plates are about equally wide and long, with their lateral and distal 
edges slightly coneave and the outer corners rounded. Two small tent- 
acle scales. The dorsal plates are in the proximal part of the arm 
somewhat elongate, fanshaped, about as long as wide, farther out 
more oval, nearly twice as broad as long. The armspines are short, 
outstanding, distinetly flattened; there are six, sometimes seven, in
