The Echino derm ilia of jheiv Brunswick. 
Nothing is known of the development of this speeies and almost 
nothing of its habits. It seems to prefer muddy and shelly bottoms, is 
never found above low-water mark, and lives only in cold, clear water.

This is a very small but pretty and graceful Ophiuran. The disk, 
one-fifth of an inch in diameter, is covered with overlapping scales of 
about ecpial size, with a sharp line where those of the upper meet the 
projecting edges of those of the lower surface. The arms are about 
four-fiths of an inch long, slender and very flexible. The lower arm- 
plates are shield-shaped, the upper rounded and slightly separated by 
the encroachment of those of the side, which encroach more above 
than below. There are three short, blunt, nearly equal arm-spines to 
each side-plate, the upper of which is a little the stoutest. It is gen- 
erally gre}dsh in color, with occasional reddish markings, and 
found among broken shells, under which it hides itself. It pos- 
sesses special interest from the fact that it is viviparous. If old 
individuals be opened in August they will be found to contain several 
orange colored young. The eggs being protected within the body of 
the mother, their development is without a metamorphosis. 
This species has not yet been reported from the Gulf of St. Lawrence, 
but it ought to occur there, both in the deep and shallow parts, and will 
probably be found after further search.
