Our Crihrella lives upon the rocks and seaweeds about low-water mark, 
and on hard bottoms in deeper water. In moving, Prof. Agassiz points 
out (K) that it usually has three rays extended before it and drags the 
other two closely pressed together behind. In its development from 
the egg it passes through no free-swimming larval stage, but directly 
into the adult form. The young are carried about by the mother.

Distribution. («) General; — 30 to 150 fathoms. Cape 
Cod northward to Arctic Ocean. Northern Europe and Great 
Britain. 
{h) In N. B. Waters; — Grand Manan, off Duck Island in 
corralline zone, one specimen, Stimpson, (D). 
This, says Stimpson, is “by far the most elegant of our Starfishes”; 
and Forbes calls it one of the mo^t beautiful of the Starfishes of Britain. 
It is a pentagonal form and grows to be from nine to ten inches in dia- 
meter. The upper surface is covered with short, smooth spines, each 
of which is borne on the centre of a nearly circular plate. Around the 
margin of the upper surface there run two rows of plates which bear 
from one to three short spines. Along the ambulacral furrows are rows 
of spines arranged in pairs. In color it is generally bright red above 
and yellow beneath, Stimpson (D), thus describes his specimen; — “A 
large specimen was taken otf Duck Island, in the corralline zone. It 
was bright red above, and bright yellow below, being by far the most 
elegant of our Starfishes. The minute vesicles which protrude from the 
dorsal pores are short and tipped with black. The eyes are very dark 
red in color, and the suckers near them ai'e very long and slender, 
especially a single one fust above each eye.” 
Very little cf its habits and nothing of its development are known.
