Two specimens were taken in the trawl in from twelve to eighteen fathoms’ 
water on the western coast of Davis’ Strait, in lat. 70° ; they were both six- 
rayed, a variety which does not appear to have fallen under the notice of 
Muller, who mentions from one to live rays only. 
The specific name of Violacea seems particularly inappropriate to a species 
which varies so much in colour as the present ; individuals being found 
occasionally red, blue, grey, and even black ; those under description were 
rather red than violet. 
Asterias Polaris. 
A. pent.agona, pagina superiore tesselato-grenulata, margine articulato spinoso. 
Plate 1, fig. 2, 3. 
A single specimen was taken by a drag-net on the coast of Melville Island ; 
body plane, pentagonal, the sides lunate; margin obtuse, articulated, and fur- 
nished with a double row of small spines ; the articulations in number 150 are 
continued on the inferior surface to the grooves of the feet, the grooves 
being broad, with fleshy pectinate feet ; mouth central, simple ; back tes- 
selated with hexagonal superficial granulations, having in the centre a fleshy 
papilla, capable of being protruded more than three-tenths of an inch, but 
when retracted, appearing only as a central spot ; when viewed by a micro- 
scope, the papilla is seen to be furnished with minute and delicate vesicles.
