GEORGE HODGE ON A NEW SAND STAR. 297 
Dise either pentangular or round, the former pertaining to 
well grown individuals, the latter to young. Upper 
surface of disc rosulated; under surface corresponding 
with the other members of the genus. Two clasping 
scales at the origin of each ray, each bearing above ten 
short spines. A crescent of eight or ten short blunt 
spines on upper surface of rays close to the disc. Lateral 
ray plates bearing five moderately long spines. Upper 
ray scales nearly square, slightly tapering towards the 
disc. Rays about four times as long as the diameter of 
disc, which in well grown individuals measures about a 
quarter of an inch. Colour reddish yellow, occasionally 
of a pale sandy tint. 
These features being so constant and distinct, there can be no 
doubt of the species under consideration being new to our fauna, 
and as such it affords me much pleasure to name it after my 
friend the Rev. A. M. Norman, who is, in fact, the original dis- 
coverer, having taken a single specimen some years ago in the 
Frith of Clyde, and at Shetland during 186i he also took three 
or four specimens, in both instances, however, they only received 
a glance, and were assumed to be the young of O. texturata, for 
which they may easily be mistaken unless subjected to micros- 
copical examination. 
This species would appear to be generally distributed, having 
been found at three widely different parts of our coasts. It is 
common here, between sixty and seventy specimens having been 
dredged here in a few hours, owing, however, to their excessive 
fragility, few were obtained perfect.
