In the October measurements, which refer to specimens taken off 
the Shetlands, there appear to be four groups represented, the first by 
two specimens 83 and 87 mm.; the second ranging from 131 mm. to 
227 mm., the mean breadth being 187°6 mm, (72 inches) ; the third 
measuring from 235 mm. to 315 mm., the average width being 275-1 mm. 
(10}+2 inches), and one specimen of 364 mm. The November measure- 
ments from the Moray Firth represent two groups, one from 145 mm. 
to 219 mm., the mean width across the pectorals being 193-2 mm. (or 73 
inches), and one ranging from 233 mm. to 316 mm., the mean width 
being 280°5 mm. or 111 inches. If the limits of the groups are correct, 
the growth in width in a year would be about 3,4 inches in the October 
series and 33 inches in the November series; and probably this fairly 
well represents the actual growth of the starry ray.
