192 SEA SNAIL. 



brown; light on the belly. The back and sides ornamented 

 sometimes with longitudinal waved stripes of a light tinge, edged 

 with tints of blue; but soon after being caught the colour is 

 said to change and grow pale. The Rev. Mr. Holdsworth 

 informed me that of three examples he had met with two were 

 covered with narrow longitudinal lines as usually described, but 

 the third was blotched all over with white on a very dark 

 ground, not unlike some individuals of Coitus huhalis.
