in place of the lower part of the reniform stigma. In the 

 grey-white or slate-white varieties, which seem confined to 

 the east coast, and are rare there, the markings are usually 

 neat, small, sharp, often abundant, the pale nervures edged 

 with darker and the lines and shades well but slenderly 

 marked ; more rarely these, following the example of the 

 brown forms, have the markings mainly obliterated ; but on 

 the north-east coast of Scotland they are sometimes found 

 much intensified and blackened. On the Lancashire coast a 

 form is not uncommon, of a dull pale umbreous with the 

 transverse lines and the upper stigmata indistinct, but the 

 claviform stigma, a spot before the orbicular, a square blotch 

 between it and the reniform, and a central basal streak all 

 blackish. All along our eastern coasts, in company with the 

 paler forms already described is a range of far more beautiful 

 varieties, having the ground colour smooth yellowish-brown, 

 or whitish-brown, shading off" to fawn colour, having a very 

 smooth creamy appearance from the absence of the usual 

 umbreous clouding. In these the dark crescents on the 

 collar are often black or deep brown, the transverse lines are 

 sometimes slenderly distinct, but more frequently absent ; 

 there is a broad white or whitish-brown straight stripe from 

 the base along the subcostal region, the two upper stigmata 

 are wholly white or but faintly clouded with brown, coalescing 

 with the stripe, the claviform stigma is distinct, edged, or 

 filled with brown or black, and the large squared spot 

 between the orbicular and reniform stigmata is either rich 

 dark brown, bright brown, or black ; very often also the 

 space beyond the reniform stigma is richly clouded with 

 fawn colour. Other specimens have the white subcostal 

 stripe joined to the two white stigmata, but are devoid of the 

 dark spots and clouding of fawn colour, and lean toward the 

 whitish -grey varieties. Others, more particularly from the 

 coast of Aberdeenshire and Kincardineshire, are most ex- 

 quisitely coloured, the markings just described intensified, 

 the subcostal stripe, the two upper stigmata, and the median
