 two columns of cirrus sockets in each radial area are separated from those in 

 the adjacent radial areas by shallow rounded furrows averaging about half as 

 broad as the sockets-, the two columns are separated from each other by a line 

 rather less than half as broad as the furrows separating the pairs; 27 — 35 cirrus 

 gpnents, of which the longest are four times as long as broad or even longer, 

 and the terminal ten are as long as, or slightly longer than, broad (Philip-

 two columns themselvs are separated by a similar, but narrenver and shallower 

 furrow; 35 -411 cirrus segments, of which the longest are not over three times 

 as long as broad, and the outermost are all markedly longer than broad
