more or less rounded patches side by side occupying the basal 

 part, across the middle portion two similar patches and, near 

 the apex, one large patch ; the two patches across the median 

 part sometimes coalesce and form a transverse band, but there 

 are transitional stages in which they retain their round contour, 

 yet meet each other by throwing out each a narrow projection ; 

 in some cases the first, or basal, pair also show a tendency to 

 coalesce, and in other examples they are actually joined ; the
