long as broad, with the distal dorsal angles slightly produced. The distal "pinnules are S mm. 
long with 17 — 19 segments most of which are about three times as long as broad, smooth 
and cylindrical, without produced or s|jinous distal ends. 
In life this individual was banded light lavender and light yellow, the bands being from 
3 mm. to 4 mm. in width, thus resembling strongly Pcctinovteti-a jlavopit7-purca\ the colour in

ending distally somewhat abruptly in a strong stout point; it 
is composed of 11 — 15 (usually 12) segments, of which the
