Key to the Genera of the Subfamily Comasterinae. 
a.^ IIBr series 4 (3 + 4); further division series 2 (i + 2) or 2; proximal pinnu 
les more slender than the succeeding; terminal combs occur at intervals 
on the middle and distal pinnules (Andaman Islands to northern 
Australia, New Britain, the Philippine Islands, the Gil- 
bert [Kingsmill] Islands, southern Japan, and China) . . 
a' Some or all of the lIIBr and following division series 4(3 + 4); no divi- 
sion series 2(1 +2); proximal pinnules stouter than the following; termi- 
nal combs confined to the proximal pinnules 
b' IIIBr series 2; IIBr series 4(3-1-4); IVBr series in part or entirely 
4(3-1- 4) (northern Australia to west Java, the IMoluccas, 
the Philippine Islands, China and southern Japan) . 
b- .some or all of the IIIBr series 4 (3 -4- 4) 
c^ outer IIIBr series on each ray 2, inner 4(3-4-4); following 
series entirely or mostly 4(3 + 4) ; cirri only exceptionally 
present (Maldive Islands to northern Australia, 
New Britain, the Philippines, and the Caroline 
Islands) 
c'- IIIBr series usually all 4 (3 -f- 4); if IIIBr series of 2 are 
present there is no regularity in their occurrence (southern 
and southeastern Africa, Ceylon, and eastward to 
northern Australia, Oceania, and southern Japan) Comanthus 
d^ cirri few, small and weak, slightly if at all compressed 
distally, irregularly distributed on the centrodorsal, or 
absent altogether; one or more of the division series 
usually 2 instead of 4 (3 -f 4), but the division series of 
2 have no regular arrangement (Madagascar and 
Mauritius to Cej'lon, thence to northern 
Australia, New Caledonia, the Friendly, 
Tonga, Fiji, Samoan, Pelew, Gilbert [Kings- 
mill] and Caroline Islands, southern Japan,

d" cirri always present and numerous, well developed, late- 
rally compressed distally, evenly distributed about the 
periphery of the centrodorsal ; all the division series 
4 (3 + 4) (southern and southeastern Africa; 
Tasmania and southern Australia and north- 
ward to the Bay of Bengal, Samoa, the Mar-
