spiracular spines, X 335 ; h, larva, anal plates, X 440 ; i, adult female, anal plates, X 165 ; 
j, larva, leg, X 335 ; k, marginal flabellse of younger adult female, X 335 ; l, same, of older 
adult female, X 335 ; m, larva, antenna, X 335. 
found in some other species ; marginal third or a little more of 
the dorsum divided into large plates by thin transparent lines 
through the derm, the resulting arrangement at the margin 
somewhat similar to that found in Eucalymnatus tessellatus; 
antennae small, 6-segmented, average lengths of the segments 
about as follows (in microns) : I, 18; II, 14; III, 46.5; IV, 18; 
V, 17 ; VI, 27 ; the third segment nearly twice as long as any 
other; antennae sometimes even more reduced than indicated by 
the preceding measurements, and some of the joints indistinct or 
apparently wanting; legs present, but much reduced, approach-
