ing segments (fig. 35, e) on each side dorsally a stellate tuft and a 

 single, long spike hair anterior to it and arising from the same tubercle 

 or from a separate tubercle. Comb composed of four to eight scales 

 with pointed ends and basal denticles. Pentad hairs weakly developed 

 except for hair 1, which is a stellate tuft of 5 to 12 branches arising 

 from a basal tubercle ; hair 3 usually 4-branched ; 5 double or triple ; 2 

 and 4 usually simple. Siphon lightly pigmented, index 2.5, or less; 

 acus absent ; parallel-sided at basal fourth, then attenuated to about a 

 third of basal width at apex ; pecten teeth at most five on each side, 

 usually three or four, light in color, absent from basal half; an ir- 

 regular row of 8 to 10 dorsal hair tufts, each with three or four barbed 

 branches, about as long as width of siphon ; 10 to 14 ventral hair tufts, 

 the basal two are paired and 4- to 6-branched, remainder usually in an 

 irregular single row and with two or four barbed branches ; a strong 

 curved apicodorsal hair; ventral valve with a long 2- to 4-branched 

 hair. Anal segment with a small, black, incomplete saddle, posterior 

 margin with four or five small denticles ; saddle hair simple, stout, and 

 long ; ventral brush reduced to a pair of tufts, each with six to eight 

 very long, barbed branches; dorsal brush very long, hairs barbed, 

 ventral subcaudal tuft simple, dorsal with seven or eight branches; 

 gills longer than saddle hair, attenuated.
