236 JOURNAL OF ENTOMOLOGY AND ZOOLOGY 



Prostomhiiu, about as wide as long, slightly constricted at base, 

 widest slightly behind anterior pair of eyes. No fissure behinci the 

 insertion of median tentacle. Eyes, four; anterior pair well for- 

 ward, further apart, and much larger than posterior pair, which 

 are almost under the lip of the peristomium. 



Antouue, ciorsal, and peristomal cirri smooth, cylindrical, of 

 moderate length and quite bulbous at tip. Tentacle twice as 

 long as antenna?, and of a similar shape. All tentacles and cirri 

 have dark band just below bulb and another near the midcile. 



Peristomial parapodia small, achaetous, composed principally of 

 the ceratophores. Ventral cirrus conforming to the dorsal type. 



Second parapodium with two fascicles of ventral sectas, differing 

 from the typical in having a longer spinous section. Dorsal ramus 

 very small, equipped with a half dozen minute slencier setae, smooth 

 sharp and straight. 



Typical parapodia (tig. 5), distinctly bi-ramous. Neuropodium 

 thickly conical, truncate, fleshy, powerful, wrinkleci, carrying two 

 fascicles of ventral setae. Notopodium thick, short, somewhat 

 rounded at the end, anci carrying a flaring bundle of dorsal settE. 

 Ventral cirrus short, pointed, and subulate. 



Seta of four kinds, short dorsal setae, slencier, straight and 

 serrate (Fig. 10) ; long dorsal setae, strong, straight, sharp, some- 

 what hastate, but without the least sign of serrations (Fig. 9) ; 

 superacicular ventral sets with about ten spinous serrations, most 

 prominent distally, long hooked point and strong shaft (Fig. 6) ; 

 sub-acicular ventral sets, of the same type, but serrations dis- 

 tinctly less prominent (Fig. 7). 



Segmental eminences prominent thruout. Nephridial papillae, 

 cylindrical and fluted, begin on the eighth segment and continue to 

 the twenty-fifth. 



Elytra, large, varied in shape from reniform to ovoici. Heavily 

 pigmenteci with black and brown and have prominent white conical 

 tubercles distributed irregularly over the surface, the larger ones 

 tenciing to be in the center. Elytra non-ciliate. 



Coloration white with brown and black pigmentation on the 

 elytra. Some specimens show a distinct redciish tinge. Dorsally 

 there is a prominent intersegmental black spot. Prostomial and
