416 PROCEEDINGS : BOSTON SOCIETY NATURAL HISTORY. 
Capillary setae (Fig. 120) alone present in first seven segments; 
obtusely angled, with striated limb on convex border, arranged in 
dorsal and ventral widely separated fascicles; persist in dorsal fasci¬ 
cles as far as 10th somite; beyond this point replaced entirely by 
uncini. 
Uncini (Fig 121) begin in ventral fascicles at 8th somite ; in dor¬ 
sal fascicles at the 10th ; hooded, with four minute teeth above ros¬ 
trum; shaft strongly geniculate. 
Length of 39 anterior somites, 36 mm. ; greatest transverse 
diameter of thorax, 1.5 mm. 
This species is represented in the collection by a single incom¬ 
plete specimen, lacking the posterior portion. It is an immature 
female, and was collected by Miss Robertson at Port Orchard, July 
2, 1898. The dorsal setae of the 8th and 9th somites appear to be 
entirely wanting. 
Chloraemidae. 
32. Trophonia papillata sp. nov. PI. 12, figs. 122, 123. 
Form rather long and slender, slightly tapered, thickest anteri¬ 
orly, abruptly diminishing toward mouth ; subcylindrical; interseg- 
mental constrictions distinct, but not noticeably deepened caudad ; 
entire surface papillate, slightly rough to the touch, but without 
adherent sand-grains; dorso-ventral differentiation slight, mainly 
expressed in differences between dorsal and ventral setae, and 
in the closer papillation of dorsum. 
Oral tentacles (Fig. 122) eight, of moderate length, pointed at 
tip; palpi (p .) thicker and blunter, grooved on ventral aspect, 
distinctly constricted at regular intervals. 
Setae of second, third, and fourth somites, both dorsal and 
ventral, elongated, flexible, capillary bristles, forwardly directed 
(Fig. 122), exhibiting the usual transversely-striate structure. 
Dorsal setae of remaining somites, capillary, three or four to each 
fascicle; ventral setae (uncini), to the same number; stouter than 
dorsal setae, blackish, hooked (Fig. 123). 
Somites of only complete specimen, 89 in number; those in the 
anterior region twice as broad as long; posteriorly, length and 
breadth gradually becoming equal. 
Length, 88 mm.; greatest transverse diameter, 4 mm. 
Two specimens, one incomplete, were collected at Port Orchard, 
July 2, 1898, by Miss Robertson.
