A single imperfect specimen of huge dimensions, including pro- 
stomium and 74 somites, was collected by Miss Robertson at Pleasant 
Beach in July, 1898. It is far larger than any specimen yet taken 
on the California coast. It measures 107 mm. in length (the en¬ 
tire worm must have been over twice as long) and 12 mm. in trans¬ 
verse diameter. The exposed surface of the elytra is rusty, with the 
exception of the first six pairs and scattered ones along the body, 
which are unpigmented and translucent.

12. Podarke pugettensis sp. nov. PI. 3, figs. 23-25. 
Body gradually tapering towards both ends ; somites 50-54, the 
anterior three or four (Fig. 23) much shortened ; the rest about 
four times broader than long. 
Prostomium twice as broad as long, three-lobed in front, the 
lobes bearing the tentacle and dorsal pair of antennae (Fig. 23). No 
palpi; antennae 4, the ventral pair considerably stouter than the 
dorsal, and provided with a thick basal segment. Tentacle small, 
subulate, less than length of head. Eyes 4, contiguous, anterior 
pair slightly larger and farther apart than the posterior; both pairs 
with lens ; retinal pigment brown. 
Tentacular cirri on first three segments, two pairs to each, with 
distinct basal joints; dorsal cirri of 2d and 3d somites equal and 
longest. 
Parapodia elongated (Fig. 24), exceeding half the width of dor¬ 
sum ; dorsal ramus and basal joint of dorsal cirrus fused ; ventral ra¬ 
mus much longer, terminating in a conical, achaetous tip; 2 aciculae 
in each ramus. Dorsal cirrus notably longer than the parapod and 
setae; gradually tapered; ventral cirrus extending obliquely back¬ 
ward, somewhat beyond acute tip of ventral ramus. 
tietae of two sorts, simple and compound, the former confined to 
the dorsal ramus; very few (Fig. 24) ventral setae, some with 
elongated appendages (Fig. 25) and some with short appendages — 
otherwise alike in form. They are arranged in a supra- and an infra_
