IDENTITY OF SOME MARINE ANNELIDS—HARTMAN 123 
body segments have parapodia with prominent postsetal lobes which 
come to have the form of long, fingerlike processes, bending abruptly 
upward nearly at right angles, rising above the back. 
One other species merits consideration in a discussion of this group, 
L. sarsi Kinberg (1865, p. 569) from Guayaquil, Ecuador. The type 
has greatly elongated posterior, postsetal lobes, but here the anterior- 
most parapodia, from the first, have some simple hooded hooks, ac- 
companied by limbate setae.

Ficure 13.—Species of Lumprinerts and ARABELLA (enlarged) 
a-c, Lumbrineris zonata (Kodiak Island, Alaska): a, Hooded hook from first setiger, showing 
long hooded region; b, distal end of same hook enlarged; c, one of five hooded hooks 
from a posterior parapodium, showing distal hooded region. 
d, Arabella iridescens (U.S.N.M. No. 5216): Part of maxillary apparatus in dorsal view. 
In the original description of this species, it is stated “setae 
* * * of two forms: winged capillary in anterior portion of the 
body and hooded crotchets in the posterior region,’ implying that 
hooded hooks are absent in anterior segments. I have again 
examined the type of Z. zonata (at the Museum of Comparative 
Zoology) and verified the presence of simple hooded hooks in at 
least the second setiger (setae of the first are broken away near 
their base). 
In many specimens examined, from Puget Sound south to southern 
California, the presence of simple slender hooded hooks (fig. 13 a, 6) 
already from the first setiger, has been ascertained. After about 
the thirtieth or fortieth segments, these slenderer hooks are gradually 
replaced by heavier simple hooks (fig. 13, ¢) with shorter sheath. 
In most individuals limbate setae are entirely lacking in far posterior
