IDENTITY OF SOME MARINE ANNELIDS—HARTMAN 121 
Limbate setae are continued to the end, but absent from some para- 
podia. Perhaps this led Moore (1904, p. 491) to say that “by 50 
[uncini] are alone present to the number of 4 or 5 which is further 
reduced to two or even one posteriorly * * * the slender 
setae do not altogether disappear until about LX XV.” Actually, in 
these cotypes, as also in many specimens from southern California, 
some posterior parapodia continue to have limbate setae, to the 
posterior end. 
Ficure 12.—Species of Lumprineris and Armanpia (enlarged) 
a, b, g, Lumbrineris mooreit (U.S.N.M. No. 17403): a, A posteromedian parapodium with 
long setae; b, bilimbate seta from an anterior parapodium; g, a hooded hook from 
a posteromedian parapodium. 
c. d, Armandia agilis (U.S.N.M. No. 4898): c, Seventh setiger in anterior view, the 
branchia cut off at the dotted line, with long, presetal, dorsal lobe and rounded, 
postsetal, ventral lobe; d, parapodium from posterior third of body, in posterior 
view. 
¢, f, Lumbrineris minuscula (U.S.N.M. No. 5215): e, An anterior parapodium, in anterior 
view, setae indicated; f, a composite seta from an anterior parapodium. 
L. erecta is the commonest lumbrinerid with elongate, parapodial 
lobes, lacking hooded hooks anteriorly, in the intertidal of southern 
California. It occurs rarely as far north as Monterey. It has incor- 
rectly been confused with Z. heteropoda (see below). 
LUMBRINERIS HETEROPODA (Marenzeller) 
FIGuRE 10, e-g9 
Lumbriconereis heteropoda MARENZELLER, 1879, p. 30 (Miya Bay, Japan). 
The National collections contain specimens of what are believed 
to be this species, originating from Honshu Island, Japan. Since 
they differ notably from Z. erecta Moore (see above), with which 
the latter has sometimes been identified (Crossland, 1924, p. 4), and 
also since Marenzeller’s description seems to have been misinterpreted 
in some respects, the following remarks are added.
