IDENTITY OF SOME MARINE ANNELIDS—-HARTMAN 115 
has composite setae with a long, slender appendage (fig. 10, 7). 
Composite setae are continued through at least 26 segments in the 
last of which there are at least three limbate setae, two composite 
hooks, and three simple hooded hooks. The appendage of the com- 
posite hooks decreases in length posteriorly so that its length comes 
to be only about three times its width. More posteriorly (after the 
twenty-sixth segment) composite setae are gradually more or less 
completely replaced by simple hooks. Limbate setae may be absent 
after the sixtieth segment; none were observed after that.

Ficure 10.—Species of Lumprineris (enlarged) 
a-d, Lumbrineris acuta (U.S.N.M. No. 12882): a, Anterior end from left side; b, bilimbate 
seta from third parapodium; c, maxillary parts; d, hooded hook from a median- 
posterior parapodium. 
e-g, Lumbrineris heteropoda (Honshu, Japan): ¢, Tenth parapodium; f ,a median para- 
podium; g, a posterior parapodium. 
h, k, 1, Lumbrineris grandis (U.S.N.M. No. 5214): A, Maxillary parts from one side; , 
outline of an anterior parapodium; /, composite seta seventh parapodium. 
i,j, m, Lumbrineris parva-pedata: i, Outline of an anterior parapodium (U.S.N.M. No, 
16019); 7, fifth parapodium in anterior view (U.S.N.M. No. 19622); m, hooded 
hook from a median segment (U.S.N.M. No. 16019). 
In this specimen the third maxillary plate on both right and left 
sides is clearly bifid (fig. 10, A); the forceps are distinctly falcate. 
Parapodia are short, thick throughout; the postsetal lobe exceeds the 
presetal one. The latter are simply low, rounded, cushionlike or 
compressed; postsetal lobes are more or less acutely pointed, their 
length, however, no greater than their width (fig. 10, %). 
L. grandis has affinities with Z. japonica Marenzeller in having 
composite setae in anterior segments, and maxillary parts are sim- 
ilar. In Z. grandis, however, the parapodial lobes are much reduced
