166 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 10 



Simple hooded hooks replace composite hooks from about the six- 

 teenth segment; they are usually few in number (about 2, 3, or 4) and 

 are accompanied by 2 yellow acicula. A sixtieth parapodium has 3 simple 

 hooks and 2 acicula (pi. 12, fig. 265). The hooks have a larger basal 

 tooth and 5 or 6 smaller ones at the end (pi. 12, fig. 263). 



Mandibles are long, fused for most of their length, but the basal ends 

 are slender; the distal portion is broadly flaring (pi. 12, fig. 266). The 

 maxillary carriers are a little longer than broad, laterally incised, and 

 terminate basally in pointed ends (pi. 12, fig. 267). The forceps (maxilla 

 I) are falcate; maxilla II has 4 teeth on either side, and maxillae III and 

 IV have each a single tooth (pi. 12, fig. 267). 



L. cruzensis differs from nearly related species which also have pos- 

 terior bilabiate parapodia, anterior segments provided with composite 

 hooks, and acicula yellow, in that the proboscidial armature is different 

 and the posterior parapodial lobes are slenderer.

Lumbrineris pallida, new species 

 Plate 12, Figs. 270-274; Plate 13, Figs. 275-277 



Collections. — 1205-40 (about 15 anterior ends) ; 1245-41 (about 6 

 anterior ends) ; ?1131-40 (1 fragment). 



A small, translucent (preserved) form with large, red eggs is be- 

 lieved to represent an undescribed species. A slender piece of 84 segments 

 measures 26 mm long; another of 82 segments measures 24 mm long. 

 Large eggs are present from segment 31 to the ends of these pieces; 

 hence they are believed to be adults. As no specimens in the collections are 

 complete, the nature of posteriormost parapodia cannot be ascertained. 



The prostomium is broad, depressed, anteriorly rounded (pi. 12, fig. 

 272). The first few segments are sufficiently translucent that the pro- 

 boscidial armature may be seen through the body wall. Parapodia are no- 

 where conspicuous, but in anterior segments the setae extend laterally in 

 fan-shaped fascicles. Here also the postsetal lobe is broad, auricular, but 

 far surpassed by the laterally directed setae. A fifth parapodium has the 

 proportions shown in pi. 12, fig. 274; it is provided with 2 or 3 dusky 

 brown acicula, 2 superior limbate setae, 3 composite hooded hooks, and 

 2 inferior limbate setae. The presetal lobe is low, cushionlike. From about 

 the tenth to fifteenth segment, the postsetal lobe is gradually reduced in
