248 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 7 



Glycera papillosa Giube 



Glycera papillosa Grube, 1856, pp. 176-177; Ehlers, 1901, p. 154; Kfn- 

 berg, 1910, p. 58, pi. 21, fig. 3; Augener, 1922, pp. 203-205, fig. 9. 



Collection. — 376-35. One specimen. 



Length of a nearly complete individual is 20 mm for about 85 seg- 

 ments. The characters agree well with the redescription by Augener 

 (1922, pp. 203-206) except that the proboscidial papillae do not have a 

 subterminal constriction. The dorsal cirri are inserted high above the 

 parapodial bases. 



Distribution. — Chile; Peru. In depths to 20 fms.

Glycera oxycephala Ehlers, 1887, pp. 121-123, pi. 41, figs. 7-11. 



Collections.— 1^6-3^, 887-38, 889-38, 914-39. 10 specimens. 



Length of 115 segments is about 70 mm. Segments are biannulate, the 

 parapodial ring the longer; anterior segments have a faintly marked third 

 ring. The prostomium is a long smooth cone, or faint annulations are vis- 

 ible at the sides. The terminal antennae include 2 shorter and 2 longer, 

 the latter about twice as long as the former (pi. 43, fig. 124). 



The proboscis (everted) is more or less closely covered with elongate 

 papillae of one kind (pi. 43, fig. 122). The terminal jaws are stout, black, 

 strongly falcate (pi. 37, fig. 74). The accessory piece differs from that in 

 G. capitata in that the basal piece is longer than broad, and the secondary 

 tooth is absent (pi. 37, fig. 75). 



Parapodia have 2 presetal and 1 postsetal lobe. The presetal lobes in 

 the anterior region are long, bluntly rounded distally, the dorsal extend- 

 ing distally as far as the ventral (pi. 43, fig. 123). More posteriorly the 

 dorsal lobe is progressively smaller, but even in posterior parapodia (eigh- 

 ty-fifth) the 2 lobes still surpass the postsetal lobe (pi. 44, fig. 125). Dor- 

 sal cirri are inserted low, near the dorsal base of the parapodia. 



Ehlers (1887, p. 121) described G. oxycephala from collections made 

 by the Blake Expeditions. The locality was given as doubtful. Ehlers was 

 able to attribute only 2 prostomial antennae to it, saying, however, that 

 the other 2 might have become lost. In the specimens herein reported, the 

 4 antennae are of unequal sizes (pi. 43, fig. 124), but clearly visible. 



These specimens dififer from Ehlers' description in that (1) the pro- 

 stomium has 4 antennae instead of 2, (2) the aileron differs from that in
