226 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 7 



of 12 to 15 cones; area III with a broad patch of 10 to 12 smaller cones; 

 area IV with 18 to 24 tall cones disposed in a triangular patch, some of 

 which are heaviest on the maxillary ring, but along the inner side of IV 

 the cones are tiny ; area V with none ; area VI with 4 or 5 cones in a dia- 

 mond or 2 irregular rows ; areas VII and VIII with a row of larger cones 

 on the maxillary side and 2 or 3 rows of tiny cones on the oral side. In 

 one collection (900-38) some of the paragnaths are inserted on chitinous 

 plaques, much as shown by Fauvel (1914, pi. 14, fig. 6) for individuals 

 of A^. zonata Malmgren. 



Parapodia are typical except that in posterior parapodia the dorsal 

 lobe is notably reduced (pi. 35, fig. 52). Homogomph falcigerous noto- 

 podial setae are present from about the twentieth segment. The appen- 

 dage is slightly curved but lacks teeth. Heterogomph falcigerous neuro- 

 podial setae have a short, curved appendage, the basal part about as long 

 as the hooked end, with obscure spinelets along the cutting edge. 



In some specimens the peristomial ring is constricted, collarlike, much 

 narrower than the first podal segment, but about twice as long as the 

 latter. 



These specimens are referred to N. pelagica Linnaeus with some 

 doubt because of the character of the posterior dorsal lobe (pi. 36, fig. 

 61). 



Distribution. — ^Widely reported from littoral areas in all seas.

Nereis flavipes Ehlers, 1868, pp. 549-552, pi. 21, figs. 26-30. 



Collection. — 728-37. One individual. 



A single, complete individual, 40 mm long, has 71 setigerous seg- 

 ments. It agrees reasonably well with the description by Ehlers (1868, p. 

 549) for the type from the Adriatic Sea. Posterior notopodial lobes are 

 enlarged ; the lobe ventral to the attachment of the dorsal cirrus is pro- 

 duced as a triangular elongation (pi. 35, fig. 51). Homogomph falcige- 

 rous notopodial setae are present from the nineteenth segment. They have 

 a smooth, falcate appendage (pi. 35, fig. 49). Neuropodial falcigerous se- 

 tae have a short appendage, with delicate spinelets (pi. 35, fig. 50). 



The proboscidial formula is as follows : area I with 2 unequal cones 

 in tandem; area II with a double row of small cones; area III with none; 

 area IV with about 1 5 cones in a crescentic patch ; area V with none ; area 

 VI with 6 or 7 taller cones in 2 rows ; areas VII and VIII with very many
