NO. 3667 POLYCHAETES—BANSE AND HOBSON 290 
In our material, the occipital tentacle inserts at the level of the 
first parapodium. The dorsal sense organ reaches the twenty-sixth to 
thirty-fourth setiger (average 29, S.D. 3.7, n=6). The first occurrence 
of genital pouches ranges from the twelfth to twenty-eighth setiger 
(average 20, S.D. 4.5, n=13). In the largest animals, which are 
mature females, neuropodial hooks start at the forty-eight and sixty- 
second setigers; hooks occur in more anterior segments (thirtieth to 
thirty-fifth) in younger animals. In view of this variability we include 
our material, for the time being, in L. cirrata in spite of differences 
in the shape of the hooks. 
BEgg-carrying females are dark reddish-brown. The largest anterior 
fragment, with 62 setigers, is 5.5 cm long and 3.5 mm wide, without 
parapodia. The diameter of eggs taken from the coelom is slightly 
larger than 200u, similar to Swedish material of both forms. 
A juvenile animal had been regenerating the prostomium and five 
anterior setigers. The U.S. National Museum has an uncataloged 
adult specimen, also regenerating the anterior end. 
Found at stations 1-4 and 6-8.

Not Laonice japonica.—Monro, 1933, p. 1047. 
We consider L. japonica to be a species separate from L. cirrata 
(Sars), as suggested by Monro (1933), because of the beginning of 
genital pouches at the fourth to fifth steiger. Also, the dorsal sense 
organ reaches only to the eighteenth steiger in the holotype of L. 
japonicus (Acad. Nat. Sci., Philadelphia, type no. 1055) rather than 
to the twenty-eighth to thirtieth setiger as in L. cirrata (Séderstrém, 
1920). The gills on the second setiger are half as long, and on the third 
setiger about as long as the notopodial postsetal lamellae. The holo- 
type of L. zaponicus has been collected off Japan at Albatross station 
3771, not 5771 as stated by Moore (1907). 
Monro (1933) has observed gills from the third setiger on a frag- 
ment from the Gulf of Panama identified as L. japonica; the dorsal 
sense organ extended to the twelfth setiger. Therefore, his form seems 
to be a different species.
