from the front (fig 6c). The posterior end of the prostomium is obtuse. 
Palps have been lost. There is a very small gill on the first setiger. 
In a well-developed parapodium (fig. 6d), the notopodial and neuro- 
podial postsetal lamellae are present as usual. Also, there is a fairly 
large neuropodial presetal lamella and an interramal papilla. The 
gills are partially fused with the notopodial lamellae. Near the pos-

Paraspio cirrifera, new species: b, dorsal view of anterior end; c, frontal view of anterior 
end (setae of the first setiger are shown on the animal’s right side, setae of the second 
setiger on the left side); d, anterior view of parapodium of 10th setiger (light broken 
lines indicate setae); ¢, hook from 25th parapodium; f, anal cirrus. Trochochaeta multi-

terior end of the animals, the lamellae are reduced, and the gills are 
long and straplike. In the tenth parapodium, a dorsal extension of 
the gill reaches forward, toward the origin of a most characteristic 
notopodial presetal cirrus, which is fairly round in cross-section. This 
cirrus is present at least through the twenty-fifth setiger but visible 
only in well-preserved material without dissection. 
There are notopodial and neuropodial setae in the first setiger. 
The number of neurosetae is about 20. Apart from the wings, the 
setae appear dotted rather than striated. Tridentate neuropodial hooks
