34 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 15 



The first parapodium is small ; it has 3 long, triangular lobes includ- 

 ing a dorsal cirrus with a boss at the base, a postsetal lobe and a ventral 

 cirrus. On the second parapodium the presetal lobe is much the longest 

 but the 3 lobes are similar in other respects. Farther back the neuro- 

 podium increases in size. At the sixth parapodium the presetal lobe 

 acquires a slender, inferior spur, the beginning of the bifurcated pre- 

 setal lobe. This branch comes to be gradually larger so that by the 

 fourteenth parapodium the 2 presetal lobes are about equal. A single 

 small postsetal lobe is first seen at the sixth parapodium; it gradually 

 increases in size so as to be clearly visible at the twelfth ; it remains far 

 shorter than the presetal lobes but is similar in other respects. The 

 ventral cirrus is the longest and broadest lobe in most anterior seg- 

 ments; it is dark brown except for the ivory tip. In biramous parapodia 

 the notopodium consists of 2 broadly triangular lobes that are dark 

 brown, with the pale yellow, bluntly tapered few (to 3) acicular setae 

 projecting from them. The neuropodium comes to be broad, with a 

 large, foliaceous, acutely pointed postsetal lobe and deeply bifurcated 

 presetal lobe. The ventral cirrus remains large, brown, but is not con- 

 spicuous as in front, since the neurosetal lobes surpass them. Notosetae 

 are bluntly acicular, few, one to 3 in a bundle ; neurosetae are composite 

 spinigers, in fanshaped fascicles. 



Distribution. — G. teres is known only from Montego Bay, Jamaica, 

 British West Indies.

Length of 280 segments is about 230 mm. Anterior uniramous 

 segments number 88-90, with 2 or 3 transitional segments in which 

 the notopodium is abruptly developed. The prostomium has a large 

 basal ring and 6 shorter distal ones, with 4 antennae at the end. Uni- 

 ramous parapodia have 2 long, digitate lobes, a much shorter postsetal 

 lobe and dorsal and ventral cirri both prolonged, the ventral one exceed- 

 ing all other parapodial lobes in length and width. Biramous parapodia 

 have short lobes throughout. Their notopodia have dorsal cirrus and 

 setal lobe about equally long, acuminate at the tip but broad at the 

 base, and 3 coarse, acicular short spines in a fascicle. Neuropodia have 

 broadly bifid presetal lobes, a single, equally long postsetal lobe and a 

 much shorter ventral cirrus. Their separate lobes are broad at the base 

 and taper to acute short tips. Neurosetae occur in fanshaped fascicles; 

 they are entirely composite spinigers.
