 cirri. Proboscis short, cylindrical, with few scattered papillae. 

 With conspicuous rust-colored glandular areas in anterior part of 

 notopodial lobe (beginning on setiger 4) and ventrally near bases 

 of parapodia (fig. 3d). Integument with numerous scattered short 

 papillae.

Ancistrosyllis breviceps Hartman, 1963, p. 13, fig. 1, a-d. 



Material examined: Holotype of Ancistrosyllis breviceps, Santa 

 Monica Canyon, 386 fms., Sta. 7517, loan from Olga Hartman (AHF). 



Description: Body depressed, parapodia longer than body width. 

 Prostomium small, with large palpophores and small palpostyles 

 (visible ventrally) ; antennae very short, not extending beyond palps. 

 Tentacular segment mth 2 pairs of subequal tentacular cirri, longer 

 than antennae. Dorsal cirri of first setiger slightly longer than 

 following. Notopodia low, with slender notoacicula and prominent 

 emergent hooked setae beginning about setiger 13 (possibly irregular, 

 not emergent at first) ; dorsal cirri short, subulate. Neuropodia long, 

 subcorneal, \vith neuroacicula and simple neurosetae. Neurosetae 

 variable in length, with tips slightly hooked (according to Hartman, all 

 neurosetae taper to fine tips) . Ventral cirri short, subulate, begin on 

 first setiger. Proboscis? Pygidium? Integument minutely papil- 

 lated, especially dorsaUy. 



Distribution: Southern CaHfornia. In 191-533 fms.
