126 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 25 



Numerous individuals of a small capitellid, about the size of Medio- 

 mastus calif orniensis Hartman, and frequently in the same samples, 

 differ from the latter in that the prostomium is acutely pointed, and 

 directed obliquely downward. A pair of black eyespots is visible near its 

 posterior margin. The everted proboscis is sacklike and covered with 

 coarse papillae. The first segment is achaetous, with the ring nearly as 

 long as the next, or first, setigerous segment. The first parapodia are 

 uniramous and represented by notopodia only. The setigerous formula 

 of the thorax may be expressed as follows: 9 notopodia with setae, one 

 mixed and this followed by hooks ; 7 neuropodia with setae, 2 with hooks, 

 and this followed by hooks. Separation between thorax and abdomen 

 is not sharp. It is thus possible that the thorax consists of 10 setigerous 

 segments because the tenth notopodium has both setae and hooks. 



Representatives of this form are seemingly limited to very shallow 

 sandy bottoms of southern California.

Fauvel, 1927, p. 182-183, fig. 63. 



Collection. VELERO IV Sta. 5557. 3.4 mi from Pt. Conception 

 light, California, in 12 fms, shaley rock. 



Two large anterior ends agree with the account given by Fauvel 

 (1927, p. 182). The cephalic plaque resembles that of Asychis spp. 

 because the nuchal ridges are inconspicuous and limited to a short an- 

 terior part of the plaque. The collar on the fourth segment is con- 

 spicuous and followed by lesser collars on the next 3 segments. The 

 single heavy spines in neuropodia of the first 3 segments agree with 

 those described from western Europe. 



This species is more widely known from western Europe.

Collection. VELERO IV Sta. 5538, 3.35 mi from Hyperion stack

This species lacks segmental collars. The first setigerous segment has 

 2 large spines in a neuropodium, the second has 3 such spines and the
