NO. 1 hartaian: polychaetous annelids 49 



Neuropodia have long, pointed acicular lobes and shorter, rounded 

 postsetal lobes. The long, triangular acicular lobe extends laterally al- 

 most one third as far as the longer neuropodial setae (pi. 9, fig. 112). 

 Ventral cirrus is slender, cirriform, inserted on the proximal third of 

 the ventral face of the parapodium and hardly extends to the base of 

 the inferiormost setae. 



Notopodial setae are of one kind, slender, tapering, rod-like, with a 

 row of minute teeth along one edge (pi. 9, fig. 114). Neuropodial setae 

 aie of two kinds, (1) slenderer, supraacicular, with few in a fascicle, 

 and (2) heavier, with a long stem and a distal expanded portion pro- 

 vided with some obscure teeth on the cutting edge (pi. 9, fig. 115) and 

 bifid tip (pi. 9, fig. 113). In a few anterior segments a small superior 

 fascicle includes setae that are smaller, bent, the serrations not distinct. 



A smaller, perhaps juvenile, posteriorly nearly complete specimen 

 (532-36) consists of 34 segments, is about 10 mm long and 1.2 mm 

 wide without parapodia. It resembles the larger piece, but is paler and 

 the eyes are not lenticulated. Both specimens have the proboscis pro- 

 truded a short distance. 



Only 2 species of this small genus have heretofore been described. 

 H. magna Moore (1905, p. 541) was dredged in 95-110 fms. from the 

 Gulf of Georgia and southeastern Alaska, and later reported from 

 British Columbia (Berkeley, 1923, p. 214). H. magna differs from H. 

 veleronis in that it lacks the long parapodial lappets, the setae are more 

 distinctly serrated, the prostomium is different (see Moore, 1905, pi. 

 35, figs. 24-29). 



Hololepida australis Monro (1936, p. 93) was described from the 

 vicinity of the Falkland Islands in depths of 135-267 meters. It differs 

 from H. veleronis in having a different kind of nuchal hood, the setae 

 are otherwise, and parapodial structures differ. H. australis measures 90 

 mm for 38 segments, H. veleronis is only 14 mm for 20 segments. 



Hololepida veleronis has smooth setae and soft white scales that re- 

 call those of commensal polynoids. No notes were made as to its color in 

 life, or its association, if any. 



It is named for the motor cruiser, Velero III, during a cruise on 

 which these collections were made.
