334 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 15 



The body measures about 6 mm long, 0.5 mm wide and consists of 

 about 73 segments. The prostomium has a pair of eyespots. The first 

 segment is a smooth ring. Branchiae are present from the fifth setigerous 

 segment and were originally presumed to be present on all segments (as 

 in Orbiniidae), later corrected but not clarified (Augener, 1923, p. 72- 

 75). Monro (1930, p. 150) questionably referred the species to his 

 Paraonis (Paraonides) gracilis, but the large number of branchiae con- 

 tradicts this view. Furthermore, posterior neuropodia were originally 

 shown with projecting acicular spines (Augener, 1914, text-fig. 3), re- 

 calling those of Scoloplos (Leodamas) in the Orbiniidae. 



Augener (1923, pp. 72-75) redescribed the species and recorded a 

 maximum length of 12.5 mm for 35 segments; buccal segment apodous; 

 pygidium with a large midventral and a pair of smaller lateral processes ; 

 branchiae cylindrical and present from eighth setigerous segment. 



Distribution. — This species is recorded from Antarctic regions and 

 southwestern Australia. 



Genus Paraonis (Paraonides) Cerruti, 1909 

 Type Paraonis (Paraonides) neapolitana Cerruti, 1909 



This subgenus differs from Paraonis sensu stricto in that neuropodia 

 have no modified setae. Postbranchial notopodia have setae of char- 

 acteristic form. In the genotype they are distally pointed and limbate 

 (winged). In others there are furcate (lyrate) setae in addition to 

 slender pointed setae.

The genotype, Paraonis {Paraonides) neapolitana Cerruti (1909), 

 is known only from Europe (see Fauvel, 1927a, p. 73).

The individuals examined are very small. A complete one with 70 

 segments measures 7.5 mm long and about 0.16 mm across. Southern 

 (1914), for specimens from Ireland, recorded a length of 12 to 20 mm
