40 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 7 



Lepidonotus hedleyi Benham 



Lepidonotus hedleyi Benham, 1915, pp. 181-183, pi. 38, figs. 1-7; 

 Fauvel, 1932, p. 14; Okuda, 1937, pp. 267-268, fig. 8. 



Collection. — 549-36. One individual. 



The dorsum of anterior segments is traversed by a broad band of 

 brown pigment, segmentally arranged. Prostomial prolongations, median 

 ceratophore including the style, and the palpi, have a similar dark color. 



The prostomium is a little wider than long, a median sulcus sepa- 

 rates the lobes. The 4 eyes are black, conspicuous, the anterior pair at 

 the broadest part of the prostomium. Elytral margin is entire; its sur- 

 face is provided with widely separated blunt chitinous spines, and pig- 

 mented patches that are interspersed with clear, mesh-like areas. The 

 elytra extend laterally about as far as the neuropodia but they do not 

 nearly cover the neuropodial setae. 



Notopodial setae are transversely serrated ; most of them are longer, 

 distally pointed, but a few in the superior part of the fascicle are short, 

 slightly arcuate. The notopodial setae of the first parapodium (segment 

 2) are all of the pointed kind. Neuropodial setae are dark yellow; typi- 

 cally all are bifid, with a rather short, serrated area. In the first para- 

 podium all of the neuropodial setae are long, pointed, without a sub- 

 terminal tooth. 



Distribution. — Australia; Indian Ocean; South Sea Islands; Gulf 

 of California, east of Angel de la Guardia Island. Intertidal to 40 fms. 



Lepidonotus versicolor Ehlers 



Plate 5, Figs. 56, 59-61 



Lepidonotus versicolor Ehlers, 1901, pp. 50-52, pi. 3, figs. 1-9 (not 

 Augener, 1922, pp. 173-174, fig. 1). 



Collections. — 529-36, 728-37. 2 specimens. 



Length to 25 mm; width 9 mm with, 7 mm without parapodia. 

 Elytra firmly attached, covering the dorsum but leaving the neuropodial 

 setae exposed. In 728-37, only the first 2 pairs of elytra have conspicu- 

 ous surface tubercles (pi. 5, fig. 56). In 529-36, the first 7 pairs of elytra 

 are thus covered. Their margin is entire, or the first few pairs of elytra 

 have a row of sparse, short, inconspicuous fringes (pi. 5, fig, 56). The 

 first few pairs of elytra have numerous, pale yellow subglobular tu-
