Harmothoe (Lagisca) yokohamiensis Mcintosh. 



Lagisca yokohamiensis Mcintosh, Challenger Reports, Zoology, Vol. XII, 

 pp. 89, 90, PI. XIA, figs. 12 and 13. 



This species lacks the large soft papillae that adorn the elytra of the 

 two preceding. The horny papilla? are small, conical or truncate and 

 are uniformly distributed over the entire exposed portion of the elytra. 

 Marginal cilia are moderately long and have slightly bulbous tips and 

 a few longer cilia are borne on the surface near the posterior margin. 



Notopodial setae are rather stout, the largest about three times the 

 diameter of the neuropodials and their smooth tips (PI. XXXI, fig. B) 

 are much longer than in the preceding species, the rows of spines very 

 numerous and the longest nearly encircling the seta. The extent to 

 which they bend over the dorsum and protect the elytra is noteworthy 

 and calls to mind the condition in Gattyana. Neuropodials (PI. XXXI, 

 fig. A) also have much longer tips and only twenty to thirty pairs of 

 pectinated plates and the rather prominent accessory tooth is present 

 on all but the ventralmost rows. Notocirri are long and very slender 

 with the subterminal enlargement scarcely visible and the terminal 

 filament unusually long and bear a moderate number of clavate cilia 

 much longer than those on the tentacles. 



Several have the proboscis protruded. In one 28 mm. long it is 

 4.6 mm. long and 2.5 mm. at the orifice. It is clavate, the distal end 

 nearly circular, the mouth rather small and lozenge-shaped; orifical 

 papilla? nine above and nine below. Jaws pale brown, the fangs 

 compressed, prominently outstanding like a parrot's beak and the 

 knife-like cutting plates directed more antero-posteriorly than trans- 

 versely. Complete examples have from forty-four to forty-six seg- 

 ments. 



Color above dark or usually pale brown with or without narrow 

 transverse white lines, below nearly colorless. Elytra colorless or the 

 posterior part marked with brown usually in three large blotches. 

 Ova occur in only one specimen from an unknown station. 



This may be the Hawaiian species referred to H. haliaeta Mcintosh 

 by Treadwell. These specimens agree very closely with Mcintosh's
