40 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL.15 



presumed to be absent. Proboscidial organs are of 2 kinds; very numer- 

 ous, bluntly conical ones are irregularly dispersed over the proboscidial 

 surface, and somewhat larger ones with compressed bifid summits occur 

 more sparingly and are confined to the muscular ridge. Both have the 

 cuticle thickened and a single sensory pore just behind the apex. Macro- 

 gnaths are black, somewhat dorsal, each with 4 clawlike teeth, diminish- 

 ing in size dorsally. Micrognaths number 13 in the dorsal and 18 in the 

 ventral arc. 



Distribution. — O. distorta is known only from Suruga Bay, Japan 

 in 35-65 fms. 



Ophioglycera foliacea (Moore), new combination 



Goniada (Leonnatus) foliacea Moore, 1903, pp. 457-460, pi. 26, figs. 

 75-76. 



This species agrees with the genotype of Ophioglycera in lacking 

 proboscidial chevrons and in having similar parapodial parts. The pro- 

 stomium has only 4 rings, including a basal one that nearly equals the 3 

 distal ones together; they terminate in 4 antennae. A specimen nearly 

 complete measures 98 mm long for 160 segments. The parapodial change 

 from uniramous to biramous is at about segment 35, with only a few 

 segments transitional. Notosetae are slender, simple and distally pointed. 

 Neurosetae are composite spinigers, arranged in fanshaped fascicles. On 

 the proboscis the macrognaths have 2 larger and 2 or 3 smaller ciawlike 

 teeth. Micrognaths number 14 or 15 in a shorter dorsal arc and 28 to 

 30 in a longer ventral arc. 



This species differs from others in the genus in having a short an- 

 terior region (about 35 segments) and few prostomial annuli. 



Distribution. — O. foliacea is known only off Japan in 62-190 fms. 



Ophioglycera longicirrata (Arwidsson), new combination 



Goniada ? longicirrata Arwidsson, 1899, pp. 47-48. 



This species lacks proboscidial chevrons, hence is referred to Ophio- 

 glycera. A specimen measuring 34 mm long consists of 165 segments. 

 Dorsal and ventral cirri in the anterior region are conspicuously longer 

 than is typical for other species of the family GONIADIDAE. The 

 parapodial change from uniramous to biramous occurs at segment 58. 

 Notopodia have about 3 large, acicular spines ; neuropodia have com- 

 posite spinigers in fanshaped fascicles. Macrognaths are said to have 

 only 2 teeth; micrognaths number only 6 (probably) in the ventral 

 series and are lacking from a dorsal one. The prostomium was not 

 described.
