12 ALLAN HANCOCK ATLANTIC EXPEDITION REPORT 



thicker, spinous aristate setae (pi. 1, fig. 6), 4 to 6 heavy, yellow aristate 

 setae (pi. 1, fig. 5) from which the terminal portion has dropped ofif in 

 nearly all instances, in the middle portion of the fascicle, and geniculate 

 spinous setae (pi. 1, fig. 7) in the inferior part of the fascicle. Bushy- 

 topped or brushlike setae are altogether lacking. 



Spinning glands are first present from the ninth setiger, continued to 

 the end of the piece. 



E. oculata differs from known species of Eupanthalis most notably in 

 the possession of its enormous anterior eyes and the character of its supe- 

 rior neuropodial setae. 



Holotype.—AHY no. 72. 



Type locality. — South of Cape la Vela, Colombia, in 21-22 fms (A 

 14-39). 



Distribution. — Colombia, Atlantic side. 



Panthalis, sp. 



Collection. — A 4-39 (an anterior fragment). 



A single anterior end of 37 segments, measures 24 mm long. The 

 dorsal surface is marked with reddish brown in the form of broad, trans- 

 verse bars across the segments ; a large part of the elytral surface is covered 

 with a similar pigment. Palpi, peristomial cirri, and the first 2 pairs of 

 elytra are marked with many fine dark specks, ranged in transverse lines 

 on the palpi. Ommatophores are elongate oval, set off from the prostomi- 

 um by constricted bases, with conspicuous, lenticulated eyes in their distal 

 half. The smaller, sessile eyes are at the anterior third of the prostomium, 

 in front of the insertion of the median antenna. The latter has its origin 

 at the midlength of the prostomium ; its style extends distally to the ends 

 of ommatophores. The paired antennae are inserted ventrally, posterior to 

 the base of the ommatophores. 



The first elytra are small, oval, the second a little larger; both are 

 pale, with small dark specks. Farther back they increase in size but con- 

 tinue circular to oval, with entire smooth margin and have large, rust- 

 colored blotches instead of fine black specks. The elytrophore is far to the 

 side, near the lateral edge. 



The first segment is reduced to a pair of long, forward-projecting, 

 parapodial lobes with thick, tapering, subequal dorsal and ventral cirri, 

 each speckled with dark pigment and provided with small dorsal and ven- 

 tral tufts of a few fine, pointed setae. The second parapodia have the first 

 pair of elytra, a ventral cirrus resembling that of the first, and slender, 

 pointed setae in both notopodia and neuropodia, but spinous, geniculate 

 setae in the inferior part of the neuropodial fascicle. From the third, setae
