510 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL.10 



those in Loandalia (pi. 63, fig. 3) lacking dorsal cirrus and provided with 

 a distal ventral cirrus. Notopodia are bluntly conical, with heavy single 

 acicula and slender, inconspicuous capillary setae. Neurosetae are also 

 simple, with a smooth shaft and a distal region provided with transverse 

 series of teeth. The posterior end remains unknown. There are no 

 branchiae in so far as known. 



Talehsapia differs from Loandalia, with which it probably has its 

 nearest affinities in the following characters: (1) the prostomium is coni- 

 cal, without appendages instead of having paired palpi and (2) the pro- 

 boscis is provided with jaw pieces instead of lacking them. 



Genus GABIRA Webster, 1879 

 Type C. incerta Webster 



This genus is known for a single species, C. incerta Webster (1879, 

 p. 267) dredged from Virginia, from loosely compacted sandstone. The 

 prostomium is bluntly rounded in front but the lateral margins are said 

 to be prolonged as membranous expansions projecting in front of the 

 head and these expansions are covered with minute papillae. The pros- 

 tomium is provided, dorsally, with a pair of minute, simple antennae but 

 there are no palpi. TBe peristomium has 2 pairs of small, tentacular 

 cirri on each side; it is sharply separated from the first setigerous seg- 

 ment by a deep lateral constriction. 



In the original and only known account, notopodia and neuropodia 

 were probably confounded. At any rate, the dorsal ramus was said to 

 have a small dorsal cirrus and 2 to 4 delicate, capillary setae. The ven- 

 tral ramus was described as a small papilla from which a strong, hooked 

 seta emerges. The first 5 setigerous segments were said to consist of 

 only dorsal rami. The posterior end was not seen. If notopodia ana 

 neuropodia were confused, the notopodia would be small, papillar, with 

 strong recurved hooks, as typical of species of the genus Ancistrosyllis. 

 Neuropodia would then be the larger, provided with long, pointed setae. 



As known today, Cabira differs from other pilargiids most sharply in 

 that the prostomium is said to have paired antennae but lacks palpi. 

 Fauvel (1920, p. 206) has suggested that Cabira incerta is perhaps based 

 on a species of Ancistrosyllis in which the median antenna was lost. The 

 original account is much too faulty and incomplete to merit much con- 

 sideration. The holotype is not known to exist. The name is perhaps 

 best dropped from the list.
