SABELLIDES AND SERPULIDES I97 



Tubes thin and flexible ; brown, with a tinge of pink ; joined to 

 each other, covered with exceedingly fine gray sand, to which delicate 

 hydroids are attached. 



This is readily distinguished from the other allied forms by the more 

 numerous branchiEe, with their very long crowded pinnae and irregu- 

 larly arranged brown spots. 



SABELLA ( ?) VANCOUVERI Kinberg. 

 Sade/la vancouveri KitiBKRG, Annulata nova, p. 353, 1866. 



Type locality. — Vancouver Island, British Columbia. 



Nothing corresponding to this species occurs in the present collection. 



It was described by Kinberg (1866) as having a stout body ; 8 or 9? 

 thoracic segments ; 183 branchia; on both sides, 18-23 i^""'- lo^g? with 

 5 purple bands ; setaj limbate, hastate ; uncini ; length of the 36 an- 

 terior segments, 60 mm. 



No mention is made of the form of the branchial lobes, yet the large 

 number of branchiae make it improbable that the species can be a typ- 

 ical Sabella. No species of Eudistylta^ however, has more than 3 

 bands of color on the branchiae, and those of Schizobranchia are not 

 banded. 



Genus Paralaonome nov. 



Type, Laonome japonica Marenzeller. 



The above species was erroneously referred by Marenzeller to the 

 genus LaoJiome of Malmgren (1865) , agreeing with L. kroyeri Malm- 

 gren, the type, only in having a single series of avicular uncini in all 

 the tori ; these differ greatly in form, however, being distinctly pro- 

 longed posteriorly, not truncated as in Malmgren's species. 



The branchial lobes are large, prolonged ventrally, spirally coiled 

 in retraction, as in Sabella^ and bear numerous branchiae arranged 

 in a double series. 



The narrow four-lobed collar differs, also, from the much more con- 

 spicuous two-lobed one on L. kroyeri. 



Paralaonome is therefore proposed for the reception of the Japan- 

 ese species, notwithstanding the fact that Saint-Joseph (1S94) sug- 

 gested that it should be referred to the genus Sabellastarte Savigny 

 (1809), type S. indica Savigny (1809), although it does not appear to 

 agree very closely with the other species placed there. 



Laonome antarctica Kinberg (1866) from the Straits of Magellan 

 may prove to be a related species.
