NO. 3 HARTMAN : POLYCHAETOUS ANNELIDS 339 



A considerable number of species from the Western Hemisphere have 



been described as Sabellaria (or one of its synonyms) , but some have been, 



or are herein being, referred to other species or genera, indicated in 



brackets below. They are as follows : 



S. bella Grube. 



S. bellis Hansen (Augener, 1934, pp. 151-153, fig. 31) from Brazil (see 

 key below). 



[5. calif ornica Fewkes, see PhragrnatopomaJ\ 



S. cementarium Moore. 



[5. falcigera Johansson, see S. vulgaris. \ 



S. fissidens Grube (Ehlers, 1901, pp. 196-199) from Chile (see key 

 below). 



[Hermella macropalea Schmarda, see Idanthyrsus and Phragmatopoma.] 



S. nanella Chamberlin (1919, pp. 261-266) from California (see key 

 below). 



[Hermella orbifera Ehlers, see Phragmatopoma.] 



S. pectinata moorei Monro (1933, pp. 1063-1064, fig. 12) from Balboa, 

 Panama. (This comes close to S. bellis, see key below.) 



[Centrocorone spinifera Treadwell, see Phragmatopoma.] 



S. spinulosa Leuckart (Monro, 1933, pp. 1063-1064) from Balboa, Pan- 

 ama. (This differs from typical S. spinulosa in its much smaller size, 

 but was not described in other respects.) 



[5. varians Webster, see S. vulgaris. ] 



{Hermella varians Treadwell, see Lygdamis.] 



[iS. virgini Ehlers, see Phragmatopoma.] 



S. vulgaris Verrill. 



In addition, S. spinulosa alcocki Gravier has been reported (Fauvel, 



1919, pp. 477-478) from French Guiana, but differs from Gravier's 



species in that the paleae of the middle opercular row do not alternate 



long and short, but are all of the same length. S. alcocki has been further 



reported from southern California (Berkeley, 1941, p. 51) ; it may be 



close to, if not identical with, S. bella Grube (below). Two species, S. 



floridensis and S. gracilis, and one subspecies, S. vulgaris beaufortensis, 



are newly described. 



Key to Species of Sabellaria Lamarck 



1. Inner opercular paleae distally serrated (pi. 31, fig. 40) . . . 2 



1. Inner opercular paleae distally simple (pi. 32, fig. 42) . . . 3 



2. Middle opercular paleae short, spoon-shaped (pi. 30, figs. 25, 

 28) S. bellis Hansen and S. moorei Monro^ 



3 The outer, middle, and inner paleae, as originally shown, are as in plate 30, 

 figs. 27-29 for S. bellis, and as in plate 30, figs. 24-26 for S. moorei; the similarities 

 are so striking that it is difficult to separate them.
