NO. 1 HARTMAN : POLYCHAETOUS ANNELIDS 185 



The Lysaretidae have been recorded from the Western Hemisphere 

 through 4 genera and 4 species, but one of them (Oenone brevimaxillata 

 Treadwell) is beh'eved to be synonymous with another {Lysarete bra- 

 siliensis Kinberg), and another {Enonella bicarinata Stimpson) is ques- 

 tionable. ( 1 ) Aglaurides fulgida Savigny is known throughout the West 

 Indian region and is further reported below. (2) Lysarete brasiliensis 

 Kinberg, originally described from Brazil, was later redescribed and re- 

 corded from Florida (Ehlers, 1887, pp. 107-108, pi. 33, figs. 1-8). I have 

 collected the same species from Lemon Bay, Florida, from masses of de- 

 bris in the intertidal zone. (3) Oenone brevimaxillata Treadwell (1931, 

 pp. 1-3, figs. 4-9) from Mexico (whether east or west coast is not known) 

 is probably the same as Lysarete brasiliensis. The 3 prostomial antennae 

 are about as long as those of the latter, but no mention is made of eye- 

 spots. The first 2 segments are shown apodous, but the same region is 

 said to be uniannulate ventrally; acicula are black, as in L. brasifiensis ; 

 the maxillary plates are similarly dentate, but the division between max- 

 illary plates and carriers appears to be misplaced in the more recent de- 

 scription ; the free ends of the mandibles are shown much shorter in O. 

 brevimaxillata than is typical for L. brasiliensis, but this may be due to 

 foreshortening. (4) Enonella bicarinata Stimpson (1853, p. 34, fig. 25) 

 from the Bay of Fundy, is too incompletely known to identify beyond 

 family. Only 2 species, therefore, are definitely known to be present from 

 the Western Hemisphere. One of them (below) has been collected 

 through numerous examples by the Velero III, the other has been col- 

 lected by the author.

This species has already been made well known through numerous 

 excellent accounts (see synonj'^my above). Considerable discussion has 

 evolved about the form and structure of the maxillae. In some individuals
