NO. 3 HARTMAN : POLYCHAETOUS ANNELIDS 351 



Collections from Chile and Peru compare favorably with the type 

 from Hawaii. An anterior end, in right lateral view, is shown in pi. 36, 

 fig. 80. Outer (pi. 36, fig. 81), middle (pi. 36, fig. 83), and inner (pi. 

 36, fig. 82) paleae are typical. 



Ehlers (1901, pp. 199-203, pis. 23, 24) described as P. virgini some 

 specimens which are undoubtedly representatives of P. moerchi. The 

 description, moreover, indicates that more than one species is involved, 

 as may be seen by comparing the figures on his plate 23 (cf. figs. 3, 4, as 

 against figs. 5, 6). The outer opercular paleae (Ehlers' pi. 23, fig. 11) 

 are seemingly those of P. moerchi, and obviously not P. virgini (below), 

 since they have a terminal flange. Ehlers says, in part, of these paleae, — 

 "Die messingelben ausseren Paleen tragen auf dem in der Haut stecken- 

 den diinnen und schlanken Stiel eine im Winkel dazu nach aussen ge- 

 bogene Endplatte, die etwa dreimal breiter als lang ist [This should 

 probably read longer than broad], wie eine Wurfschaufel gehohlt, mit 

 parallelen Seitenrandern, am Endrande mit einigen Seitenzahnen ver- 

 sehen, die ein schmaleres vorspringendes rechteckiges Endblatt umgeben, 

 das am freien Rande sageartig gezahnelt ist." In P. virgini there is no 

 terminal plate (pi. 35, fig. 77) such as is present in P. moerchi (pi. 35, 

 fig. 76). 



Distribution. — P. moerchi ranges in tropical and subtropical eastern 

 Pacific, from Peru to Chile, west to Hawaii. It is intertidal to 15 fms.

Material examined. — ^Type specimen, Swedish State Museum (no. 

 923), from southern Chile. 



The following comments are based on the type specimen, from south- 

 ern Chile. Outer opercular paleae have only 2 main teeth along their 

 outer, distal margin, without dentations or a flange between them (pi. 35, 

 fig. 77). The concave edge between these 2 teeth is thin, membranous, 

 with no indication that there ever was an attached flange or other struc- 

 ture. The upper surface is weakly striated but not at all scabrous as in 

 P. moerchi (above). Middle opercular paleae (pi. 35, fig. 78) are com- 

 paratively smooth, much finer than comparable ones in P. moerchi. The 

 opercular cone, seen from the top, is subcircular, but the middle paleal
