well, 1921), the eastern tropical and subtropical Pacific, from California 

 south to western Mexico and west to the Galapagos Islands. Its bathy- 

 metric range extends from the intertidal zone to 55 fms.

The prostomial antennae are short, smooth or irregularly ringed, but 

 not at all moniliform. The peristomium is prolonged, about as long as 

 broad ; the shorter portion bearing the cirri is set of? dorsally by a trans- 

 verse groove. Peristomial cirri are cirriform, about half as long as the 

 peristomium. The peristomium is marked by longitudinally disposed, 

 shallow, closely spaced wrinkles. 



The maxillary formula is about as follows: maxillae I are falcate, 

 II with 4-5 teeth left and 3-4 right. III with 4-5 teeth left and 6-8 

 right, IV with 3-7 teeth left, none right. There is considerable variation 

 in the number of teeth on maxillae II to IV, as typical in most species of 

 this genus, but the disposition of parts is about the same in most species. 



Acicula are deep amber, distally hammer shaped (pi. 6, fig. 124). 

 Subacicular hooks are horny brown, distally bidentate, and strongly 

 beaked (pi. 6, figs. 123, 125). Composite setae are distally bidentate and 

 hooded (pi. 6, fig. 126). 



The lengthy synonymy of this species has been discussed by various 

 authors (Augener, 1925, p. 9; Monro, 1933, pp. 65-66; 1936, vol. 27, 

 p. 248). 



Distribution. — Eastern and western tropical America, Bermuda. Us- 

 ually intertidal ; rarely to depths of 21 fms.
