length but continues to exceed the presetal one in length. A seventeenth 

 parapodium has the proportions shown in pi. 12, fig. 273; it is provided 

 with 2 dark brown acicula, 4 limbate setae (omitted from the figure), 

 and 2 simple hooded hooks. Parapodia continue small through the oviger- 

 ous region, or to the ends of the pieces in the collections, but none is pos- 

 teriorly complete. A single, limbate seta may continue through about the 

 thirty-fourth parapodium; thereafter only 2 or 3 simple hooks, accom- 

 panied by 2 dark brown acicula, are present; this arrangement is con- 

 tinued through about 84 segments. 



Composite hooded hooks (pi. 13, fig. 275) are present from the first 

 setiger through 15 or 16 segments; they are accompanied by broadly bi- 

 limbate setae (pi. 13, fig. 276). Farther back the composite hooks are re- 

 placed by simple hooded hooks (pi. 13, fig. 277). Acicula appear dark 

 under low, dusky brown under high, magnification. Setae and hooks are 

 pale. 



The proboscidial armature is dark. Mandibles are clear except for 

 light brown areas marking the scars of muscle attachment; they have 

 slender basal ends and a dentate cutting edge distally (pi. 12, fig. 271). 

 Maxillae have long, laterally incised carriers, broad falcate forceps, and 

 maxillaiy plates that are clearly toothed on their cutting edges; maxillae 

 II have 4 teeth each; maxillae III and IV have each a sharp tooth on 

 either side; the fourth plates are attached to a large, flat, brown plate 

 (pi. 12, fig. 270). 



The large, reddish eggs are more or less spherical, number 4 to 8 in 

 a segment, and measure not quite 0.2 mm in diameter. 



Holotype. — AHF no. 52. 



Type locality. — South side of San Nicolas Island, California, in 24- 

 34fms (coll. 1205-40). 



Distribution. — Southern California and off Todos Santos Island, 

 Mexico, in 24-57 fms.

Collection.— A 3S-39 (1). 



A single collection has revealed this unusual species, which has not 

 been reported on since first described by Kinberg (1865, p. 570) from 

 Rio de Janeiro, Brazil, except for a change of name by Grube (synonymy 

 above). The original brief description was inadequate to permit identi-
