NO. 1 HARTMAN : POLYCHAETOUS ANNELIDS 91 



setae. By the seventh setiger the hooded hooks are replaced by 2 to 4 com- 

 posite spini'gers (pi. 11, fig. 240) and also bilimbate pointed setae. Pos- 

 terior parapodia are provided w^ith bidentate, subacicular hooks (pi. 11, 

 fig. 244), fine pectinate setae with about 7 or 8 rather w^idely spaced 

 teeth (pi. 11, fig. 245), and bilimbate, simple setae. Subacicular hooks 

 are first present from the thirteenth or fourteenth setiger, replacing the 

 ventral limbate setae. 



The proboscidial armature differs rather sharply from that of the 

 original account. The mandibles are long, slender, united at the distal 

 end for a short distance (pi. 11, fig. 241), and much longer and slenderer 

 than first shown. The maxillae have broadly rounded carriers (pi. 11, 

 fig. 247) ; the forceps are falcate; the other pieces are as follows: on the 

 left side maxilla II has 7 teeth, III has 7 teeth, IV has 6 teeth, V has a 

 single tooth; on the right side, II has 6 teeth, III has 10 teeth, and V 

 has a single tooth. 



The individuals from Pillar Point were taken from sandy beaches; 

 there is no permanent tube. 



Distribution. — False Bay, Puget Sound ; Pillar Point, San Mateo 

 County and Point Loma, California; Thurloe Bay, Lower California; 

 bathymetric range from intertidal to 33 fms. 



Nothria stigmatis paradiopatra, new subspecies 



Collections. — Cypress Point, near Monterey, California (5); 1197- 

 40(1). 



Several specimens from the intertidal zone at Cypress Point, Cali- 

 fornia, agree in all essentials with those from Pillar Point (above) save 

 that they entirely lack branchiae, hence might be referred to the genus 

 Paradiopatra Ehlers (1887) as first defined. Presence or absence of 

 branchiae has been found to vary widely in members of the Onuphidae; 

 it may have less than specific significance. 



The single specimen from collection 1197-40 differs slightly from 

 the others in that its dorsal cirri are proportionately longer, but not 

 nearly so long as those in N. stigmatis cirrata (below). 



Holotype. — AHF no. 41. 



Type locality. — Cypress Point, near Monterey, California, int"' f.idal. 



Distribution. — Central California; intertidal to 10 fms.
