NO. 1 HARTMAN : GONIADIDAE, GLYCERIDAE, NEPHTYIDAE 103 



A collection reported as N. malmgreni Treadwell (1914, p. 192) 

 from Ballast Point, has been reexamined and is referred to this species. 

 Berkeley (1945, p. 327) raised this from subspecific to specific rank. 



Distribution. — N. ferruginea is known from British Columbia, 

 Canada south to Peru in depths of 10 to 230 fms; it is taken from soft 

 mud or clay substrata. 



Nephtys californiensis Hartman 



Hartman, 1938, pp. 150-151, fig. 64; Hartman, 1940, p. 240; Hartman, 

 1944c, p. 251. 



Collections not previously reported.— 1459-42 (2); 1597-47 (1); 

 1620-48 (1); 1759-49 (1); 1882-49 (1); 1886-49 (1); Dillon Beach 

 and Bodega Head, Marin County, California (about 25) ; outer beaches 

 at San Francisco, California (2). 



Most of these specimens show the characteristic "spread eagle" 

 pattern of the prostomium (Hartman, 1938, fig. 64) but there is some 

 variation in the first occurrence of interramal cirri. In some (1597-47 

 and 1759-49) it is first present from segment 3, in others (1620-48, 

 1882-49 and 1886-49) it is first present from segment 4. The specimen 

 from 1587-47 is further different for having, in addition to the pro- 

 stomial pattern, a broad transverse dark stripe on some posterior seg- 

 ments. 



Distribution. — This occupies shifting intertidal sands of central 

 California, south to the Gulf of Mexico ; it seldom occurs to 30 fms. In 

 its southern range it seems to intergrade (or hybridize?) with N. 

 caecoides, above, so that individuals of the 2 species are sometimes not 

 clearly distinguishable. 



Nephtys picta Ehlers 



Nephthys picta Ehlers, 1868, pp. 632-635, pi. 23, fig. 9, 35; Hartman, 

 1938, p. 9; Hartman, 1945, pp. 22-23. 

 Collections. — Cape Lookout, North Carolina (4) ; Grand Isle, 

 Louisiana (2, gift from Dr. E. H. Behre) ; Beaufort, North Carolina 



(6). 



Total length approaches 85 to 150-200 mm. The anterior dorsum is 

 marked with dark transverse bars segmentally arranged. The prostomium 

 is approximately pentagonal seen from above; its anterior margin is 

 straight and broadest, with a thin, spatulate edge ; the anterior or frontal 

 antennae are prolongations of the anterior lateral edges. The posterior
