342 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 10 



Distribution. — S. vulgaris is known to occur from New England, 

 south to Georgia; its bathymetric range includes intertidal to several 

 fathoms. It is usually attached to dead shell fragments, or stones. 



Sabellaria vulgaris beaufortensis, new subspecies 

 Plate 32, Figs. 45-47 



Collection. — Near Beaufort, North Carolina, dredged outside inlet, 

 in about 10 fms (several, with tube mass on shell surfaces). 



Small tube masses, removed from the surfaces of dead shells, con- 

 tained several specimens of a Sabellaria, that approach S. vulgaris in some 

 respects, but differ as indicated below. The largest measure only 7 to 10 

 mm long. The opercular paleae are pale yellow; the opercular stalk is 

 pale, with irregularly scattered black spots. Outer opercular paleae num- 

 ber about 22 pairs; they terminate distally in 5 serrations, in addition to 

 the median, longer spike (pi. 32, fig. 45). Median paleae are all of one 

 kind, sharply recurved at their distal end, and more or less strongly trans- 

 versely lined (pi. 32, fig. 46). Inner paleae are distally pointed, trans- 

 versely lined (pi. 32, fig. 47). They differ most significantly from those 

 of S. vulgaris in those of the middle series, since they are strongly re- 

 curved, and the distal ends of the outer paleae have few serrations. 



Holotype.—ARY no. 57. 



Type locality. — Beaufort, North Carolina. 



Distribution. — North Carolina, in about 10 fms.

Grube, 1870, p. 69; Augener, 1934, pp. 151-153, fig. 31. 



Collections. — Beaufort, North Carolina, in the sound, from red 

 sponge (several) ; 832-38 (1). 



Other ?naterial examined. — At the U.S. Nat. Mus., from Beaufort, 

 North Carolina, collected by E. A. Andrews, shore (3). 



This species is characterized in having the middle opercular paleae of 

 2 kinds, including a long (pi. 33, fig. 62) and a short (pi. 33, fig. 63), 

 alternating with one another ; the shorter ones are cuspidate on their inner 

 side. Outer paleae are broad, with elongate, serrate edge at the distal 

 end (pi. 33, fig. 56). Inner paleae are distally entire (pi. 33, fig. 55), 

 intermediate in length between the long and short ones of the middle row. 



The opercular stalk (preserved) is marked with black, longitudinal 

 stripes on the dorsal sides and more or less diffuse black pigment at the 

 sides of the oral tentacles. Outer opercular paleae number about 24 on a
