738 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 14 



coast of North America it has previously been reported by Hincks from 

 the Queen Charlotte Islands, and by O'Donoghue from the vicinity of 

 Vancouver Island, 



In the Hancock collection specimens are from Puget Sound, Wash- 

 ington, Gulf of California, and the west coast of Lower California. 

 Hancock stations, 650-37, San Francisco Island, Gulf of California, 

 and 1714-49, Magdalena Bay, Lower California. Depth range from 

 17 to 47 fathoms. 



Genus ANGUINELLA van Beneden, 1845 



Zoaria erect, branching irregularly. Zooecia cylindrical, arising from 

 a small adnate proximal base. Zooecia bud directly from other zooecia. 

 Genotype: Anguinella palmata van Beneden, 1844.

 Anguinella palmata, Osburn, 1912:253. 



Zoaria palmate, chitinous, opaque, brown in color, consisting of erect 

 single stalks with zooecia branching irregularly to all sides. The zoarial 

 length of the specimens in the Hancock collection ranges from 2.0 to 

 3.1 cm. The zooecia are cylindrical, elongate, rounded distally, the 

 aperture terminal. The cuticle is characteristically covered with a fine 

 coat of silt, rendering examination of the polypide difficult even under 

 optimum conditions of fixation and preservation. The zooecia bud directly 

 from the sides of older mature zooecia. The polypides of the zooecia in 

 the older basal and axial portions of the zoaria are suppressed, and these 

 zooecia serve as support for the younger lateral and distal zooecia that 

 are functional. 



No difference could be detected in the morphology of the Pacific speci- 

 mens when compared with the Atlantic specimens collected at Beaufort, 

 North Carolina, by R. C. Osburn, or those collected at New River, 

 North Carolina, by A. S. Pearse. This is believed to be the first record 

 of this genus and species from the Pacific Coast of North America. 

 According to Hincks, 1880:540, it is moderately abundant in the waters 

 about the British Isles and off the coast of Belgium and France. 



Hancock Stations: 277-34, Isabel Island, Mexico; 447-35, Panama 

 City, Panama; 847-38, off Zorritos Light, Peru; 1449-42, Newport 

 Harbor, and 2020-51, Seal Beach, southern California. Depth range, 

 intertidal zone to 25 fathoms.
