developing larva. The avicularium attached near the base of the zooecium 

 easily separates it from B. longirostrata, which also has an incomplete but 

 somewhat larger ovicell.

The slender, elongate avicularia, at least half as long as a zooecium, 

 and the incomplete ovicell which is shaped like an overturned bowl, 

 readily distinguish this species from other west coast Bugulas. Robertson 

 recorded it from only one locality, "off La Jolla (California) at a depth 

 of 125 fathoms," and O'Donoghue from Cape Ebenshaw, British Co- 

 lumbia. 



The writer collected it on the piles of the Scripps Laboratory wharf 

 at La Jolla, California. The known range of the species is from British 

 Columbia to the Galapagos Islands at the equator, and from the shore 

 to a depth of 125 fms. Judging by the records it would appear to occur 

 regularly at greater depths than our other Bugulas. 



Hancock Stations: 66-33, Tagus Cove, Albemarle Island, 2 to 20 

 fms, and 795-38, Sulivan Bay, James Island, 36 to 60 fms, Galapagos; 

 651-37, east of San Francisco Island, Gulf of California, 60 fms; 1259- 

 41, south of Dewey Channel, Mexico, 49 fms; 1150-40, 1365-41 and 

 1407-41, Santa Catalina Island, southern California, at 21 to 116 fms.

The zoarium is in the form of spiral whorls as much as 50 mm high, 

 similar to B. turbinata Alder of the west European coast and B. turrita 

 (Desor) of the western Atlantic. The globular ovicell, attached at the 

 middle of the distal end of the zooecium ; the presence of three spines 

 and the attachment of the avicularia at the middle of the zooecial wall 

 easily separate it from other Pacific coast species. In addition, two sizes
