NO. 1 OSBURN : EASTERN PACIFIC BRYOZOA CHEILOSTOMATA 159 



hemispherical cap set close against the distal end of the zooecium. 



Described by Harmer from New Guinea and the Java Sea; recorded 

 by Hastings from Coiba, Panama, and the Galapagos Islands. 



Hancock Stations: 66-33, Tagus Cave, Albemarle Island, Galapagos, 

 10 to 20 fms. Also at Albatross Sta. 5771, San Francisco Bay, CaHfornia, 

 several colonies.

Bugula cucullata Verrin, 1897:188 (preoccupied, Busk, 1867:241). 

 Bugula cucullifera, O.Donoghue, 1923:22; 1926:45. 



The zoarium is erect and the branches little divergent. The zooecia 

 are moderately elongate, narrowed gradually to the proximal end, the 

 distal end more or less transverse; the opesia about three- fourths of the 

 frontal length ; two or three outer and one or two inner elongate spines. 

 Avicularia large and longer than the width of a zooecium ; the beak long, 

 concave above and strongly hooked at the tip; situated about half way 

 up the side of the opesia but varying considerably in position. 



Ovicell in line with the zooecial axis, short and broad, shaped like a 

 hood and widely open, its attachment very broad. 



Verrill and Osburn recorded this species from Cape Cod, Massachu- 

 setts, northward to Labrador. O'Donoghue listed it from a number of 

 localities on the British Columbia coast and south to Puget Sound. Not 

 taken in the Hancock collections. 



Bugula uniserialis Hincks, 1884 



Bugula pedunculata O'Donoghue, 1925:17. 

 Bugula uniserialis, Hastings, 1930:705. 



A small slender species in which the zooecia are much narrowed on 

 the basal half and the opesia not more than half the zooecial length ; the 

 distal corners are sharply angulated but spines are wanting ; the avicularia 

 are attached at the proximal end and the peduncle is slightly longer than 

 usual in other species. According to O'Donoghue's figure (Plate 2, fig. 3) . 

 the zooecia of the two series are turned slightly outward instead of 

 toward each other as in most members of the genus. 



Hincks described the species from West Australia. O'Donoghue re- 

 described it as B. pedunculata from La Jolla, southern California, and 

 Hastings recorded it from two localities at Tagus Cove, Albemarle 

 Island, Galapagos, shallow water. It has not appeared in the Hancock 

 dredgings.
