306 BIOLOGICAL SURVEY OF 



LiCHENOPOEA HispiDA (Fleming), 1822. (Whiteaves, 1901, 

 p. 112, synonymy and Canadian records ; Verrill, 1875, p. 414 

 {Tubiilipora hispida + T. crates Stimpson), from Jeffrey's 

 Ledge ( Stimpson 's record for T. crates is from the Bay of 

 Fundy. ) Two colonies were taken at station 50. It is a very 

 widely distributed species, fomid on both shores of the Atlan- 

 tic, from the Arctic Ocean to Florida and the Mediterranean, 

 and in the Pacific as far south as the Strait of Fuca. 



The frontal surface of the zoarium is perforated by small 

 irregular pores which, under higher magnification, appear 

 stellate from the presence of small projections from the 

 periphery of the pore. 



Order CHEILOSTOMATA Busk 



Suborder ANASCA Levinsen, 1909 



Division I, Inovicellata Jullien, 1888 



Aeteidae Smitt, 1867 



Aetea Lamouroux, 1812 



Aetea angui:n^a (Linnaeus), 1758. PL 15, fig. 12. (Osburn, 



1912, p. 220, for New England records.) Apparently rare, 



only two small colonies being observed, both on algae attached 



to a pebble, dredging station 55. 



The species is found almost all over the world, in both cold 

 and warm seas. It is a stolonate form, growing over the 

 stems of hydroids, algae, and Bryozoa, and occasionally on 

 stones and shells. The zooecium consists in part of an en- 

 largement of the stolon and from this arises an erect tubular 

 portion which is slightly enlarged toward the upper end with 

 a flat, membranous area on one side. The stalk is annulated 

 and the swollen portion of the stonon minutely punctate. 

 There is no ovicell, but eggs are held for a time at least in 

 temporary membranous capsules at the dorsal side of the 

 aperture.
