BuGULA FLABELLATA (Thompsoii), 1847. PI. 8, fig. 4. Os- 

 burn, 1912, p. 225, synonymy and references.) Not common, 

 not found at shore stations but dredged on shallow stony 

 bottoms at stations 21, 27, 90, 93, 126, 127. It is a well-known 

 species on both sides of the Atlantic, extending southward 

 to Florida on the American coast, and from the British 

 Islands to the Mediterranean on the coast of Europe. It 

 also occurs on the Pacific coast of North America at San 

 Diego, California. Dr. Alice Robertson (1900, p. 321) listed 

 it for Sitka, Alaska, but later (1905, p. 271) described this 

 form as a new species, B. piigeti. 



Mt. Desert Island apears to be about the northern limit 

 of the species on the American coast, as no collector has 

 reported it from Canadian waters. 



There seems to be a peculiar hiatus in the distribution of 

 this family in northern New England and eastern Canada. 

 There are six species common about Cape Cod, including this 

 and the following, and about ten are known from more north- 

 ern waters. Whiteaves recorded only Bugiila murrayana and 

 two species of Kinetoskias from eastern Canada, Osburn 

 (1912, p. 277) added B. cucidlifera, and Cornish mentions but 

 one species from Canso, Nova Scotia (Bugula sp. = ? J5. cu- 

 Gulifera Osburn).

 Dendrobeania murrayana (Johnston), 1847. PL 4, fig. 8; 

 pi. 8, fig. 3. (Osburn, 1912, p. 226 {Bugula), for synonymy 

 and references; 1912a, p. 277 (Bugula), additional Canadian 

 records; AAHiiteaves, 1901, p. 93 (Bugula), for Canadian rec- 

 ords.) One of the most abundant species, occurring especially 

 on hard bottoms, attached to stones and shells ; common also 

 on stony shores. Taken at six shore stations and forty-one 

 dredging stations. The more slender variety (fruticosa 

 Packard) occurred in some numbers along with the typical 

 form. The large lateral avicularia are usually wanting, and
