440 TUBULIPOEIDJE. 



very irregularly and often tliickly distributed over its 

 surface. 



In certain stages of growth, before the development of 

 the discoid head, the erect stalks terminate above in a 

 number of long, curved, irregularly disposed tubes. Busk's 

 figure (B.M. Cat. iii, pi. xxxii. fig. 3) has the appearance of 

 being drawn from an immature specimen. 



The Tubipora penicillata of Fabricius differs from the 

 present species in having the tubes towards the capitulum 

 aggregated into fascicles, and disposed on its surface in 

 radiating series. Smitt regards it as distinct, and has 

 figui'ed both forms from northern specimens. It must be 

 noted, however, that his figure of T. penicillata bears a 

 very close general resemblance to our West-of-England 

 species ; and as there is not unfrequently in T. fungia a 

 tendency more or less marked towards a radiate arrange- 

 ment of the zocBcia on the capitulum, it may perhaps be a 

 question how far the separation of the two is waiTanted. 

 In the absence of specimens of the penicillata form^ the 

 point cannot be determined. 



Habitat. On shells and stones generally from deep 

 water. 



Localities. From the Eddystone Lighthouse to the 

 Deadman Point (Couch) : on stone from 40 fathoms off 

 Polperro ; Torbay (T. H.) : Wick and Peterhead (C. W. P.) : 

 Banff (Busk) . 



Geographical Distribution. Finmark, 50 fathoms 

 (Goes and Malmgren) : Greenland (Llitken) : Hamilton's 

 Inlet, Labrador ( Wallich, /rV/e Busk).
