BEYOZOA FROM FEANZ-JOSEP LAND. 177 



of very irregular shape and size, as figured by Smitt (pi. 11. fig. 4) ; 

 through this wall pass the ovicellular duets with funnel-shaped 

 openings. The zooecial tubes have the median longitudinal rib 

 well marked, and this usually forms a median acuminate process, 

 though sometimes the two sides are acuminate instead. Typical 

 Liclienopora verriicaria, L., occurs from Naples and other 

 Mediterranean localities, though in one form which I at first 

 named L. verrucaria the rays are more distinct, and perhaps it 

 is a variety of L. radiata, Aud. 



Heller, when referring to Tubulipora verrucaria, L., gives 

 Madrepora verrucaria, Fab., as a synonym, but, judging from 

 the references to Milne-Ed wards' s and Johnston's figures, it is 

 probable that Heller was describing Tuhulipora Jiahellaris, Johnst. 

 He also gives M. verrucaria. Fab., as a synonym of his Discopora 

 hispida, which may be Lichenopora hispida, Flem. Liclienopora 

 verrucaria, L., has been very carefully studied by S. F. Harmer, 

 with special reference to the ovicell, and the results are given 

 in his paper " On the Development of Lichenopora verrucaria," 

 Quart. Journ. Micr. Sci. n. s. \^ol. xxxix. p. 71, pis. 7-10. Eidley 

 mentions and figures a closure with a central opening, and thinks 

 that Smitt had mistaken some of these for ovicellular ducts.
