LOBOPHYTUM PAUCIFLORUM, Ehr., var. VALIDUM, Marenz. 



Lobophytum pauciflorum, Ehr., var. validum, Marenz., Zool. 

 Jahrb., Bd. i., p. 367, pi. ix., fig. 12, a, b, c. 



One specimen 80 mm. long by 52 mm. wide, the sterile column 

 is 25 mm. high, with a somewhat even surface, excepting at one 

 point, where it exhibits a few transverse wrinkles. 



The capitular margin is slightly thickened, and a little revolute 

 .in some parts. 



The lobes of the capitulum are abruptly rounded at the summits, 

 they are about ten in number and vary from 15 to 25 mm. in 

 height, 15 to 40mm. in width, and from 7 to 10mm. in their 

 least diameter. 



The autozooids are 2 mm. apart, the walls surrounding the 

 orifices are slightly raised, and a shade darker in colour than the 

 rest of the surface. 



The siphonozooids are numerous, small, and scarcely visible to 

 the unassisted eye ; there are from five to seven between two 

 autozooids. 



The spicules do not differ from those figured by Marenzeller. 



The specimen in spirits is a dark stone colour. 



LOBOPHYTUM HEDLEYI, sp. nov. 

 (Plate x., figs. 2o-7t.) 



There are three examples, exhibiting great variation in the 

 lobation of the capitulum. 



In the larger specimen the sterile column is complete, rigid, 

 and harsh to the touch, longitudinally plicate, and measures 

 50 mm. in diameter and 35 mm. in height. 



The capitulum consists of about twelve subflabellate lobes 

 from 20 to 40 mm. high, 25 to 45 mm. wide, and from 5 to 8 mm. 

 thick. 



The primary lobes are divided into three or four secondary 

 lobes, 10 to 15mm. high, and 5 to 10mm. wide. Many of the 

 broader lobes have a longitudinal fold commencing at the base 

 and continued to the subtruncate apex. 



In the two smaller examples, both the primary and secondary 

 lobes are much narrower, the latter often digitate, compressed, 

 or subcylindrical, with evenly rounded summits, the wider lobes 

 exhibit a rather broad median longitudinal groove on at least one 

 side ; on the widest lobes the grooves are present on both sides. 

 The primary lobes are from 8 to 30mm. wide, 10 to 25mm. high, 

 and from 3 to 7 mm. thick ; the secondaries from 5 to 20 mm. 

 high, 5 to 10 mm. wide, and from 2 to 5 mm. in their narrow 

 diameter,
