3. ANTHELIA PURPURASCENS. (Ehrenberg.) 



A. extus e violaceo allricans ; tentaculis intus violaceo-purpurascentibus, 

 papillis utrinque 3-seriatis. 



Exterior pale violet; tentacles purplish violet within ; papillae on each 

 side in three series. , 



Red Sea. Ehrenberg. 



Anthdia p/irpitrascens, Ehrenberg, G. xxi., sp. 3. Savigny's pi. 1, fig. 5, E<ryp. 

 Polypes, is referred to this species with a query by Ehrenberg. 



4. ANTHELIA DESJARDIANA. (Templeton.) Dana. 



A. pallidc livido-ccEmka, late effusa, basi " crassa ; polypis valde pro- 

 minentibus, lateribus horizontaliter rugatis. 



Pale livid blue; widely spreading, with the base of an inch thick ; 

 polyps very prominent, sides horizontally wrinkled. 



Isle of France. Templeton. 



The papilla3 of the tentacles, as represented by Templeton, are very 

 short, and the polyps are about half an inch in height. The animals, 

 however, do not appear to have been fully expanded when figured, 

 and to this may be owing the encircling wrinkles of the polyp. 



Xenia Desjardiana, R. Templeton, Zool. Trans, of London, ii. 25, with a plate. 



NOTE. Savigny figures two other zoophytes resembling the Anthelice in habit, which 

 Ehrenberg suggests may be Sympodia. 



The Clavidaria violacea, of Quoy and Gaymard (Voy. de 1'Ast., iv. 262, pi. 21, figs. 

 13-16), may be an Anthelia partly expanded. The C. viridis of the same (p. 260, pi. 

 21, figs. 10-12), resembles a Cornularia, as stated by Milne Edwards. But according 

 to Quoy and Gaymard, these species have the corneous tubes of the Cornularia;, with 

 the coalescence below into a plate which belongs to the Antheliae, characters which 

 would sustain the genus as proposed by them.
