616 ZOOPHYTES. 



Akyonium stellatum, Milne Edwards, Ann. des Sci. Nat., iv., 2d ser., 1835, pi. 16. The 

 figure represents a specimen an inch and a half in height, a fourth of an inch at base, 

 enlarging above, and with a few rounded lobes or short branches. The polyps are larger 

 than in the palmatum ; the species differs from that also in the spicula about the soft 

 part of the polyps. Also, Cuvier, Reg. Anim., 1837, pi. 94, fig. 2. 



6. ALCYONIUM SPHEROPHORA. (H. <$ Ehrenberg.} Dana. 



A. ejfusum, subhemisphericum, membrana marginali sterili, superfaie 

 cerebriformi, brevissime lobala, lobulis 2-3'" latis, semiglobosis, divi- 

 duis ; pallidum, poly pis fuscis. 



Effuse, subhemispherical, membrane of the margin sterile, surface 

 cerebriform, very short lobed; lobes 2 to 3 lines broad, semiglobose, 

 subdividing; pale, polyps fuscous. 



Red Sea. Ehrenberg. 



The cerebriform hemispherical surface, with short rounded lobes, 

 two to three lines thick, are the peculiar characteristics of the species. 



Lobularia spherophora, Ehrenberg, G. xxv., sp. 4. 



The Akyonium tuberculosum, of Quoy and Gaymard, (Voy. de 1'Ast., iv. 274, pi. 23, 

 figs. 4, 5,) as figured by them, is similar to the sp/ierophora of Ehrenberg. They de- 

 scribe it as follows : " A. brevi-pedunculatum, incrustans, coriaceum, lutescens aut 

 griseum ; mamillis convexis, subrotundis ; polypis sessilibus ; tentaculis longis, graci- 

 libus." " Espece dure, coriace, formee de mamelons arrondis, serres, groupes sur un 

 court pedicule, recouvrant les corps marins ; forme des groupes qui n'excedent pas de 

 beaucoup la grosseur du poing." We suspect still that this may be identical with a 

 Tonga species obtained by the Expedition, which we have referred to under the A. 

 brachycladum. 



The Alcyonium spongiosum, of Esper (Pflanz., iii. 20, tab. 3), is a stipitate species, 

 having similar characters to Ehrenberg's spheropfiora. See farther, A. brachycladum. 



6. ALCYONIUM PAUCIFLORUM. (H. 4- Ehrenberg.} Dana. 



A. substipitatum, supra lobatum, suberectum ; lobis compressis, obtusis, 

 4'" crassis et fere " altis ; superficie subtilissime areolata, glabrd ; 

 polypis raris, sparsis ; fuscum. 



Substipitate, lobately divided, suberect; lobes compressed, obtuse, 4
