42 A. E. Verrill — New Actinians. 



of either species were preserved by Dr. Stimpson. His origi- 

 nal drawings show no suckers. 



H. produeta ranges from S. Carolina to Cape Cod. Var. 

 albida, Cape Cod.* 



Eloactis brevicornis and E. Capensis are from Cape of Good 

 Hope.

Family Bunodactid^e Verrill = Bunodidce Gosse. 



JBanodactis V., new name = Bunodes Gosse (restr.) 



Bunodes (pars) Gosge, ]855, 1860, not of Eich. (genus of Euryptercidea), 1854. 



Unfortunately the name Bunodes was preoccupied, f as indi- 

 cated above, for a genus of eurypteroids, and some other name 

 has to be chosen for this well known genus of actinians. None 

 of the numerous groups recently established seem to corre- 

 spond with this genus, and I have, therefore, given it a new 

 name. 



This genus, as now limited, includes species that have from 

 12 to 48 pairs of perfect mesenteries,^: the number increasing 

 with age. All the larger mesenteries, except the directives 

 may bear gonads. The submarginal sphincter is prominent, 

 endodermal and circumscribed. The verrucse of the column 

 are intraseptal evaginations of the wall and serve as true adhe- 

 sive suckers ; some of the rows may reach the base. The wall 

 is imperforate, at least in the typical forms. The marginal 

 tubercles are simple and similar to those below, and are not 

 true acrorhagi, though sometimes pigmented distinctively. 

 The wall is thick and muscular. 



Bunodactis seems to include a considerable number of 

 species, widely distributed. Among these are the following : 

 B. verrucosa (Penn.) = gemmacea (type); B. Balli (Cocks); 

 B. Listeri (Johns.) ; B. glandulosa (Otto) = B. rigid 'a (And.) ; 

 B. thallia (Gosse) ; B. sabelloides (Andres), all from Euro- 

 pean seas ; B.pluvia (Dana) ; B. cruentata (Dana) ; B. oceliata 

 (Less.), and B. papillosa (Less.), West S. America ; B. inornata 

 (Ver.) Hong Kong ; and B. Japonica (Ver.) Japan. In 

 accordance with the usual custom, the change in the typical 

 generic name will make it necessary to change the family name 

 Bunodidce to Bunodaotidce. Tealiadse (Hert.) might be used, 

 were not Tealiaz, synonym of Urticina (Ehr., 1834, restricted). 



* Andres has based a new sp. (H. Elizabethce) on an incorrect outline figure of 

 this, in a popular work It is the same as H. albida.

 figs. 2-4, 1854, Bunodes lunula. The article is dated, at the end, Nov. 2,1853. 



X Y. and A. P. Dixon (Sci. Proc. Roy. Dublin Acad., ii, p. 310) have shown 

 that in B. thallia the number of mesenteries and their arrangement are remark- 

 ably variable, and that abnormal specimens are found with one or with three 

 pairs of directives and corresponding siphonoglyphs. I have found the same 

 variations in B. ttella, which usually has about 24 pairs of perfect mesenteries.
