1-J^ ACTlN'OMI-rriiA TYPICA. 



The genus Phanogevki was established by Lovéu iii 1866 

 for the reception oJ some remarkable Comat.ulae from Sin- 

 gapore '). They are especially characterised by having a 

 more or less stellate centroilorsal which bears few or no 

 traces of cirrhus-sockets , and occupies but does uot com- 

 pletely fill the central space within the radial pentagon. 

 The same peculiarity was noted by Dr. Liitken in an Ac- 

 tinometra of the Godeffroy collection from Fyi, to which 

 he gave the M.S. name Actinometra stellata ; and duplic- 

 ates of the type have been distributed from the (lodeffroy 

 Museum under this name. Having examined some of these 

 duplicates and also , by the kindness of Prof. Loven , his 

 original specimens of Fhanogenia I am disposed to regard 

 the two types as identical. During my visit to Copenhagen 

 last autumn I was glad to learn that the same idea 

 had also occurred to Dr. Liitken , with whom I am pleased 

 to find myself in accordance as to the generic position of 

 the type. 



In my preliminary report '■) upon the Comatulae of the 

 » Challenger" Expedition I pointed out that the peculiar 

 stellate condition of the centrodorsal of P/ia?«or/enm » appears 

 to be one of the concluding stages of a long series of chang- 

 es in the shape and relations of the centrodorsal , which 

 do not commence until some time after the loss of the 

 stem , and the entry upon the free state of existence." I 

 also gave some account of these stages as exhibited by Ac- 

 tinometra jukesii and by other species of the genus ^). But 

 not having seen Phano(jenia at that time I felt unable to 

 refer it to Actinometra in the face of Loven's description , 

 » Os centrale sulci tentaculiferi fere quales in Ante- 

 done.'' Since my examination of it, however, I do not
