ACTINOMETRA, sp. 



Actinomelra, 1894, Walther, Einleitung in die Geologie als 

 historische Wissenschaft, p. 298. 

 Walther records an undetermined species of " Actiaoifnetra " as 

 A'ery common at Somerset, Queensland, in 15-22 meters. Probably 

 this is Comatula Solaris or C. rotalaria. 



ACTINOMETRA CUMINGII, Bell. 



Actinometra cumingii, 1884, Bell, Rep. Zool. Coll. H.M.S. 

 ''Alert," p. 167. 



Port Molle. — "A delicate specimen with 10 cirri, the cirri 

 having about 12 joints and no penultimate spine, and most of the 

 joints being a little longer than broad, is referred to this species. 

 Two of the arms which have undergone injury are now giving 

 rise to four and three arms respectively." 



If this description is accurate, this can only be a specimen of 

 Comahda rotalaria which is just undei'going adolescent auto- 

 tomy ; this is the only multibrachiate Atistralian Comasterid 

 with no dorsal processes on the cirri and with " most of the 

 [cirrus] joints a little longer than broad."
