758 " THETIS " SCIENTIFIC RESULTS. 



Specimens in the Australian Ifitseum Co/lection. — Port Deni" 

 son, Queensland — Two immature specimens ; one has nineteen 

 arms about 100 mm. long, the other twenty-four arms about 120 

 mm. long. The centrodorsal is much reduced in size. 



Additional Australian Records. — The "Challenger" dredged 

 tliis species in 10° 30' S. lat., 142" 18' E. long. (Prince of Wales 

 Channel), in 8 fathoms, and I have recorded a specimen from 

 Bowen, Queensland, which is in the collection of the University 

 of Copenhagen, having been originally obtained from the GrodefTroy 

 Museum. There are two unrecorded specimens from Torres 

 Strait in the U. S. National Museum. At the British Museum 

 I examined specimens from Cape York, from Torres Strait, from 

 North-eastern Australia, and from Holothuria Bank, in 34 

 fathoms. 



Distribution. — Comanthus valida ranges from northern Aus- 

 tralia northward to the Philippine Islands, eastward to the Solo- 

 mon, Fiji, and Tonga Islands, and westward to Ceylon. 



Ketnarks. — An examination of the types af Bell's Actinometra 

 annulata (at London) and of Carpenter's Actinometra meyeri (at 

 Hamburg) has shown- that they are identical with the Actino- 

 metra valida described in (he "Challenger" Report, and with 

 the Comanthus intricata which I described in 1908. The occur- 

 rence of rather more II Br 2 series than usual in the type of 

 Actinometra valida prevented Carpenter from discovering its 

 affinities with A. meyeri and A. annulata.
