636 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.39. 



Subgenus COMANTHINA. 

 COMANTHUS (COMANTHINA) SCHL-EGELU (P. H. Carpenter). 



Ulugan Bay, Palawan. — One fine large specimen, with about one " 

 hundred arms 155 mm. long; seven large functional cirri 13 mm. in 

 length remain, all on the anterior semicircumference of the centrodorsal. 



Examination of the type of Carpenter's Actinometra sclilegelii sit 

 the Leyden Museum has disclosed the fact that it is exactly the same 

 thing as the Actinometra nohilis and Act. regalis described in the Chal- 

 lenger report. Carpenter having overlooked at the time the charac- 

 teristic arm structure which he described later in Act. nohilis. 



Subgenus COMANTHUS. 



Specific Group VALIDIA. 



COMANTHUS (COMANTHUS) ANNULATA (Bell). 



Station 5321. — One specimen with forty arms; one of the IIIBr 

 series is 2. 



Station 5599. — One specimen with forty-two arms; two of the 

 IIIBr series are 2. Neither of these specimens have any cirri. 



Tulayan Island. — One specimen with forty-six arms 100 mm. long; 

 the brachials are rather strongly overlapping; one of the IIIBr 

 series is 2, another is 8 (3 -h 4 ; 7 4-8); there are three cirri remaining. 



Thanks to the kindness and courtesy of Prof. Jeffrey Bell I have 

 recently been able to examine the type of his Actinometra annulata 

 at the British Museum, and I find that it is the same species as that 

 later described in the Challenger report as Actinometra valida. 



COMANTHUS (COMANTHUS) PARVICIRRA (J. Muller). 



Station 5413. — One specimen with nineteen arms 95 mm. long; one 

 of the IIBr series bears two IIIBr series; twelve cirri are present 

 in a partially deficient row. 



Station 5414- — One specimen with fifteen arms 95 mm. long; 

 there are five IIBr series present, three 2, two 4 (3-f-4); the arms 

 are long and slender with the brachials more strongly overlapping 

 than usual; two small cirri 5 mm. long remain on a centrodorsal 

 barely raised above the radials. 



On the basis of Carpenter's statements in the Challenger report 

 I have hitherto called this species rotalaria, but upon examining the 

 types of rotalaria at Paris I find that it is the same thing as the form 

 called jukesii by Carpenter and paucicirra by Bell. Parvicirra is the 

 next available name.
