168 COLLECTIONS FROM MELANESIA. 



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 arras respectively. 

 Port Molle. 



21. Actinometra coppingeri. (Plate XYI. fig. B.) 



Centrodorsal small: 17-20 cirri in two rows, with from 17-20 

 joints, the fourth to sixth longer than broad, the rest shorter ; the 

 spines, including the penultimate one, obscure. 

 • First radials hardly visible, the second three times as wide as 

 long, partly in contact ; the axillary almost triangular, not a syzygy. 

 The specimen under examination has 12 arms, but the normal 

 number is probably 10. First and second brachials wider on their 

 outer than their inner side, the first in contact, the third a syzygy ; 

 it and the next two oblong ; the succeeding ones wedge-shaped and 

 the distal edges slightly dentated; further out the joints more 

 regularly oblong. 



Syzygies on the third and tenth, and then at about every fifth 

 joint. 



First pinnules on the third brachials longer than the second, and 

 the second a little longer than the third ; the fourth again rather 

 longer. The succeeding ones of a fair length. 



Length of arms about 70 millim., of cirri 7'5 millim. ; diameter of 

 disk 4/5 millim. 



Colour creamy white. 



Flinders, Clairmont. 



22. Actinometra jukesi. 

 P. H. Carpenter, P. P. S. 1879, p. 390. 



A technical description of this species will be given by Mr. P. 

 Herbert Carpenter in his Eeport on the Comatulidae of the ' Chal- 

 lenger' Collection. It is evidently a common form. 



Albany Island ; Prince of Wales Channel. 



23. Actinometra parvicirra. 



Actinometra parvicirra (Muller), P. II Carpenter, Notes Leyd. Mtu. 

 hi. p. 204, ibique citata. 



A small specimen, from Warrior Reef, was determined for me by 

 Mr. Carpenter ; another from Port Molle has less than 20 arms, as 

 in some of the specimens in the Paris Museum. It is of interest to 

 note that this appears to be, like A. carinata, a species of exceedingly 

 wide range, for Mr. Carpenter found two specimens of it from Peru 

 in the collection of the Hamburg Museum.
