The 19 arms are up to 40 mm. in length. The brachials up to and including the 

 fifth are discoidal, to about the eighth without distal prominences, then wedge- 

 shaped with produced distal ends which have dentate or Imotty collarlike borders. 

 The number of the brachials is from 50 to 70. 



The first syzygy on the undivided arms is sometimes found between brachials 

 1+2 the second between brachials 3 + 4, and the thu-d about the twelfth brachial. 

 But in one case, at least, the third syzygy is between brachials 5 + 6. On 3 arms the 

 first 2 syzygies are between brachials 3+4 and 6 + 7. 



Pi is 9 mm. long with about 30 segments. P2 is 7 mm. long. P3 is 5 mm. long. 

 P4 is 3 mm. long. The length of the following pinnules increases to 5 mm. The 

 distal pinnules have 12-15 segments. The pinnules as far as P4 have combs con- 

 sisting of about 5 teeth, which are rolled tightly mto little balls, and combs occur 

 here and there as far as the eleventh pinnule. The distal pinnules have recurved 

 spines dorsally on the outer segments, and the other pinnules are finely spinous 

 dorsally. 



Gisl4n originally described this specimen under the name of Comaster multifida, 

 later reidentifying it as Comanthus parmcirra. But as is shown by his figure the 

 cirri are those of a species of Capillasterinae, and the individual must therefore 

 belong to a species either of Capillaster or of Comatella. 



One of the IIIBr series is 3 (2 + 3); of the 6 IIBr series, 3 are composed of 4 

 ossicles. The characters are partly those of the genus Capillaster and partly those 

 of the genus Comatella. The species actually represented is undoubtedly Capil- 

 laster multiradiaia, which is more or less frequently subject to great and disconcerting 

 irregularities in the division series, and in the distribution of the syzygies. 



The single specimen secured by Dr. Hubert Lyman Clark at Mer, Murray 

 Islands, has 19 arms about 100 mm. long, and the cirri XXI, 20-24. The color in 

 life was "oral surface, black; dorsal surface, brown, the joints between the arm 

 segments much darker; whole dorsal surface, including the cirri, heavily silvered or 

 frosted with white." As preserved, dried, it is uniform light gray. 



The specimen from Blanche Bay, New Britain, has 12 arms which expand very 

 rapidly to about the sixteenth brachial, then taper distally. The brachials are 

 shaped essentially as are those of Comatula Solaris, being strongly convex externally 

 with a strongly concave distal edge; they are also strongly triangular instead of 

 being more or less oblong as usual. 



The specimen from St. Matthias Island collected by Dr. G. Duncker is typical. 

 The specimen from the same locality collected by Herr Schode is small. 



Dr. P. H. Carpenter noted that in the type specimen at Lund the centrodorsal 

 partly conceals the IBri which are closely united laterally, and the IBr axillaries 

 are more triangular than in the Lamarckian type of Jimbriata. The position of the 

 second syzygy varies from between brachials 21 +22 to between brachials 40 + 41. 



Two of the three specimens without locality in the British Museum are highly 

 irregular and will be noticed under the abnormal specimens. 



Abnormal specimens. — One of the individuals from the Malay archipelago in 

 292 meters is most extraordinarily irregular. It has 36 comparatively stout arms 

 about 70 mm. long. The division series are broad and are in close lateral apposi-
