The specimen from Siboga station 296 has 15 arms; 1 of the IIBr series is 2; 

 this example is of small size. 



The specimen from Siboga station 282 has 20 arms. 



The specimen from Siboga station 285 is very small with 10 arms. 



One of the specimens from Siboga station 144 has 18 arms, there being no IIBr 

 series on one ray; the other has 17 arms 95 mm. long and is evidently young. 



Of the 2 specimens from Ternate, which I examined at Hamburg, 1 has 15 and 

 the other 17 arms; the brachials of both have very strongly everted distal edges. 



The specimen collected by Professor von Martens at Amboina has 20 arms 115 

 mm. long. 



Of the 3 specimens collected by Dr. Th. Mortensen at Amboina in about 1 meter, 

 1 is large with 19 arms 135 mm. long; of the 9 IIBr series present 5 are 4 (3+4) and 

 4 are 2. A second example has 21 arms 130 mm. long. The single IIIBr series, 

 which is internally developed, is 2. On the 2 arms following this IIIBr series the 

 first syzygy is between brachials 30 + 31 on one and between brachials 33 + 34 on the 

 other. The third specimen has 18 arms; there are 8 IIBr 4 (3 + 4) series. 



The specimen from Amboina in about 2 meters had probably 20 arms which 

 are 90 mm. long; 10 IIBr 4 (3 + 4) series are present. The centrodorsal is thin 

 discoidal with the concave dorsal pole 4 mm. in diameter. The cirri are XVI, 20-22, 

 from 15 to 17 mm. long, most of them more or less undeveloped. 



The specimen from off Neira, Banda, in 13 meters has 27 arms 130 mm. long. 

 Of the 10 IIBr series present 8 are 4 (3 + 4) and 2 are 2; the 7 IIIBr series are all 



3 (2 + 3). The cirri are XX, 23, 18 mm. long. Of the 5 specimens from off Neira in 

 about 15 meters, 1 has 20 arms 90 mm. long; of the 10 IIBr series 6 are 4 (3 + 4) and 



4 are 2. One has 19 arms 100 mm. long; there are 8 IIBr series, 6 of which are 

 4 (3 + 4) and 2 are 2; there is a single IIIBr 2 series internally developed. Another 

 has 19 arms 85 mm. long; of the 9 IIBr series 3 are 4 (3 + 4) and 6 are 2. A specimen 

 with 19 arms has 3 IIBr 4 (3+4) series, 5 IIBr 2 series, and a single IIBr 3 series. 

 The last specimen has 19 arms; of the IIBr series 5 are 4 (3+4) and 4 are 2. Of the 

 8 specimens from off Banda in about 20 meters, 1 has 24 arms; 3 of the IIBr series 

 are 4 (3 + 4), 6 are 2, and 1 is 3 (2 + 3) ; there are 4 IIIBr series, 2 of which are externally 

 developed on a single postradial series, the other 2 being on a single IIBr series; of 

 the latter the external is 2 (1+2) and the internal is 3 (2 + 3), as are the other 2. 

 One specimen has 22 arms 150 mm. long; of the 10 IIBr series 7 are 4 (3+4) and 3 are 

 2 ; there are 2 IIIBr series, 1 internal and the other, following a IIBr 2 series, external. 

 The cirri are XX, 24, 20 mm. long. One specimen has 21 arms; of the 10 IIBr series 

 8 are 4 (3+4) and 2 are 2; the single IIIBr 3 (2 + 3) series is internally developed. 

 One specimen has 20 arms with 10 IIBr 4(3+4) series. Two specimens have each 

 19 arms with 9 IIBr 4 (3+4) series; the arms are SO mm. long in one and 90 mm. long 

 in the other. One specimen has 19 arms 160 mm. long; of the 9 IIBr series 8 are 

 4 (3+4) and 1 is 2. This example is not larger than those preceding, but the arms 

 are lengthened and attenuate. The last specimen is small with 10 arms. The 

 specimen from about 25 meters has 19 arms 80 mm. long; there are 9 IIBr 4 (3+4) 

 series; the distal edges of the brachials are rather strongly everted and abundantly 

 armed with small spines. The specimen from Lontor has 15 arms 90 mm. long; the
