One of the specimens from Ceylon in the Museum of Comparative Zoology has 

 47 arms. One of the IIBr series and 2 of the IIIBr series are 2. There are about 

 a dozen nonfunctional cirri, which are mostly small. 



Another from Ceylon has 43 arms. Two of the IIBr series are 2. There are 

 VI small nonfunctional cirri. 



A third individual has about 40 arms. Three of the IIBr series are 2. The 

 centrodorsal is irregularly pentagonal in shape and bears some rudimentary cirrus 

 sockets. 



The other 2 specimens from Ceylon have 40 and 54 arms. 



Of the 2 specimens from Tuticorin in the British Museum, 1 has 68 arms; there 

 are IV cirri, one large and the rest diminishing in size, the larger having 13-14 seg- 

 ments. The other has 43 arms and the cirri XV, 14-16. 



The specimen from the Indian Ocean (probably the Dutch East Indies) col- 

 lected by Mr. George Bennett has 33 arms. 



The specimen from Port Blair, Andaman Islands, has 34 arms 110 mm. long. 

 All 10 of the IIBr series and 14 IIIBr series are developed, the latter in 1, 2, 2, 1, 

 order, except where there are 4 on a ray. One of the IIIBr series is 2, the others 

 being 4 (3 + 4). 



The specimen from Atjeh was described by Hartlaub as having a medium-sized 

 centrodorsal and 48 arms, with all the division series beyond the IBr series 4 (3 + 4). 



The specimen from the southern portion of the Malacca Straits has 51 arms 

 140 mm. long. Eleven IVBr series are present. Four of the IIBr series are 2, as 

 are 3 or 4 of the outer division series. There remain 1 cirrus 10 mm. in length with 

 14 segments, and 3 very rudimentary cirri. This specimen agrees perfectly with the 

 magnificent specimen from Bowen, Queensland, in the Copenhagen Museum. 



The specimen from Singapore collected by Mr. Svend Gad has 41 arms 100 mm. 

 long. The IIBr and IIIBr series are all 4 (3 + 4), and the single IVBr series is 2. 



Gisl6u said that in a specimen from Java, which possibly represents a new species 

 on account of the very long, slender, and well-separated arms, the terminal combs 

 occur on every second pinnule and reach at least to the thirty-fifth, whereas in the 

 specimen from the Bonin Islands they reach only as far as the eleventh pinnule. 



The larger specimen from Siboga station 322 has 49 arms 130 mm. long. All of 

 the IIIBr series are present. Of the IIBr series, 6 are 2 and 4 are 4 (3 + 4), the latter 

 all occurring on 2 postradial series. The centrodorsal is greatly reduced, small and 

 sharply stellate. The division series are broad and are in close lateral apposition and 

 sharply flattened against each other. The smaller example has 3 of the postradial 

 series undergoing adolescent autotomy. One partially developed cirrus remains on 

 an irregularly pentagonal centrodorsal. 



The example from Siboga station 209 has 42 arms 95 mm. long. Five of the IIBr 

 series are 2. There are VII cirri. 



The specimen from Siboga station 149 has 36 arms 110 mm. long. All the IIBr 

 series are 2. One of the IIIBr series is 2, the others being 4 (3 + 4). The centro- 

 dorsal is greatly reduced, pentalobate, bearing at the tip of one of the lobes a single 

 cirrus 9 mm. long with 14 segments. 



Of the 17 specimens from Siboga station 89 the largest has 39 arms, of which the 

 anterior are 111 mm. and the posterior are 70 mm. in length. All the division series
