A MONOGRAPH OF THE EXISTING CRINOIDS 181 



Carpenter remarked that the 2 Challenger specimens from Band a and Zamboanga 

 which were referred by him to coppingeri are linked together by another from Singa- 

 pore which was given him by Prof. Charles Stewart. 



The specimen from Singapore collected by Professor von Martens has 13 arms. 



Of the specimens collected by Mr. Svend Gad at Singapore, one has 27 arms 

 105 mm. long, and the cirri XIV, 25, 20 mm. long. Another has 22 arms 90 mm. long, 

 and the cirri XVIII, 30 mm. long. Another has 16 arms 65 mm. long; there are 3 

 llBr and 2 IIIBr series present; the cirri are XIV, 20-25, from 15 to 20 mm. long. 

 This specimen was parasited by a small gastropod {Sabinella capillastericola) attached 

 near the base of one of the arms [see vol. 1, pt. 2, p. 648]. Another has 14 arms 60 

 mm. long, and the cirri XV, 15 mm. long. Another has 12 arms 65 mm. long, the 

 2 lIBr series being on one ray; the cirri are XVI, 17-18, from 10 to 17 mm. in length. 

 This specimen bore another parasitic gastropod of the species mentioned above on 

 the dorsal side of one of the cirri near the base. Another specimen has the arms 

 70 mm. long, and the cirri XVI, 15 mm. long. Another has the arms 45 mm. long; 

 one IIBr series is just developing and is already giving off a IIIBr series. Other 

 specimens have 29, 26, 23, and 21 arms. 



Other specimens at hand from Singapore show the following characters: 



The arms are 22 in number, 75 mm. long. The IIIBr series are all internally 

 developed. There are 23-24 cirrus segments. 



The 29 arms are 80 mm. long. The IIIBr series are developed both internally 

 and externally. The centrodorsal is thin discoidal, bearing the cirri in a single irregular 

 marginal row. The dorsal pole of the centrodorsal is 5 mm. in diameter, and is 

 slightly sunken in the center. The cirri are XVIII, 20-22. 



The 22 arms are 100 mm. in length. One of the IIBr series is missing. The 3 

 IIIBr series are all internally developed. The cirri are XXI, 24-26, from 20 to 23 mm. 

 long. They are rather stout, especially basally, tapering rather rapidly as far as the 

 seventh segment, which is a transition segment, but becoming of more uniform width 

 from that point onward. 



One specimen has 23 arms 65 mm. long, and 2 others have 23 and 26 arms, in 

 both 80 mm. long. One has 20 arms 55 mm. long, and another 17 arms 50 mm. long. 



A very small specimen has 10 arms 40 mm. long. One arm is broken off at the first 

 syzygy, and a bud showing an axillary and 4 brachials is forming. The cirri have 

 14-15 segments, and are from 5 to 7 mm. long. 



Another very small specimen has 10 arms 35 mm. long. One of the arms is 

 broken at the first syzygy and an axillary followed by 3 brachials is appearing. The 

 cirri are of the adult type, but more slender than in large specimens. 



A specimen from Singapore in the British Museum has 14 arms 120 mm. long, and 

 the cirri 20 mm. long with 21 segments. 



Carpenter noted that the specimen from the Nicobar Islands collected by 4he 

 Galathea expedition has the brachials less strongly overlapping than the 2 specimens 

 from Anjer, Java. 



The specimen from the Malay archipelago in 183 meters has 40 arms about 70 

 mm. long.
