REPORT ON THE CRINOIDEA. 151 



collection which have come into my hands. Three years later (1872) it was obtained by 

 the ill-fated "Tegetthoff " 5° west of Nova Zembla, and was minutely described by von 

 Marenzeller 1 who referred it to Antedon celticus, Barrett, sp. Little was then known of 

 the latter form, except for the very incomplete description of it which had been given by 

 Barrett, and for Sir Wyville Thomson's incidental references to the numerous examples of 

 it which had been dredged off the north coast of Scotland by the "Lightning" and 

 " Porcupine." 



Von Marenzeller, regarding his Arctic specimen as identical with Barrett's type, 

 gave a careful description of them which enabled Duncan and Sladen to recognise the 

 same form among the Comatulse dredged by Sir George Nares's Arctic Expedition of 

 1875-76. These were well and carefully described by Sladen, 2 who was the first to 

 figure the type, though still under Barrett's specific name " celtica." He used this 

 designation with some hesitation, however, owing to the prevalent want of knowledge 

 respecting Barrett's species ; and after writing his description of the more northern form 

 he saw for the first time some examples of the true Antedon celtica, which he recognised 

 as altogether distinct from the Arctic type. He therefore inserted a note to this effect, 

 but did not alter the name under which the latter had been described by both von 

 Marenzeller and himself. It will be shown further on that Barrett's species has proved 

 to be identical with the long but little known Antedon phalangium, Midler, sp.. of the 

 Mediterranean, and the specific name celtica being therefore unoccupied, I thought at 

 first 3 that it might conveniently be retained for the type described under this name by 

 von Marenzeller and Sladen respectively. This course, however, has seemed undesirable 

 for many reasons ; and in compliance with the wishes of both the above named naturalists 

 I propose to give it a new name altogether. I have therefore chosen one indicative of the 

 character by which the species is most easdy distinguished from Antedon eschrichti, viz., 

 the markedly quadrate shape of the middle and outer arm-joints, as seen in PI. XXVII. 

 figs. 5-7, and in the woodcut, fig. 4 on p. 154. 



Thanks to the kindness of Dr. von Marenzeller I have been able to examine the 

 single individual dredged by the " Tegetthoff," and I am satisfied that Sladen was right 

 in identifying it with those which he described from Smith's Sound and Robeson Channel. 

 Another example was dredged by the " Valorous " in Davis Strait in 1875, and when the 

 Challenger Comatulse came into my hands I found the same type among a quantity of 

 specimens of Antedon eschrichti from Station 4S on the Le Have Bank (51 fathoms). 

 The species was twice taken by the "Triton" (1882) in the cold area of the Fseroe 

 Channel. The "Willem Barents" met with it in 1880 near the locality of the 

 "Tegetthoff" dredging; and it was twice obtained by the "Varna" in the Kara Sea
