REPORT ON THE CRINOIDEA. 255 



the same side. In arms which spring direct from the radial axillary the largest pinnules 

 are those of the fifth, sixth, and seventh brachials, which may reach 12 mm. long, and 

 consist of twenty smooth joints, most of them longer than wide, and the later ones 

 carinate. On the inner arm borne by a distichal axillary, the largest pinnules are those 

 of the fourth and fifth brachials; while on the outer arms these are little, if at all, 

 larger than that of the second brachial. But the third brachial always bears a small 

 pinnule. 



Disk naked and much incised ; sacculi very abundant on the disk, arms, and 

 pinnules. 



Colour in spirit, — the skeleton white, with patches or bands of a faded purple, and 

 the perisome darker. 



Disk 8 mm.; spread 17 mm. 



Locality. — Station 212, January 30, 1875 ; off Samboangan, Philippine Islands; 

 lat. 6° 54' N., long. 122° 18' E.; 10 fathoms ; sand. Three specimens. 



Remarks. — This is another of those dimorphic species which may or may not have 

 distichal series ; and it has therefore been assigned a place among the ten-armed forms of 

 Antedon, as noticed on pp. 194, 198. It is readily distinguished from the other members 

 of the Savignyi-gvowp, which have no palmar series nor lateral processes on the pinnules 

 like Antedon variipinna (PI. XL VIII. fig. 3). 



Antedon reynaudi has more numerous and spiny cirrus-joints and a longer syzygial 

 interval ; while there is a larger number of cirri in Antedon savignyi, also with spiny 

 joints, and the second syzygy is further from the calyx instead of being within the first 

 fourteen brachials as in Antedon anceps (PL XXXV. figs. 1, 2). The arrangement of 

 the lower pinnules of this type is rather peculiar. On the outer side of the ray the 

 distichal pinnule, when present, is much smaller than that of the second brachial above 

 it. That of the third brachial is again small ; but the next pair are little if at all larger 

 than that on the second. On the other hand, if there is no distichal pinnule, owing to 

 the arms springing directly from the radial axillary, the pinnule on the second brachial 

 is smaller than that on the fourth, and this again is smaller than those of the next three 

 joints (PI. XXXV. fig. 2). An arrangement intermediate between these two is found on 

 the inner arm of each pair borne on a distichal axillary, in which the fourth and fifth 

 brachials have the largest pinnules, that on the second, as the first pinnule on the arm, 

 being distinctly smaller.
