A MONOGRAPH OF THE EXISTING CRINOIDS 145 



syzygial pairs are counted as units. Syzygies occur (as an example) between brachials 

 3+4, 11 + 12, 17+18, etc., and distally at intervals of 3 or 4 (or 5) muscular articulations. 

 PI is smooth, 5.5 mm. long with 15 segments. P 2 is from 9 to 9.5 mm. long with 19 

 segments of which the fifth-twelfth are from two to two and one-half times as long 

 as broad and bear spiny prominences on the distal ends; the tip of the pinnule is 

 usually smooth. P 3 is from 7 to 7.5 mm. long with 14 or 15 segments, and is similar 

 to P 2 . P 4 is 4 mm. long with 12 segments; this and the following pinnules are smooth. 

 The distal pinnules are 8 mm. long with 20-22 segments of which the first and second 

 are short and stouter than those succeeding, the distal end of the second therefore 

 forming a weak notch against the outer segments, which are longer, from 2 to 3 times 

 as long as broad; the last segment is provided with microscopic dorsal hooks. The 

 disk has been thrown off. The cirri and the division series are white. The distal 

 parts of the arms are spotted with red brown. The proximal pinnules are white, 

 the other pinnules light brown-violet with strongly colored sacculi, of which there 

 are about four pairs to each segment. 



The specimen from off Yenoshima in 146-283 meters has 20 arms. 



One of the specimens from Misuka has 17 and the other has 20 arms. 



The 7 specimens labeled Sagami Bay collected by Dr. Haberer are small and of 

 medium size, the largest having the arms 80 mm. long. One has 15 arms, 2 have 

 19 arms, and 4 have 20 arms. 



Three of the specimens from Japan in the Museum of Comparative Zoology 

 collected by Alan Owston have 20 arms 55-65 mm. long. The three others have 

 also 20 arms. 



The specimen from off Hondo (Nipon), Japan, in the Copenhagen Museum was 

 described by the author as a new species, Cyllometra anomala, in the following terms: 

 The centrodorsal is a thick disk with a broad slightly concave polar area; the cirrus 

 sockets are arranged in two irregular and crowded more or less alternating rows. 

 The cirri are XXX, 21-28 (usually about 25), from 10 to 12 mm. long. The first 

 six or eight segments are not so long as broad, and the remainder are about as long 

 as broad. The dorsal surface of the segments is smooth, rarely in the terminal two 

 or three with a slight trace of a minute central tubercle. The opposing spine is prom- 

 inent, though small, reaching to not more than about one-third the width of the 

 penultimate segment in height. The terminal claw is rather longer than the penulti- 

 mate segment, and is moderately curved. The radials are concealed by the centro- 

 dorsal. The IBr t are slightly trapezoidal, very short, four times as broad as long 

 or even rather broader. The IBr 2 (axillaries) are about half again as broad as long 

 and, like the IBri, are free laterally. Seven IIBr series are present, one 2 and the 

 remainder of 4 segments with a synarthry between the first and second and between 

 the third and fourth. The IIBr 2 , except when axillary, always bears a pinnule. 

 There are three IIIBr series of 2 ossicles each of which the second is not an axillary. 

 The 17 arms are about 55 mm. long. P a is present on about half of the arms. The 

 color is white, the cirri with narrow bands of light purple, the polar area of the centro- 

 dorsal deep purple, the division series and discoidal lower brachials with a median 

 line of purple, the remainder of the arms crossed by purple bands about equal to 

 one brachial in width separated by white bands of the same width.
