middle of tlieir juuctiou with the axillaries. These lire oue and a 

 half times as long as the preceding joints, widely pentagonal, with 

 open distal angles, and also slightly raised in the middle of the 

 hinder edge. 



30 arms, each of 1504- joints. The rays may divide three 

 times : the first division of three joints, the axillary with a syzygy; 

 and the second of two joints, the axillary without a syzygy. 

 The first joints after each axillary rhomboidal and closely united 

 laterally, with the distal edge very slightly incised to receive the 

 convex hinder edge of the next joint. Third brachial a syzygy, 

 short and oblong. The next four or five joints also short, with 

 somewhat oblique terminal faces, and slight backward projections 

 alternately on the inner and outer sides. The fourth and sixth 

 joints are thus longer on their inner sides, and the fifth and seventh 

 on their outer ones. Following joints short, bluntly wedge-shaped 

 and overlapjnng, nearly twice as wide as long, and becoming more 

 oblong about the middle of the arm. 



Eirst syzygy on the third brachial ; the next from S-16, usually 

 on 12 ; then an interval of 7-14, usually 9 or 10, joints between 

 successive syzygia. 



Eirst pinnule on the second distichal, quite small, little more 

 than half as long as and far more slender than those on the 

 second and third brachials, which are about equal. The next pair 

 are still larger, and the third pair (on 6th & 7th br.) still more 

 so, consisting of about 35 stout joints and reaching nearly 35 mm. 

 in length. That on the seventh joint is rather the smaller and 

 the next pair considerably so, only about equal to the first pair. 

 The diminution continues to about the seventh pair, which are 

 not specially small, being scarcely less than 10 mm. long. The 

 remaining pinnules are of about the same length, but gradually 

 become more slender. The basal joints of the lower pinnules 

 from the distichal pinnule onwards have rather sharp dorsal keels. 

 These may be less marked on the stout joints of the pinnules of 

 the second and third pairs, but reappear on the second and four 

 following joints in the fourth pair, and then gradually decrease in 

 distinctness, disappearing altogetlier by about the 25th joint. 



Disk naked and considerably incised, 15 mm. in diameter. 



Colour light brown. tSacculi closely set along the pinnule-am- 

 bulacra. Spread 20 centira.
