the lirst segment is very short, the 'second 

 third tli*- longest, about tour times as long as the 



as the third, but, the -listal end is tnon 

 panded distal end ; the following gradually deer 

 in |< ihimate is about as long as broad; the second and third segments 



ends considerablj enlarged, and are slender and broadly 



lurth has the proximal end only very slightlj enlarged, but gra- 



the distal edge, which is produced and overlaps the base 



nent; the following segments gradually increase in lateral diameter, the 



radually decreasing in extent; the fifth and following segments 



ninal tubercles; the opposing spine is terminal, minute, but larger than the 



the preceding segment; the terminal claw is nearly twice as long as the penulti- 



and is ly curved. 



I in the median line, but are slightly visible in the angles of 

 the IBr, are very short, oblong, live or six times as broad as long, very closely 

 1 with the ling axillary, which is triangular, twice as broad as long 



arms are 45 mm. long; the brachials resemble those of C. hispida. The ossi 

 livision series and the brachials have their distal borders armed with very long fine 

 spines; the segments of the pinnules are exceedingly spinous and the third has a slight, very 

 spino rination. 



second specimen is smaller, but otherwise resembles the one described.

The largest of the six specimens from Stat. 266 has the arms 40 mm. long; the cirri 



Il lost . 



The larger example from Stat. 267 has been chosen as the type; the centrodorsal is 



1 lal, with a broad flat dorsal pole 2. mm. in diameter; the < irrus sockets are arran- 



very closely crowded marginal row. 



The cirri are lacking; but in the smaller specimen the cirri are XX. in one and a 



part; id row. the latter apparently undergoing suppression; there are also traces of the 



third row. The cirri have 9 segments and are from 4 mm. to 4.5 mm. long; the 



irly or quite twice as broad as long, the second is slightly longer than 



third is about three times as long as the diameter of the proximal end, the fourth 



;htl\ rid the fifth is about as long as the third; the sixth is about twice as long 



istal end; the seventh is slightly shorter; the antepenultimate is half 

 tnd the penultimate is about as long as broad. The longer earlier
