All of the specimens from Stat. 89 are small. One has 15 arms 40 mm. long: the cirri 

 have 17 segments of which the proximal are proportionately more slender than in adults-, P„ 

 is proportionately more slender than in the adults, with to segments, which are proportionately 

 longer, and is slightly recurved; P resembles the following pinnules. Another has 20 arms 

 70 mm. long; the cirri are about [6 mm. long with 19 segments; P, is 8 mm. long with it 

 segnv-nts; P resembles P r A third has iS arms 65 mm. long; the cirri are 15 mm. long with 

 19 segments; I', is 9 mm. long with 11 segments. Of the remaining specimens three have is 

 arms and tour have 14 arms; in one of the latter P., has 12 segments. One individual not 

 enumerated above is small and much broken. 



The example from Stat. 96 has 17 arms. and is undergoing adolescent autotomy; P, 

 segments of which the first two are about as long as broad and the third is twice as 

 broad.
