The individual from Stat. 43 has 35 arms about 120 mm. long, and cirri XI\', 26 — 
27, 25 mm. long. 
This specimen may almost equally well be referred to nio;ra or to stclligcra ; in its 
habitus and in the details of its arm and cirrus structure it is intermediate between the two. 
The specimen from Stat. 99 is small, but typical ; it has about 65 arms which are 
about 100 mm. long, and cirri XVII, 27 — 32, moderately stout, 25 mm. to 28 mm. long. 
The example from Stat. 282 has about 70 arms; the cirri are robust, 30 mm. long, 
composed of 23 — 25 segments. 
The specimen from Enkhuizen Island has about 60 arms; there may be as many as 
five axillaries exteriorly; there are usually three interiorly; the cirri are XXXVIII, 23 — 26, 
large and robust, 2s mm. long.
