 Enkhuizen Island, near Batavia, Java. 1 Ex. 



The individual from Stat. 43 has 35 arms about 120 mm. long, and cirri XIV, 26 — 

 27, 25 mm. long. 



This specimen may almost equally well be referred to nigra or to stclligera ; 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, 25 mm. long.
