Döderlein. According to Ludwig (Op. cit. p. 465) it is only 

 a form of S. endeca ; 1 cannot feel sure of that and think that 

 Döderlein is right in regarding it as a distinct species. But 

 whether species or variety, as it is easily recognised, it must 

 at all events be treated separately from the typical S. endeca.

Jan Mayen, 55 fathoms, 13 specimens (one 9-armed, one 

 13-armed, the others with 10 arms). — Кар Tobin, 57 fath., 1 

 sp. — Turner Sund. 120 fath., 1 sp. 



One 10-armed specimen from Angmagsahk, 1 40 fathoms, differs 

 from the typical form in having 5 — 6 adambulacral spines, the 

 adorai one mostly smaller than the others, and in the abactinal 

 skeleton forming rather small meshes; the papulæ are disposed 

 singly, seldom 2 — 3 together in one mesh. The paxillae are rather 

 small and closeset, the thorns not truncated. This, rather 

 badly preserved, specimen undoubtedly is nearly related to the 

 Var. septentriotialis Sladen (« Challenger» -Asteroidea p. 445); 

 however, it does not agree so exactly with the description, that 

 it can be definitively referred to that variety. 



Three specimens from Hurry Inlet, 50 fathoms, may be referred 

 to the var. squamata Döderlein. (Op. cit. p. 208). They agree with 

 this form in the curious, scalelike, abactinal skeleton (PI. II. 

 Fig. 6) and in the number of adambulacral and external spines. 

 *The paxillae of the abactinal side are rather closeset, uniform, 

 long and slender, with about 3 — 10 spines, mostly 4 — 6, disposed 

 in a single circle and all of the same length (about 1,5 mm.). 

 This form looks very different from the typical S. papposus, in 

 which small and large paxillae are found together. All the three 

 specimens have 11 arms. R. = 2V4 r. 



This very curious form might well be separated from pap-
