The species Stephanotr. Moseleyanus is established by Sclater 
on a single specimen taken by the "Triton" 1882 in Lat. 59° 
51’ N, Long. 8° 18' W, 570 Fathoms, 7° 7 C; this locality is 
about halfway between the Færøes and the Hebrides. From 
the same part of the North Atlantic, only farther north, is the 
above station of “Michael Sars“; I think there can be but 
little doubt as to the specific identity of Sclater’s specimen 
with that of “Michael Sars“ and as well with some specimens 
in the Copenhagen Museum taken farther west by the “Thor, 
viz south of Iceland (62° 57’ N, 19° 58’ W, 957 M.) and by the 
- *Ingolf*, southwest of Cape Reykianes (62° 58’ N, 23° 28’ W, 
486 Fathoms, 5°5 C; and 61° 44' N, 27’ W, 485 Fathoms, 6°1 C). 
All these specimens are still covered with the soft tissues of 
the animal, and as I, for the present at least, do not wish to 
destroy any part of the tissues, I have not been able to decide, 
if only the quaternary sclerosepta join the tertiarics in the 
way said by Sclater to be characteristic for the species Mose- 
leyanus and to distinguish the latter from St. diadema. The
