general shape and the details of the corallum and every other 
structural peculiarity which can be observed on the specimens 
before me agree fully with St. diadema as do those of St. 
Moseleyanus. And as we do not possess satisfactory knowledge 
regarding the possible variations in the relations of the 
sclerosepta to each other in St. diadema (or in any other of 
the Stephanotrochus described as different species), I am 
inclined to doubt that St. diadema and St. Moseleyanus really 
are tenable as different species. The circumstance that a good 
many Atlantic animals, originally known from the Azores or 
still farther south, now have been shown to occur also in the 
northernmost part of the Atlantic, f. inst. at the Vestman Is- 
lands and upon the whole off the south coast of Iceland, where 
the conditions of temperature and bottom are almost the same 
as far south, makes it to me most probable that St. diadema 
and Moseleyanus will prove to be identical’). 
Stephanotr. diadema was first found by the “Challenger“, 
1873, off the Azores in 1009 Fathoms, later, 1888, by “l’Hiron- 
delle“ in the same region, in 1800—1557 M. Farther north 
it has been taken 1895, by the “Caudan“, in the Golfe de 
Gascogne, 1710 M. (46° 28' N, 7° W), South of Ireland by the 
“Thor“, 1905 (49° 25’ N, 12° 20 W, 1180—1270 M.), and by the 
Irish dredgings 1906—07 on 3 stations (between 51° 15’ and 
51° 35’ N, and 11° 4 to 12° Long. W), 695—720 Fathoms. 
On the American side it has been taken by the ,Challen- 
ger“ off Pernambuco, Brazil, 675 Fathoms, and by the ,Blake“ 
off Guadeloupe, 734 Fathoms, and in Lat. N. 19° 7’, Long. W

the two first only as varieties, the last as a young stage of one species:
