1903. ] IN THE ‘ CHALLENGER’ COLLECTION, 59 
opinion. The investigation of the material preserved in the 
British Museum proved the correctness of my disbelief, but, it 
must be admitted, to a degree not supposed. 
Of the specimens enumerated by Bate, the following have not 
been preserved in the British Museum: “ Stat. 42, lat. 35°58’ N., 
long. 70° 35' W., 2425 fathoms,” “length 25 mm.”—and “On 
May 6-18th, 1876, in lat. 32° 41’ N., long. 36° 6’ W... one 
specimen ... at the surface; and on the 7th of the same month, 
near the Azores....two other specimens were taken at the 
surface.” I can now state with certainty that if the specimen 
from Stat. 42 lived near the bottom in that enormous depth, it 
did not belong to S. atlanticus; perhaps it was captured near the 
surface, but at all events the locality must be omitted as uncertain. 
Most probably the specimens captured in May 1876 belonged to 
S. atlanticus. The specimens from the other stations enumerated 
by Bate belong to four species, and each station must be mentioned 
separately, 
“North Atlantic .... Stations 62 and 63, on the passage from 
Bermuda to the Azores. Three specimens.” In a bottle labelled 
“ Between Bermudas and Azores” I found eight partly mutilated 
specimens of S. atlanticus. 
“Between Teneriffe and St. Thomas.” In a bottle with the 
same locality, three specimens of S. atlanticus. 
“Station 320,.... lat. 37° 17'S., long. 53° 52’ W., off Monte 
Video; depth 600 fathoms.” Bate does not directly state the 
number of specimens, but he writes ‘‘ Length 38 mm.,” and the 
meaning is probably that he had one single specimen. Ina bottle 
labelled “ off Monte Video” I found six small and badly preserved 
specimens of S. atlanticus M.-Edw., and one large specimen of 
S. arcticus Ky., and it is decidedly the last-named specimen which 
was procured from 600 fathoms. As to S. arcticus Ky., the 
student is referred to Kréyer’s work, to the description and 
drawings in various papers of 8. Smith, to notes in my earlier 
paper, and to some remarks below, in the description of S. similis, 
n. sp., together with figs. 1 a—c on Pl. XII. 
“Station 159, ... south of Australia ; depth 2150 fathoms. ... 
Three specimens... Length 43 mm.” In the collection three 
large specimens are present, but they belong to S. arcticus Kr., 
which thus has been proved to be distributed through the deeper 
Atlantic, from the southern part of Greenland to lat. 38° 8., and 
to south of Australia. 
Bate enumerates still two deep-water stations, viz. Stat. 252, 
off Japan, and Stat. 173, off Matuku, Fiji Islands; he examined 
one specimen from each of these localities, but the animals belong 
to two new species to be described below. 
But before giving these descriptions I will sum up the results 
of the examination of the specimens referred by Bate to S. atlan- 
ticus H. Milne-Edw. (=S. fristi Kr.). The Copenhagen Museum 
possesses some hundreds of adult specimens of S. atlanticus, taken 
at a large number of places in the Atlantic, the Indian Ocean,
