The first unquestionable mention of this species is that of Quoy and 
Gaimard, 1824, in the Zovlogy of Freycinet’s Voyage, I., 198, at the 
end of their description of Seymnus bispinatus. “Un autre trés-petit 
individu femelle, pris par nous au Brésil, et nommé Scymnus brasiliensis 
par M, Cuvier, a & peu pres la forme du précédent; mais il se fait remar- 
quer par la grosseur démesurée de sa machoire inférieure, par sa gueule 
plus rapprochée de lextrémité de son museau, par la largeur plus grande 
de ses nageoires dorsales, et par labsence d’aiguillon aux ventrales. Les 
deux lobes de la caudale sont aussi plus profondément divisées. Enfin, 
sa couleur est d'un brun plus clair, et on remarque une large bande 
d'un brun foncé sous la gorge.’ In 1840, F. D. Bennett notes the 
occurrence of the genus in Lat. 2” 30’ South, Lon. 163° West, a ten-inch 
specimen captured in a tow-net af the surface, and again in “Lat. 65° 
North, Lon. 110 West,’ an eighteen inch specimen. Bennett’s longitude 
is incorrect; it probably was 140° W. Miiller and Henle, 1841, give 
Isle de France, St. Jago, and Rio de Janeiro as the localities of the 
specimens examined by them. G. Bennett, 1860, reports on a five and 
one half inch individual from Lat. 2° 15’ South, Lon. 163° West. Kner, 
1864, gives the locality “ Australia” for a seven inch specimen studied 
by himself. Dumeril, 1865, records one from Mauritius of more than 
nineteen and one-half inches, the largest yet recorded. Giinther, 1870, 
had a ten inch specimen from the South Pacific and a six inch specimen 
from the Gulf of Guinea. Peters, 1876, had one from Lat. 14° 23’ 07” 
South, Lon. 118° 16’ 03” East, in the Indian Ocean. The “ Albatross” 
collection adds a locality near the Galapagos Islands, station 3413, Lat. 
2° 84’ North, Lon. 92° 06° West. The depth given for this station is 
1360 fathoms. In the same haul Bathytroctes and other undoubted deep 
sea forms were taken. The large eyes and the phosphorescence of Isistius 
certainly would not be out of place at very great depths; yet in view 
of the fact that all of the captures previously noted were from the surface 
or from depths much nearer to it than that reported by the “ Albatross,” 
and of the fact also that the trawl was open on its way up, there 
is still some uncertainty as to whether this shark descends so far.
