larity either in correspondence of height or in continuous 
extent, and no single section would embrace all of the eight 
distinct and pasted terraces which were noted on each side of 
the river. 
It is mainly sides of sand, nearly level, but with a slight 
slope to the west and south, being as usual towards the river 
and in the direction of its course. Its northern portion changes 
to gravel which becomes coarse on the southeast side of 
Wantastiquit Mountain, containing pebbles one foot or some- 
times a foot and a half in diameter. The position and slope o 
this plain show that it was not deposited wholly from currents 
of the main valley, but that a considerable portion was con- 
tributed from the melting of the ice-sheet east of this mountain.

AMONG the mers ee discoveries made during the 
pegs ae summer by the United States Fish Commission (Prof. 
F. si, Donemsiiontn) is ger of a species of Macrurus 
believed a ‘be undescribed. As ngle specimen was taken in 
rawl net, August 19, 1877, on the + voyage of the U.S. Steamer 
“ Speedwell” from Salem to Halifax. It was found in the 
Gulf of Maine, forty-four miles from Cape Ann (east $ south) 
in 160 fathoms, muddy bottom (locality 35). Two members 
of this family ee included by Professor Gill in his Catalogue of 
the Fishes of the East Coast of North America (Washington, 
1873). One, Coryphenoides norvegicus, has been recorded only 
from Grasnlands a and the northern and western coasts of Nor- 
way. The other, Macrurus rupestris, has ave the same geo- 
graphical range: a fish found floating at sea near Gra vesend, 
N. Y., in 1876, and now in the U. 8 Na Ganal Museum, has 
been identified with this species. 
The genus Macrurus, auct., has been subdivided into three, 
viz: Macrurus, Coryphienoides and Malacocephalus. The most 
important diagnostic character eran. by Dr. Giinther as sepa-
