Durine the summer of 1877, extensive explorations were 
made by the U. S. Fish Commission in the U. S. Steamer 
“Speedwell,” Commander Kellogg, in Massachusetts Bay ; in 
the Gulf of Maine; off Nova Scotia; and in the vicinity of Hal- . 
ifax. e dredging and trawling were very successful, and a 
large and valuable collection was secured, both of fishes and 
invertebrata, including, in all classes, many European and 
Greenlandic forms not before obtained on the American coast. 
s in es years the invertebrate collections and the direc- 
Mo.uvsca. 
Architeuthis megaptera Verrill, sp. nov. 
Much smaller than the previously known species, the total 
length of the body and head being but nineteen inches. Body 
relatively short and thick. Caudal fin more than twice as broad 
as long, the length about half that of the body. Its form is 
nearly rhombic, with the lateral angles produced and rounded, 
and the posterior angle very obtuse, the posterior edge, as pre- 
served, being slightly concave. The ventral anterior edge of 
the mantle is concave centrally, with a slight angle to either 
side, about -75 inch from the center; from these angles it is 
again concave to the sides; on the dorsal side the edge advances 
farther forward than beneath, terminating in a slightly prom- 
Inent obtuse angle in the middle of the dorsal edge. The eye- 
Sockets are large, oblong, and furnished with distinct lid-like 
margins; the eyes are large, oblong, and naked. shor 
arms are triquetral, the upper ones somewhat shorter and smaller 
than the others, which are nearly equal in length, the second 
pair being stouter than the rest, and a little longer. The ten- 
tacular arms are slender, elongated, expanded toward the tip, 
and have suckers arranged much as in the gigantic species, even 
to the smooth-edged suckers and opposing tubercles, proximal to 
the large suckers, as I have formerly described them in A. 
monachus. The sucker-bearing portion is margined by a mem- 
brane on each side.
