ing out opposite the eyes, then narrowing to near the antenne, where 
there is a slight constriction, and expanding slightly at the end, which 
is obtuselyrounded. Eyes very large, brown, wide apart, and sub-lateral, 
conneeted by a curved band of brown specks; antennie rather large and 
long, about one-third as long as the head. Tentacular cirri large, the two 
posterior much the longest, reaching to about the eighth setigerous seg- 
ment. Branchi of anterior segments broad oval or sub-circular, rounded 
at the end; posterior oves larger, broad oval, narrowed to the end. Pro- 
boscis with a large, swollen, basal portion, on which are twelve longi- 
tudinal rows of large, prominent, obtuse papillw, about seven in each 
row; anda terminal smooth portion, which is somewhat longer, and 
Bout as broad at the end as the basal pendant but considerably narrower 
at its commencement; the orifice is surrounded by a circle of large, 
rounded papillz. Color greenish, with a median dorsal row of dark 
brown spots, and another less conspicuous row along each side of the 
back, at the base of the lateral appendages.

The figure (56) copied from one of those given by Mr. Agassiz does 
not agree perfectly with the specimens described, but probably represents 
the same species. The head, as figured, is more oblong and the eyes 
nearer together than in my specimens; the tentacular cirri are less 
crowded. The-anterior ones, in the preserved specimens at least, appear 
to arise from beneath the base of the head. Some of these differences 
may be due to the different states of extension and contraction ; for the 
species in this family are all quite changeable in form during life, and 
usually contract very much in alcohol.

Head somewhat longer than broad, slightly cordate posteriorly, with 
the posterior angles well rounded, and the sides full and convex; front 
broadly rounded, and with a slight emargination in the middle. Eyes 
large, dark brown, placed on the dorsal surface of the head; antenne 
rather long, slender. Tentacular cirri long and slender, the two posterior 
much longer than the others. Branchiew of anterior segments broad 
ovate, with rounded tips; farther back larger and longer, ovate, leaf-like, 
with acuminate tips. Proboscis with twelve rows of papille on the 
basal portion, which are prominent, somewhat elongated, obtuse, seven 
or eight in the lateral rows, those in each row close together. Color of 
body and branchiie pale green, with a median dorsal row of dark brown 
spots, one to each segment; and two lateral rows, in which there is a 
spot at the base of each “ foot ;” head pale, or greenish white.
