earlier in the season, for its eggs were found attached to alge and eel- 
grass at the date named. The eggs of this species are small, yellowish 
white, imbedded in a gelatinous mass, having an annular form, but 
showing a break or suture on one side. These annular egg-inasses are 
attached by one side to the surfaces of flat alge or eel-grass in large 
numbers; they are from .12 to .20 of an inch in diameter. 
The Aolis papillosa was found at Watch Hill, under stones, April 
12, and with it were long, much convoluted, gelatinous cords, filled with 
minute pale red or salmon-colored eggs, which probably belong to this 
species, which is a northern one, and has not hitherto been recorded as 
from south of Cape Cod. Itis very abundant in the Bay of Fundy, and 
similar egg-clusters are found there under rocks during the entire suin- 
mer. 
Among and between the stones the northern purple star-fish, Asterias 
vulgaris (p. 432) is often found at low-water, and also the green sea- 
urchin, Strongylocentrotus Drébachiensis (p. 406, Plate XX XV, fig. 268) 
during the spring tides. 
The Balanus balanoides (p. 305) is quite as abundant on the most ex- 
posed rocks as elsewhere. The minute bivalve young of this species 
were found just attaching theinselves to the lower surfaces of rocks in 
immense numbers at Watch Hill on the 12th of April. 
Beneath the stones the rock-crab, Cancer irroratus, (p. 312,) is very 
common, and occasionally the much rarer Cancer borealis is found dead 
on these shores. It was thus found at Gay Head and No Man’s Land, 
but it is doubtful whether it lives above low-water mark. In the 
Yower part of the fucus zone the large Gammarus ornatus (p. 314, Plate 
IV, fig. 15) is always to be found in great abundance uuder stones, and 
in the upper half of the fucus zone the smaller species, Gammarus an- 
nulatas (p. 314) and Gammarus marinus often occur in great numbers, 
associated with Jera copiosa (p. 315) and Idotea irrorata (p. 316, Plate 
V, fig. 23.) The Gammarus marinus occurs higher up than either of 
the other species, and is sometimes abundant even near high-water 
mark, where the soil beneath the stones is barely moist at low-water. 
The Amphithoé maculata (p. 315, Plate LV, fig. 16) is also a common 
species under stones; and both green and reddish brown varieties 
occur. 
Another species of Amphithoé, of smaller size, was found swimming 
free in the rocky pools at Watch Hill, April12. In this the general color 
was red, or brownish red; the body was transversely banded with pale 
flesh-color or whitish, alternating with bands of dark red or brown, which 
are made up of minute crowded specks; the antenne are annulated with 
pale red, and are thickly specked, on the bands and at the base, with 
darker red. The Hyale littoralis (p. 315) is a small but very active Am- 
phipod, which is often abundant near high-water mark on the rocky 
shores, clinging to the Fucus and other alge, or swimming in the tide- 
pools. It is capable of leaping actively like the beach-fleas, (Orchestia
