200 REPORT OF COMMISSIONER OF FISH AND FISHERIES. [494] 
transverse dorsal band of red or orange on each segment, and similar 
ones on the epimera, and were minutely specked with dark brown; the 
antennze and legs were annulated with white and light red or orange. 
Another species of Podocerus was still more abundant among the red 
alge; in this the males and females differ greatly in size, form, and color. 
The females are much smaller and stouter than the males; their colors 
were generally red and white,in strong contrast,though some were pur- 
plish and more like the males in color; most of the females have the 
head and few anterior segments dark red; then a band of white; then 
three or four bands of dark red, on the middle of the body, which are 
often confluent into a large dorsal spot of red or brown; these are fol- 
lowed by a broad white band or spot; the abdominal rings are alternately 
banded with red and white; part of the epimera are red. The antenne 
and legs are more or less annulated and spotted with red. The eyes are 
black. In the male the color is generally reddish or purplish brown, 
but irregularly specked with darker brown, and with the intervals 
between the segments pale red. 
Species of Caprella occur in considerable numbers, clinging, in gro- 
tesque attitudes, upon the delicate alge and hydroids. The Idotea 
érrorata, (p. 316, Plate V, fig. 23,) isalso very common, living among the 
alge, and Frichsonia filiformis (p. 316, Plate VI, fig. 26,) is often associ- 
ated with it. 
The Annelids living upon such bottoms are difficult to obtain, since 
they mostly burrow beneath the stones or live in tubes attached to the 
rocks. The few species obtained are, with few exceptions, not different 
from those found in the sounds, on similar bottoms. The Autolytus cor- 
nutus, (p.397, Plate XIII, figs. 65, 66,) and another species of the sane 
genus were found in abundance, living in tubes attached to the fronds 
of Laminaria among hydroids, (Obelia geniculata.) On the same fronds 
were long, crooked tubes, formed of grains of sand and small bits of 
shells, belonging to Nicolea simplex, (p. 397.) 
Burrowing in the corals of Astrangia Dane we found, on the reef off 
Watch Hill,the singular Annelid named Naraganseta coralii by Dr. Leidy, 
who obtained his specimens at Point Judith. The specimens found by 
us were mostly very dark greenish brown or black, but some had dark, 
orange-colored branchie. The Lepidonotus angustus, Phyllodoce gracilis, 
P. catenula, and Humidia Americana are new and interesting species. 
Nereis fucata occurs rarely. 
Of Gastropods many species already enumerated as inhabitants of 
the rocky shores occur also on the rocky bottoms in abundance, but there 
are a number of additional species. One of the largest is the “ whelk,” 
Buceinum undatum, (Plate XI, fig. 121.) This is a decidedly northern 
and arctic shell, found also on all the northern coasts of Europe, though 
several authors believe that the American and European shells are dis- 
tinct species. 
One of the most interesting-of the northern shells that occur here is
