as long as wide, and distally rounded, though asymmetrical. They 
increase rapidly in width posteriorly and are broadly imbricated. 
This species was collected many times by the author in oyster 
clusters at Beaufort, N. C. In life it is bright green; it is gregarious, 
with a tendency to mass together in interstices of oyster clumps. 
In spite of numerous attempts to incite the protrusion of the pro- 
boscis in life, no success was obtained. Examinations of dissections 
revealed only a slender, wrinkled tube. 
Genus EUMIDA Malmgren 
EUMIDA SANGUINEA (@rsted) 
Figure 8, f, g 
Eulalia sanguinea ORstTep, 1848, p. 28, figs. 80, 82. 
Eulalia maculosa WEBSTER, 1879, p. 215 (U. S. N. M. No. 498; Great Egg Harbor, 
N: 32): 
In the type of Hulalia maculosa the proboscis is smooth; hence 
this is a Humida. It terminates distally in 17 soft papillae. The 
median prostomial antenna is inserted a short distance anterior to 
the large, dark, paired eyes. The longest tentacular cirri extend 
posteriorly to about the tenth setiger. Dorsal cirri are thin, folia- 
ceous, longer than broad, but increase in length posteriorly; these 
parts are shown in figure 8, f, g, for median and posterior parapodia. 
This agrees well with the widely known £. sanguinea, already 
reported from many parts of the north Atlantic and Pacific.

Eumidia vivida VeEBRILL, 1873, p. 584 (U.S.N.M. No. 10159; Vineyard Sound, 
Mass.). 
Eulalia viridis FAuvet, 1923, p. 160. 
The type collection of Zumidia vivida includes about 12 specimens. 
The everted proboscis is cylindrical, covered over its entire length 
with irregularly dispersed papillae or forming seven or eight irregu- 
lar, longitudinal rows. The first tentacular segment is dorsally en- 
tire, as typical of the genus Fwdalia. The median prostomial antenna 
is inserted a short distance anterior to the eyes. Dorsal and ventral 
cirri and parapodial lobes have the proportions shown in figure 
9, a, 6. These are typical representatives of Fudalia viridis (O. F. 
Miller).
