slenderer and a little longer but are never conspicuous; also, branchiae 
are longer but continue to be simple, cirriform. The pygidium is 
surrounded by about 20 papillae. 
Webster described interparapodial eye spots, present from the 
seventh segment, numbering 11 pairs; hence this is an Armandia. 
These spots are not visible now. A. maculata is known only through 
its original discovery.

Genus OPHELIA Savigny 
OPHELIA LIMACINA (Rathke) 
Ammotrypane limacina RATHKE, 1848, pp. 190-192, 202-205, pl. 10, figs. 4-8. 
Ophelia denticulata VERRILL, 1875, p. 389; 1882, pl. 9, fig. 3 (U.S.N.M. No. 16128; 
off Block Island, R. I., in 14 fathoms). 
Ophelia limacina FAUVEL, 1927, p. 182, fig. 46. 
The type of O. denticulata is labeled “Off Block Island, 14 fms. 
Aug. 18, 1874. P. M. 856 figs.” Branchiae were described as denticu- 
late; hence tke specific name. Since, however, these denticulations 
are perhaps merely wrinkles of contraction, they are not significant. 
There are 9 anterior setigerous segments, lacking branchiae; this 
is followed by 18 branchial segments and 5 postbranchial segments, 
a total of 32 setigers. The anal ring is provided with 16-18 smaller 
papillae and 2 larger, lanceolate cirri ventrally. 
This agrees fully with O. limacina (Rathke), already reported from 
eastern America by Webster and Benedict (1884, p. 724) and others.
