IDENTITY OF SOME MARINE ANNELIDS—HARTMAN 129 
These specimens are not to be distinguished from A. aulogaster 
Rathke, already known from eastern North America (Webster and 
Benedict, 1887, p. 727). 
Genus ARMANDIA Filippi 
ARMANDIA AGILIS (Andrews) 
Figure 12, c, d 
Ophelina agilis ANDREWS, 1891, p. 289 (U.S.N.M. No. 4898; Beaufort, N. C.). 
The collection includes three specimens; two are posteriorly incom- 
plete. Interparapodial eye spots are present between segments 6/7, 
8/9, * * * 16/17, 18/19, or 11 pairs; this is therefore a repre- 
sentative of Armandia. Setigers number 52. Branchiae are present 
from the second segment; they are long, cirriform, present on all 
other segments to the end; on their dorsal side, near the base, they 
have a thin, foliaceous flange (fig. 12, d). 
On the first segment the upper presetal lobe (dorsal cirrus) is 
large and long, resembling a branchia except for its smaller size (it 
is about two-thirds as large); this gradually diminishes in size 
posteriorly so that in the posterior third of the body it is greatly 
reduced, papillar (fig. 12, d). The lower, postsetal lobe (ventral 
cirrus) is a minute, translucent, subglobular structure throughout 
(fig. 12, c, d). Setae are simple, flowing, capillary. The caudal 
funnel is long, compressed cylindrical, closed ventrally along a pair 
of longitudinal ridges, provided at its distal end with about 14 
filiform cirri, and a much longer, thicker, ventral cirrus. 
Armandia agilis differs from other species of the genus in its high 
setigerous count, in the structures of the presetal and postsetal lobes, 
and the closed anal funnel. It is known only from North Carolina. 
ARMANDIA MACULATA (Webster) 
FicureE 14, a 
Ophelina maculata WessteER, 1884, p. 322 (U.S.N.M. No. 4796; Bermuda). 
The collection includes two specimens. There are 29 setigers [27 
or 28 according to Webster]. Branchiae are present from the second, 
perhaps nearly to the end or at least to the third last segment; the 
posterior segments are now macerated, imperfect. The prostomium 
is thick, about as broad as long, but with a long, slender anterior 
cone nearly as long as the main part of the prostomium. Eyes 
cannot now be distinguished, but Webster (1884) described three, 
in a transverse series, near the posterior margin of the lobe. 
Presetal and postsetal parapodial lobes are short, though broad, 
throughout, not unusual in any respect. A second has the proportions 
shown in figure 14, a. More posteriorly the postsetal lobes become
