10 IOWA STUDIES IN NATURAL HISTORY 
Eulalia foliosa new species 
A single imperfect specimen, probably collected at Station 101. The 
length is approximately 22 mm., the greatest width about 1 mm. 
In the preserved material the dorsal surface of the anterior somites is 
very dark brown in color, with a narrow colorless band on either side 
just dorsal to the parapodium. At the posterior end this color disappears. 
The prostomium (figure 16) is nearly circular in outline and has a pair 
of enormous eyes. The median tentacle arises between the eyes, is slender 
and about as long as the prostomium. The frontal tentacles are heavier 
than the median and are about as long as the prostomium. Only one 
tentacular cirrus remains and this is enormously broadened at the base, 
much flattened and curved backward lateral to the first somites. 
A parapodium from the middle of the body (figure 17) is long and 
slender with a bifid presetal lobe of which the dorsal lip is the longer. 
There is a single acicula reaching the surface between the lips of the 
presetal lobes, and a ventral tuft of sete. The only dorsal parapodial 
lobes remaining on the specimen are on the next to the last somite. They 
are slender-lanceolate in outline. The seta shafts are slender and oblique- 
ly truncated at the apex. Into the truncated portion fits the base of the 
terminal joint which is very slender, curves rapidly to an acute tip and 
is denticulated along one border. (Figure 18) 
The type is in the Museum of the State University of Iowa. 
Family Syllide 
TyposyLuis Langerhans 
Typosyllis corallicola Verrill 
Typosyllis corallicola Verrill, (1900), p. 603. 
Two incomplete specimens collected at Pelican Island seem to 
belong to this species, though the greenish pigment cells which 
Verrill described on the cirri were not to be seen, and the 
cesophagus extended over 8 somites instead of 10 to 12, as in 
Verrill’s material. 
TRYPANOSYLLIS Claparéde 
Trypanosyllis vittigera Ehlers 
Trypanosyllis vittigera Ehlers, (1887), p. 151, pl. 40, figs. 1 to 3. 
A fragment of the posterior end of a syllid was collected at 
Station 101 and it is probably of this species, though im the 
absence of the anterior end it is not possible to be certain on 
this point. 
HapLosy.tuis Langerhans 
Haplosyllis cephalata Verrill 
Haplosyllis cephalata Verrill, (1900), pp. 613, 614. 
A large number collected in sponges at Falmouth, Antigua. 
The sete showed decided tendencies toward a bifureated apex.
