THE POLYOHfiETOUS ANNELIDS OF PORTO RICO.

from here it narrows again rapidly; thirty-second segment, 5 mm. wide. Color above, seal-brown, 
shading into ashy gray anteriorly; ventrally, ashy gray. Setae long, very fine, white. Caruncle 
small, smooth, not extending beyond limits of head lobe. .Dorsal setae shorter than ventral. Dorsal 
cirrus arising at base of tuft of setae, a little behind and ventral to them. Cirrus about three-fourths 
as long as setae. Ventral ramus with a thick fleshy lip, from the dorsal edge of which the setae arise. 
Ventral cirrus slender, shorter than lip of ramus. Two tentacles and two subtentacles present, the 
median tentacle having been lost. (See fig. 32.) No eyes could be seen. Mouth surrounded by two 
segments, the posterior lip lying in the interruption of median 
line of third segment. Gills appear first on eighth segment, as 
a single filament, attaining their full size about segment 12. 
They are very inconspicuous, lying behind the dorsal cirrus, 
and in preserved material almost completely hidden in the con- 
striction between the segments. In its fully developed form 
each gill is composed of a tuft of thick, short filaments. 
In the generic description of Amphinome (Kinberg; Sven- 
ska. Vetensk. Akad. Ofversigt, vol. 14, pp- 11 to 14, 1858) it is 
stated that the gills begin on segment 3. In the absence of a 
median tentacle and in the fact that the gills appear first on the ninth segment, this specimen differs 
from the generic diagnosis. I have regarded the former as an accident, and the latter as not of suffi- 
cient importance on which to form a new genus.

A number of fragments, lacking both head and tail, seem undoubtedly to belong to this species, 
though the remaining parts differ somewhat from Webster’s description. Dorsal and ventral rami of 
parapodia separated rather more widely than in Webster’s description. Terminal portion of ventral 
ramus expanded at base and narrowing rapidly toward apex. Webster figures it as slender and 
conical. Dorsal ramus as in Webster’s description. Dorsal palese in a row extending across back, the 
median ones bending inward, so that those of opposite sides overlap. Set* of two kinds. Those of 
dorsal ramus constricted at base, like dorsal pale*, and for inner two-thirds of their length marked 
with the longitudinal and transverse striations characteristic of latter. These are figured by Webster 
as smooth, with sharp point and broad base. 
The set* of the dorsal ramus are regarded by Johnson (Proc. Calif. Acad. Sci., vol. 1, No. 5, 
p. 162) as a second form of pale*, and are one of the characters of his new genus Heteropale. The data 
in my possession are few, but from what I have I am inclined to believe that Johnson’s Heteropale, 
should be discarded in favor of Schmarda’s Bhawania. In the shape and position of the other set*, 
these specimens agree with B. goodei. 
Ehlers (Annelids of the Blake, p. 34) describes fragments of a Chrysapetallid in which the pale* 
cover the back. He does not describe any other details.

Eunice ornata Andrews, Annelida Polychseta of Beaufort, N. C., Proc. U. S. Nat. Mus., vol. 14, p. 284, 1891. 
Collected from stations 6080, 6079, 6073, 6092; Mayaguez; Ponce; stations 6086, 6091; and 
a female with eggs from Arroyo. In the specimen from station 6092 the gills began on the sixth seg- 
ment, instead of the fifth, which, according to Andrews, is the normal.
