animal their length is about twice their width. The ventral cirri 
are oval and slightly longer than the parapodia. In the type specimen, 
the number of setae per parapodium is about 10, and in the second 
fragment it is about 15. The ends of the shafts of the setae are 6u-7y 
thick and have large fangs with a few secondary teeth (fig. 29). 
The blades are very short (20u—25y). Anal cirri were lost. 
The color of the animals is pale greenish with marked black pig- 
ment bands dorsally on the posterior margin of each segment. 
The name refers to the noticeably short blades of the setae. 
Diacnosis.—A small Pterocirrus species with an oval prostomium, 
small eyes, and a long unpaired antenna. Clavate papillae on proboscis. 
First segment dorsally reduced. Shafts of setae with large fangs and 
very short blades. 
DIFFERENTIAL DIAGNOSIS.—The species belongs to the subgenus 
Pterocirrus Claparéde of Eulalia, as defined by Banse (1959; see also 
Day, 1960). It is distinguished from the type-species, E. (Pterocirrus) 
macroceros (Grube) (cf. Banse, 1959), by the oval shape of the pros- 
tomium, the small size of the eyes, the clavate papillae on the proboscis, 
the toothed tips of the shafts, and the short blades of the setae. 
Possibly also H. marginata Claparéde (see Rullier, 1964) belongs to 
Pterocirrus as defined now, although Claparéde (1868) stated that all 
cirrophores of the second and third segments are supported by aciculae. 
The new species differs from EH. marginata in this character, the small 
eyes, the toothed ends of the shafts, and the short blades of the setae.

There is one broken specimen, presumably a mature male, from 
station 2, August 1963. The animal is at least 25 mm long and about 
0.75 mm broad (without parapodia). It is particularly distinguished 
by the proximal papillae of the proboscis, which form seven or eight 
fairly irregular rows of about nine round papillae each on both sides. 
The papillae leave broad mid-dorsal and midventral gaps, the dorsal 
one tending to be V-shaped. Because of its broad base, the shape of 
the dorsal gap is not nearly as regular as shown by Rioja (1941, pl. 1: 
fig. 2). There is a tiny nuchal papilla. Only the ventral tentacular 
cirri of the second segment are left, which are filiform and three- 
fourths as long as the body is wide. Setae start on the third tentacular 
segment. 
The parapodia have large supra-acicular lips (fig. 3a). Cirri are 
preserved only in median-posterior segments. There are about a dozen 
setae per parapodium. Their shafts end in numerous small teeth; the
