S. atlanticum Southward and Southward, 
1958, from the northeastern Atlantic, in 600- 
1400 m. 
S. inermis Southward and Southward, 1958, 
from the same locality as the preceding. 
S. veleronis, n. sp., from La Jolla canyon, 
southern California, in 976 m. 
In addition to S. veleronis, the collections of 
the Allan Hancock Foundation contain repre- 
sentatives of three other pogonophores. One is 
mentioned earlier (Hartman and Barnard, I960: 
283) coming from West Cortes, East Cortes, 
and Long basins and from the San Diego trench. 
The collar segments of the tube measure 2.9 
mm. across and 3.3 mm. long; each is drab dark 
brown, cylindrical, paler at one end where it 
flares and is frayed. In size and shape they most 
nearly resemble those shown for Galath ealinum 
(Kirkegaard, 1956: 81). 
Another kind, a Siboglinum sp., has just been 
received from a trawl station, "Velero IV,” sta. 
7231, off San Eugenio Pt., Lower California, 
Mexico, in 4800 m. This organism inhabits 
tubes which, in size and color, resemble those 
of S. veleronis, but the alternating brown bands 
are single, not double, and range from four to 
six times as long as the pale ones, or only a lit- 
tle longer. The protostoma has a pair of small 
red eyespots at the sides — the first known in- 
stance of eyes in pogonophores. The ventral side 
of the tentacle appears villous, due to paired 
rows of long, closely set pinnules. The uncini 
are in two transverse, single rows and are set 
far apart, the distance being about equal to four 
times that of the body width. 
A fourth species is S. ekmani Jagersten, from 
the Skagerack, Denmark, a gift from the Zoo- 
logical Museum at Copenhagen.
