BARBADOS-ANTIGUA REPORTS 21 
several patches of darker filaments giving the gills a beaded appearance. 
On either side of each rachis extending not much beyond the middle of 
its length is a row of minute eye-spots. 
The collar is very narrow with ends separated dorsally but ventrally 
they are nearly in contact. The ventral recurved flaps are bluntly trian- 
gular in outline and their tips extend only to about the posterior margin 
of the collar. 
The body is too badly mutilated to allow of accurate description. On 
the right side of the thorax are seven rows of sete and on the left only 
six. 
In the dorsal tuft are two kinds of thoracic sete. The longer (figure 
30) extend for about one-third of their length beyond the shorter. Each 
has a central axis which is curved and sharp pointed at the apex with a 
marginal wing which is very broad at the bend, wider on the convex side 
and tapering to a very acute point. Ventral to these is a double row of 
paleiform sete each (figure 31) with a very heavy stalk and a wing, 
forming when seen in full face a circular expansion entirely around the 
end. In profile the central axis is seen to bend slightly at the end and 
the expansion appears as a flat plate. 
Ventral to these set® lies a row of uncini with pennoned sete at their 
bases. The uncini (figure 33) have a single large tooth and a very 
heavy base, with on the crest fine striations but nothing that could proper- 
ly be called denticles. The pennoned seta (figure 32) has the head 
noticeably striated and a very fine point. 
The abdominal sete are of two kinds, both only slightly modified from 
those found in the thorax. The palee are quite similar to those of the 
thorax and the others resemble the pointed ones found in the thorax but 
are more slender with very long slender, sharp points. 
The type is in the Museum of the State University of Iowa. 
Sabellid genus and species? 
From tide pool at Needham’s Point was collected a fragment 
of a Sabellid too badly injured for identification, but it seems 
best to record what is possible on the chance that complete 
specimens may later appear. The gills are removed from the 
body. They are delicate, feathery, with no trace of eye spots. 
The collar is low, its ends separated widely dorsally but in con- 
tact ventrally, where each half ends in a short conical lobe. In 
the dorsal surface, anterior to the collar, are pigment patches. 
About 28 of the body somites are present and they all show 
the characteristic thoracic arrangement of sete with simple sete 
dorsally and uncini ventrally. The uncini are in a single row, 
each with a very long manubrium. There are no pennoned 
sete. The dorsalmost sete of the upper tuft are lanceolate at 
the apex, the ventral ones spatulate.
