BARBADOS-ANTIGUA REPORTS 19 
Under the name Dasychone wyvillet McIntosh described a 
specimen from St. Thomas, West Indies. His specimen was 
without gills but in the general form and color of the body, the 
position of the anal opening, the character of the fecal groove, 
the form and color of the collar, and the character of the sete, 
his description applies accurately to the specimens under con- 
sideration. The only detail in which the resemblance is not 
close is that his figure 3, labeled as an anterior (thoracic?) 
uncinus, has a shorter manubrium than any I have seen, re- 
sembling in this respect more closely those of the abdomen. 
The gills are prominent. Each half is inrolled at the base 
so as to form about three-fourths of a cirele. There is a dark 
brown basal portion with a height of 5 mm. where the height 
of the whole gill is 50 mm. Beyond the basal portion each 
rachis is entirely free. Each rachis has bands of dark brown 
alternating with colorless regions. Where the color appears it 
is continued over the corresponding filaments. Through the 
middle of the rachides the filaments are six times as long as 
the diameter of the rachis, but toward the apex of the latter 
they are shorter and entirely disappear near the end, leaving 
the latter bare. There is no trace of either eye spots or ap- 
pendages on the dorsal surface of the rachides but each has 
a shallow, pigmented groove along its mid-dorsal line. 
Having no external appendages on the gills, having avicular 
uncini in a single row on all somites but the first thoracic, and 
the abdominal uncini having longer manubria than those of the 
thorax, these belong in the genus Jasminiera Langerhans, as 
that genus is ordinarily defined. Chamberlin however (1919, 
page 471) shows that Jasminiera should be replaced by Bispira 
Claparéde, and that species having spiral gills which are or- 
dinarily listed as Bispira should be transferred to the genus 
Distylia Quatrefages. 
The animals may reach a size where the body length is 110 
mm. the gills of such individuals reaching a length of 70 mm. 
The tube is composed of fine mud without much organic matter 
so that it breaks very easily. Its wall is about 1 mm. thick. 
Over 70 individuals were in the collection mostly from Eng- 
lish Harbor. Others were from sea wall, Dock Yard.
