BARBADOS-ANTIGUA EXPEDITION 93 
elosely allied. Our little red Ovulum carnea is an important 
link. 
The Barbadian secaphopods include about 16 species, repre- 
senting several subgenera. Four of the five caduli are only 
Barbadian as so far known. The most striking of the dentalia 
is D. stenoschizum P. and S. which possesses an exceedingly 
long apical slit, quite a fourth the length of the shell. D. 
laqueatum described by Verrill from Cape Hatteras and a very 
abundant species off the Florida East Coast, appeared in our 
dredge. Without any intervening records this becomes a very 
long distributional leap. The only Antiguan scaphopods we 
met are two caduli, both new species. 
Almost every haul of the dredge made in rough ground brought 
to our collection some brachipods. Probably the commonest was 
the little Argyrotheca rubrotincta Dall which cling to the frag- 
ments of coral rocks and dead shells and seemed ever-present 
like little pink or red pendants on the dull background of their 
abodes. Another species of the same genus much less abundant, 
A. lutea Dall. is found off the Florida Keys and even to Hat- 
teras. We have it from 12 stations (all Barbados) 33 to 100 
fathoms. Very abundant was Terebratulina cailleti Crosse, a 
species ranging from Florida to Rio. We have 35 lots. The 
method of attachment to stones in these Brachiopods is so very 
different from that of any bivalve mollusks that they are quickly 
recognizable. One always feels a sense of awe in collecting 
these survivors of the past ages. Their antiquity is remotely 
ancient, even to the Cambrian, and their course of existence is 
probably run out. At one time they represented a most im- 
portant element in the total of life on earth,—now they are re- 
duced to a few species scattered about the world and occupy a 
most subordinate place in any faunal census. That they should 
have survived at all through such countless ages is probably due 
to their very wide distribution. 
A few dead specimens of Liothyriana (‘‘Terebratula’’) 
cubensis Pourtalés were encountered in 90-100 fathoms, Barba- 
dos. This beautiful brachiopod clings in clusters like greenish 
hued grapes to the stones of the Pourtalés Plateau off the Flor-
