BARBADOS-ANTIGUA EXPEDITION 201 
greater or less quantity. A full list of the mollusks inhabiting 
the rocky harbor entrance would make quite a report in itself. 
Probably the most striking form obtained is a very pretty 
Turbinella of an apparently undescribed species. The shell is 
almost round, deeply corrugated by raised circular ribs and 
with a bright yellow aperture. Miss Sykes seemed to be the only 
collector with eyes properly focussed to detect these turbinellas 
clinging to the rocks, so well concealed are they by their color- 
ation and by the calcareous deposit that further hides them 
from their enemy (but not Miss Sykes). One of the chief 
enemies of these rock-living mollusks is a fish of the grouper 
family that at high tide swims about the reefs examining every 
inch of their surface for lttle mollusks that have not hidden 
themselves very carefully. The limpets and chitons cling too 
tightly to be dislodged. Collecting in such a locality means the 
overturning of many rocks, large and small, and is back-break- 
ing work. 
Many hundreds of dead and broken shells of the reef are oc- 
eupied by hermits that are also obliged to keep pretty well 
under cover. Just without the entrance to English Harbor the 
bottom is rough with areas of broken shell and coral detritus,— 
always a dead and unprofitable ground for the dredge. Unfor- 
tunately the constantly blowing trades made the sea too rough 
for our little launch to dredge upon the rocky, current swept 
island slope, although the 100 fathom line is hardly half a mile 
from shore. Two hauls only were accomplished on the slope, 
one at 120 fathoms and the second at some depth supposed to 
be between 200 and 300 fathoms, 2,500 feet of wire being used. 
The results seemed to be very meager at the time, but the sort- 
ing of the material shows these two to be the richest individual 
hauls in a total of some one hundred twenty or one hundred 
thirty made. The mollusks are all small and contain many tur- 
rids, Microgaza, Solariella, Ivotia, and some peculiar Triforis. 
Probably the one group most abundantly represented in our 
entire collecting is that of the Turritide (Pleurotomidx). Not 
less than fifty species of these interesting little mollusks were 
taken, many of them being heretofore known by one or two 
specimens only. A. striking species is Ancistrosyrinx radiata
