from what occurs in the immediate vicinity of Miami, but the 
expeditions to Virginia Key and later to Biscayne Key, Soldiers’ 
Key, Sand’s Key, and Elliott’s Key, brought us into closer rela- 
tions with the open ocean and the Gulf Stream and yielded results 
of much interest. Caesar’s Creek, south of Elliott’s Key, proved 
to be a particularly rich collecting ground. , 
Five days were spent on the island of New Providence, Baha- 
mas. The south shore of this island, with its wide stretches of 
shallow water, was the most interesting of any part visited and I 
regret that only one day was given to it. On April 11, Dr. 
Millspaugh and I having chartered at Nassau the sloop-rigged 
yacht ‘‘ Cynosure,” began a westward voyage of exploration with 
e 
pective terminus. Our first stop was at West End Bight, New 
Providence ; afterwards, we touched and made collections at 
Joulter’s Cays, Gun Cay, North Cat Cay, and the Bimini Cays, 
returning then to South Cat Cay, from which we took our course 
across the Gulf Stream to Miami. Inthe Bimini harbor, a fea- 
ture of special interest was the development of the genera Pevz- 
cillus and Rhipocephalus, which include the so-called ‘‘ merman’s 
shaving brushes.” Four species of Penzcil/us and two of Rhipo- 
cephalus were found growing in this harbor. Extending east- 
ward from the harbor proper are extensive sand flats which are 
widely exposed at low water; the portion which lies between 
the tide-lines is almost re of plant-life, but the region from 
low water mark down to a depth of six feet seems particularly 
well adapted to the members of the Penicillus group. 
Ten days were occupied in the cruise from Nassau to Miami. 
The only misadventure, if it may be called such, of the voyage 
was our meeting with two or three dead calms at sea, which 
delayed our schedule by about three days. One almost breath- 
less day on the deep waters of the Gulf Stream resulted in carry- 
ing us forty or fifty miles north of our course. These experiences 
served to emphasize the superior value, for future expeditions, 
of a sailing craft with an auxiliary engine. However, a dead 
calm on a Bahaman bank covered with only ten or fifteen feet 
of water is not without its compensations to any one who is inter-
