The above lists show about all that was available to the 
writer concerning the shells of Magdalena bay at the beginning 
of 1917. March 1, 1917, the writer sailed out of San Diego bay, 
California, on a small boat, which arrived on the evening of the 
4th, six hundred miles south, in Magdalena bay. On the morn- 
ing of the fifth he landed on Magdalena Island at the little settle- 
ment. officially known as ““Magdalena Bay,” with its custom house, 
post office, and a miscellaneous collection of some two dozen 
buildings. 
~ The first few days were devoted to the botany of Magdalena 
Island. But being too late in the season, his whole time, for the 
next thirty days, was chiefly spent in collecting shells, taking 
ship again on Anri!l 6 for San Diego. A few days were spent in 
a vis*t to Santa Margarita Island, Puerto Viejo and Port Charlie, 
- onthe pen’nsular side of the bay, otherwise the a as were 
S all made on Magdalena Island. 
The. first night I found myself behind iron bars, in a big 
concrete house on top of a hill, overlooking Man-of- War Cove, a 
jail-like structure built perhaps fifty years ago by the owners of 
the Hate concession—a grant of land about twenty miles wide, 
extending along the coast of Baja California for a distance of 
two hundred twenty miles! J had expected to camp out and con- 
coct my own meals—but the local manager for the present own- 
ers of the concessicn insisted on my occupying the Casa Grande 
with him, and his native cooks took all the concccting off my 
~hands. I found myself mainly dependent on this same local des- 
pot for the use of boats and labor required from time to time, 
and being the only American within a hundred miles or more he 
furnished most of the companicnship enjoyed. 
Along the shore of Man-of-War Cove, every morning during 
my stay, was to be found a fresh lot of shelis washed up and 
left by the tide. Chief among these were dark purple specimens of

with now and then a salmon-colored specimen, generally a few 
with bright p'nk or reddish rays, and usually a large number of 
pure white specimens, ofien still living, and all as bright, perfect 
specimens as could be desired. These shells are often collected
