THE NAUTILUS. jOLE 
worth remembering, viz, never wear anything decent when collect- 
ing in the tropics. 
During our stay we drove around the entire island, visiting every 
parish. Owing tothe worthlessness of our team, the illness of the 
driver, and the almost incessant rains we encountered on the north 
side, our opportunities for collecting were greatly diminished. 
It was only when we stopped over a day or so at the towns that 
we were able to get any great amount of material. Strangely 
enough we found almost no marine species whatever. Occasionally 
on the rocky beaches we obtained Neritina virginea, a few Littorinas, 
Tectarius and Neritinas, but for miles, in fact along whole parishes, 
though the road ran near to the sea, and we watched closely, not 
even a valve was seen. 
The lack of marine forms was made up in the abundance of the 
land snails, and in some cases the fresh water species. In a branch 
of the delta of Roaring River, under a great breadfruit tree, H. 
picked up a dead Hemisinus lineolatus. Then I looked on the rocky 
and sandy bottom and found it alive by handfulls, and we met with 
it in quantities elsewhere. 
We kept an eager watch for the great white Helix aspera. My 
friend picked up asingle dead specimen on the road near Falmouth, 
and this fairly turned our heads. We inquired of every darkey 
from that on, hearing of it often like the Ignis fatutis, just a little 
way out of reach. Near Montego Bay we got afew more dead 
ones, and again as it was growing dark we discovered a dozen or so 
on the bushes and vines when we were nearing Savanna la Mar. 
The next day I started out early for a walk, resolved to find this 
snail if thorough search would do it. I tramped the whole forenoon 
and got only a few Ampullarias, and two o’olock found me tired, 
hungry, and thoroughly disgusted, seven miles from our hotel, and 
uncertain whether to push on to some low hills a mile ahead, or to 
give it up and go back. My resolve determined me and I went on. 
The first rounded knoll looked well at a little distance—one learns 
in a short time to distinguish good from poor localities a long way 
off. The elevation did not occupy more than half an acre ; red clay 
with decomposed limestone. It was originally a dwarf scrub which 
had been partly cleaved a couple of weeks before. The first thing 
I saw was a finedead Helix aspera on the ground, then others, there 
they lay thickly all around me, bright and fresh, with the animals 
nicely cleared out by tropic showers, the sun, and swarming insects.
