A heavy shower of rain, by bringing out the landshells, enabled me to pick up half-a-dozen species of Helix, Bulimus, and Pupa, at the foot of the hedgerows; I was anxious to procure some to ascertain whether any were non-European forms; one was even quite a new species.
One of our Land-snails, the Bulimus, whose shell is continued into a turret, moves almost in the same fashion, tumbling repeatedly as he goes. The Clythra's is a shapely jar and does credit to the insect's art of pottery.
He closes the occupied part with a stout partition-wall at the back; then, dashing against the sharp stones, he chips off the superfluous portion, the hovel not fit to live in. The broken shell loses its accurate form in the process, but gains in lightness. The Clythra does not employ the Bulimus' method.
There was very little water, and that little saline: the whole country, from the coast to the Cordillera, is an uninhabited desert. I saw traces only of one living animal in abundance, namely, the shells of a Bulimus, which were collected together in extraordinary numbers on the driest spots. In the spring one humble little plant sends out a few leaves, and on these the snails feed.
Among them was the Helix barbula, an Asturian species, Helix pauperata, and Bulimus variatus, Madeiran or Canarian forms. A considerable number of marine and terrestrial Testacea were procured at Rio de Janeiro, not a few of them new and of great interest. Terebratula rosea was dredged off Rio in thirteen fathoms water, on a coarse sandy bottom.
Melania turritissima, Forbes. a. Fragment of carapace of Trionyx. b. c. Bulimus ellipticus, Sowerby. Helix occlusa, Edwards. Paludina orbicularis. Planorbis discus, Edwards. Lymnea longiscata, Brand. Chara tuberculata, seed-vessel. d.
The big Broken Bulimus, that lover of crumbling walls and limestone rocks leaning in the sun, sacrifices the graces of symmetry to utility. When the lower spirals are no longer wide enough, he abandons them altogether and moves higher up, into the spacious staircase of recent formation.

The captain and his mate enjoyed their supper, while Carne in the distance bore the pangs of a malady called bulimus, that is to say, a giant's ravening for victuals, without a babe's power of receiving them. For he was turning the corner of his sickness now, but prostrate and cold as a fallen stalactite. "Aha! We have done well. We have warmed our wits up.
Among the shells we found a Helix of a brownish colour and of an oval form, approaching that of Bulimus. Whilst my companions returned to Brown's Lagoons, Mr. Calvert and Brown remained with me to examine the country.
