Tryon can be considered to be one of the most prolific malacologists, publishing more than 1,000 articles and books, and naming more than 5,600 new species. He started the ongoing multi-volume Manual of Conchology (1879), when he died nine volumes of the first series had been published, the work continued until 1935 and ran to 45 volumes.

Tryon is honoured in the names of a genus, Tryonia, and in the names of a number of species under tryoni(i) and tryoniana.
