collection from La Union, on the Pacific coast, with Honduras. However, the Table

the large amount of information recorded in the numerous publications that have 
appeared subsequently to the dates of issue of this work, by Bocourt, Béttger, 
Boulenger, Cope, Dugés, Mocquard, Stejneger, and others; but as this supplementary

desire to bring the ‘ Biologia’ toa close, it has been decided not to delay the publication 
of the present volume. ‘Thus, all supplementary information, together with a report on 
collections received too late to be utilized for the present volume, must be reserved for 
a paper or papers to be published, I hope, at no very distant date.
