and fidelity with which they have done their work. All who are familiar with the 
life-colors of the species and who have seen these paintings have been struck with 
their accuracy, both as to color and structural detail. 
The lithographers, Messrs. Julius Bien & Co., have given faithful and satisfactory 
reproductions of the originals. 
Besides the colored plates of 49 species, 115 drawings were to be reproduced, each 
5.25 inches long, as cuts illustrating the text. But as these pages were being written 
all of these drawings were destroyed by fire in New York. Steps were at once taken 
to have the 28 new species redrawn. Some of the others can not be replaced, but 82 
of them had recently been reproduced in the “Fishes of North and Middle America,” 
by Jordan & Evermann, and through the courtesy of the U. S. National Museum the 
same blocks are used for illustrating this report, but we were thus compelled to 
have them appear 4.25 inches long instead of 5.25 inches, as originally intended. 
Another serious loss was incurred by the burning of the model and training- 
school at San Juan, July 1, resulting in the total destruction of a valuable collection 
of fishes made in the vicinity of San Juan by Mr. Oscar Riddle, and his notes upon 
them, both of which he was about sending for use in preparing the present paper. 
As already stated, the investigations of the Fish Commission in Porto Rican 
waters, though extending over about forty -five days and really embracing not over 
thirty-eight days of actual work, resulted in adding to the known fish fauna of the 
island nearly 200 species, among which were 3 genera and 33 species which are new 
to science. The 3 new genera and 20 of the new species were described by the present 
writers in the Annual Report of the IT. S. Fish Commission for 1899. 1 
One of the new eels (Aphthalmichmys caribbeus ), the type of which was collected 
by Mr. G. M. Gray, was described by Drs. Gill and Smith in Science for June 22, 1900. 2 
The following is a full list of the new genera and species resulting from these 
investigations. Those which appear for the first time in this report are indicated by 
the star. The number following each name is that which the type specimen bears on the 
register of the U. S. National Museum, in which all the types are deposited. Cotypes 
of species of which duplicate specimens were obtained are in the reserve series of the 
U. S. Fish Commission and in the Museum of Leland Stanford Junior IMi versify.
