“ZOOLOGY. 
Evermann and Marsh on the Fishes of Porto Rico. — One of 
the most thoroughly admirable of faunal works is the report on the 
Aquatic Resources and Fisheries of Porto Rico, just published by the 
United States Fish Commission. The authors are Dr. Barton 
Warren Evermann and Millard C. Marsh. 
In this work are given full descriptions of 291 species, arranged 
systematically, with analytical keys and numerous figures in the text. 
A general discussion of the waters and of the geographical features of 
the island is given by Dr. Evermann, and a chapter on the fish trade 
and fishing methods by William A. Willcox. 
The work is illustrated by 49 colored plates, by C. B. Hudson and 
A. H. Baldwin. The accuracy and excellence of these plates cannot 
be too highly praised. Without invidious comparisons we may doubt 
if any plates of fishes ever published excel in fineness of coloration 
Some of these (as the Nassau Grouper, Plate XII, and the Red 
Hind, Plate XIII) by Mr. Hudson. 
The nomenclature and definitions of groups are taken chiefly from 
Jordan and Evermann’s Fishes of North America, and the new species 
are mostly described in the final appendix to that work. 
Those not thus included are the following : 
Aphthalmichthys caribbeus, Gill and Sphagebranchus ophioneus, Mayaguez. 
mith, San Geronimo, 
Lycodontis albimentis, Culebra Island. Apogon sellicauda, Culebra Island. 
ps cleroperca bowersi, Culebra. Neomenis megalophthalmus, Puerto Real. 
Poi albifimbria, Culebutas. Scorpena bergi, Mayaguez. 
minus beanorum, San Juan. Emblemaria pandionis, Isabel Segunda. 
Citharichthys arenaceus, Mayaguez. Halieutichthys smithi, Mayaguez. 
The name Peprilus is substituted for Rhombus, preoccupied in 
mollusks. A few other changes in the nomenclature, adopted from 
Jordan and Evermann, will be found necessary. These may be
