species now recorded from Brazil; Atherinichthys salle for a new 
species of Menidia from Mexico; Serranus flaviventris should 
include S. dispilurus, S. subligarius, and S. brasilienis. It is distinct 
from S. auriga. Diagramma geldii is identical with Genypterus 
cavifrons, for which species Mr. Regan does not accept the older but 
somewhat doubtful name, /uteus. Mylacrodon geldii is a new genus 
allied to Pomadasis but with some molar-like teeth. 
The Old World genera, Gazza and Leiognathus, are referred to 
the Gerrid&, from which they differ in the small scales and in hav- 
ing the gill membranes narrowly united to the isthmus. Regan gives 
an analysis of the striped species of true Gerres he regards as ten- 
able, viz., brevimanus, plumieri, mexicanus, lineatus (including brasil- 
ianus and embryx of the Atlantic coast), axillaris, and patao. G. 
brasilianus is, however, not the same as G. /ineatus. 
Pristedion altipinnis new species; Oligoplites saliens (with four 
dorsal spines) is a valid species, as are also O. palometa, altus, saurus, 
and mundus. ; 
Not knowing the species of Spanish Mackerel, called Scombero- 
morus regalis, Regan identifies it with S. maculatus. The fishermen 
know better. Scomberomorus immaculatus from San Domingo is not 
identical with S. cavala. 
Genypterus brasiliensis, new species ; Achirus fonsecensis is recorded 
for the first time from the Atlantic and Lophius piscatorius for the 
first time from Brazil. 
In 1900, the “ Albatross” made a short dredging cruise on the 
coast of Japan, taking 111 species of fishes. Of these, 58 were new 
to science and have been described by President Jordan and his 
associates. In a paper in the Bulletin of the United States Fish 
Commission for 1903, figures of all these new species are given, with 
references, notes, and descriptions of a number of new species. This 
memoir is by Jordan and Starks. With it is included a monographic 
review of the Macrouride, or Grenadier-fishes of Japan, by Jordan 
and Gilbert, with figures of most of the numerous species. 
The most important faunal work in ichthyology for the year is the 
account of the Fishes of Panama Bay by Professor Charles H. 
Gilbert and Mr. Edwin C. Starks, published by the California 
Academy of Sciences (Mem., Vol. 4), and reprinted by the Hopkins 
Seaside Laboratory of Stanford University. 
This paper contains a very full account of the fishes of Panama,
