genus near Liparis. The Embiotocidze, or surf fishes, consist of 
two species in Japan, Ditrema temminckii and Neoditrema ransonneti. 
The Pediculati, or angler fishes, of Japan consist of eleven species, 
the following being new: Antennarius nox, A. scriptissimus, A. sangui- 
Juus, Malthopsis tiarella. The last two papers are by Dr. Jordan, 
assisted by a Japanese student of fishes, Michitaro Sindo. 
Mr. William H. Gregg has published a convenient volume on 
When, Where, and How to catch Fish on the East Coast of Florida. 
The greater part of the book is devoted to a systematic account 
of the game fishes of the east coast of Florida, with numerous 
figures taken from government publications. The systematic part 
is arranged from the writings of Jordan and Evermann, which is 
very proper when credit is given, as Mr. Gregg has been careful to 
do. To make popular works of this sort possible is one of the duties 
of the systematist. After describing the fishes Mr. Gregg tells in an 
accurate and readable fashion how and when to catch them. 
In the Annals and Magazine of Natural History (Vol. IX, No. 51), 
Dr. G. A. Boulenger discusses the classification of the berycoid fishes. 
He finds that this group differs from the percoids in no important 
respect, and regards the berycoids as merely archaic percoids. The 
chief diagnostic character, the increased number of ventral rays, is 
found in most berycoids. Pempheris, however, differs from Beryx 
almost solely in having the usual number of ventral rays, I, 5, found 
in most spiny-rayed fishes. Zeus and Grammicolepis, perhaps not 
related to Beryx, have also an increased number. Aphredoderus is 
placed among the berycoids by Boulenger. The resemblance of the 
fossil genus Asineops to the Berycidz is also noted, while Erisma- 
topterus is thought to have no near affinity. To the present writer 
Erismatopterus resembles the Percopsidze, having much in common 
with Columbia. Boulenger rightly separates Pempheris from the 
Kurtidz, and he suggests the close relationship of both Pempheris and 
Bathyclupea to Beryx. Stephanoberyx and Malacosarcus he would 
place among the Haplomi. Polymixia he regards as an ally of Beryx, 
and Morocentris as a more distant relative. Hoplostethus he unites 
with Trachichthys, while a new genus, Gephyroberyx, is proposed 
for Trachichthys darwini. The genus Paratrachichthys with the vent 
advanced is rightly regarded as valid. D. S.J.
