Laguna della Pita. Aippoglossina sabanensis from Rio Sabana, In 
this paper Dr. Boulenger seems to have abandoned his respect for 
the law of priority in nomenclature, to which he has usually shown 
a proper regard. There is no obvious reason for reverting to Meso- 
prion, when Lutjanus has priority and the sanction of large current 
usage. Nor is there any justification for using Pristifoma for Poma- 
dasis. Naturalists must either use the oldest unoccupied generic 
name, or else abandon all rule and each one do as he pleases. The 
result of this line of action is the present confusion, from which the 
rigid application of the law of priority offers the only means of escape. 
In the same Bulletin Dr. Boulenger continues the discussion of the 
fishes of Ecuador collected by Dr. Enrico Festa. The species for 
the most part are identical with those found at Panama. The follow- 
ing new species are described: Pristifoma labraciforme from the Bay 
of Ste. Héléne, Santa Elena, a species close to Poey’s Pomadasis 
ramosus, Hamulon helene from the Bay of Santa Elena, Corvina 
miacanthus from Guayaquil. This species belongs to the modern 
genus Bairdiella, Heros feste, from Rio Guayas, Guayaquil. 
In the Annals and Magazine of Natural History Dr. Boulenger 
notes the occurrence of Lepidopus (or Benthodesmus) atlanticus at 
Madeira. The same species has been also recorded from Portugal 
under the name of Zefidopus argenteus. He also discusses the spe- 
cies of the genus Callanthias and describes a new Anabas from the 
Congo. 
Under the auspices of the Department of Agriculture of the Cape 
of Good Hope, Dr. Boulenger describes two new gobies from the 
Cape, Gobius gilchristi and Callionymus costatus. 
In the Proceedings of the Zoölogical Society of London Dr. Boulenger 
has a valuable review of the genera and species of Mormyridæ. In 
this paper stress is laid on the numbers of vertebræ, and these have 
been counted by means of the Röntgen rays, an interesting applica- 
tion of a discovery in physics to systematic zoölogy. DSI 
Teeth of Lizards and Snakes. — The structure and development 
of the teeth in lizards and snakes have been studied by Dr. H. Levy." 
The outer enamel layer and the inner dentine layer are clearly dis- 
tinguishable, and there is no transition in these two layers, as has 
been claimed for the lower vertebrates. In the development of the
