in the deep seas of the Antarctic, as well as the shore waters, 
trachinoid fishes related to Percophis and Notothenia are numerous 
and characteristic. 
In the Proceedings of the New England Zoological Club, Mr. Samuel 
Garman shows that the Japanese deep-water Chimzra described by 
Professor Mitsikuri as Harriotta pacifica is the type of a new and 
still more primitive genus, which he calls Rhinochimera. It differs 
from Harriotta by the possession of teeth like the horny covers of 
. the jaws on tortoises and birds, without the separate tritors found 
in Chimera, Harriotta, and Callorhynchus. Garman divides the 
group into three families, Chimzride, Callorhynchide, and Rhi- 
nochimzridz, the latter including Harriotta. Garman makes the 
important discovery that the frontal holder or cartilaginous hook 
on the forehead of the male is present on the adult of Harriotta 
and Rhinochimera as well as on Chimzra and Callorhynchus. As 
with the ventral claspers, this is developed only when the animal is 
sexually mature. Its presence is therefore a distinctive character 
of all the living Chimera-like fishes, and it is found in no other 
fishes. Mr. Garman’s paper, though brief and not illustrated, is a 
most valuable addition to our knowledge of these fishes. 
Under the head of * The Smallest Known Vertebrate," Dr. H. M. 
Smith gives in Science for Jan. 3, 1902, an account of a diminutive 
. goby only fifteen millimeters long when adult, found in Lake Buki 
in southern Luzon, where, from its great numbers, it is an article of 
food of considerable importance. It is named Mistichthys luzontus. 
The genus is very close to the Japanese Euteniichthys, also very 
diminutive, but it has larger and rougher scales than the latter. 
In the Bulletin of the Museum of Paris for 1901, Dr. Pellegrin 
notes a collection of fishes obtained by M. Diguet in the Lake of 
Chapala and in Rio Lerma in Mexico. Most of the species have 
been already noted by Jordan and Snyder. One new species, Xenen- 
dum multipunctatum, is described from the pond called Agua Azul, 
near Guadalajara. I cannot agree with Dr. Pellegrin that Ameiurus 
dugesi of Lake Chapala is the same as Ameiurus catus, nor that the 
little Gambusia infans is the same as G. affinis. 
Under the head of “Les Poissons Vénéneux,” Dr. Jacques Pel- 
legrin of the Museum at Paris publishes a valuable account of the 
fishes of which the flesh is known or suspected to be poisonous. 
It appears that in Tetraodon, Spheroides, Tropidichthys, Balistes, 
Monacanthus, and other genera — mostly globefishes, filefishes, and
