typically East Indian forms obtained. The list contains sixteen spe- 
cies not found along the mainland of Mexico, but which are nearly 
or quite identical with East Indian forms. This shows the compara- 
tive continuity of the Polynesian fish fauna. Six new species are 
obtained, Myrichthys pantostigmuis, Zalocys stilbe, Apogon atricandus, 
Forcipiger flavissimus, Cantherines carole, and Azurina hirando. All 
except the Apogon are figured; Zalocys, Forcipiger, and Azurina are 
new genera. Most of the species recorded were obtained by the use 
of dynamite among the rocks. 
We regret to learn from the daily press that, in a second expedition 
in the same region, Mr. McGregor, in his schooner, the „Stela 
Erland, has been wrecked on the coast of Lower California, all his 
valuable material being lost. DSI 
The Miller’s Thumb of Europe. — In the Proceedings of the 
Swedish Academy, Mr. Lars Gabriel Andersson takes up the vexed 
question of the relation of species in the genus Cottus, or Miller’s 
Thumb, as shown in the waters of Europe. 
This genus, in common with most others of relatively recent origin, 
exhibits surprising variations as represented in different waters; 
while, on the other hand, the characters which separate species are 
slight and sometimes unstable. 
After a very detailed comparison Mr. Andersson concludes that 
Cottus pæcilopus, of the Carpathian Mountains, is a species distinct 
from the common Co/tus gobio. Our own experience with the Ameri- 
can species of the same genus tends to confirm his conclusions.

Fishes of Santa Catalina Island. — Dr. Charles H. Gilbert 
reports, in the Report of the U. S. Fish Commission for 1898, on the 
Fishes obtained by the steamer 4/batross in the vicinity of Santa 
Catalina Island and Monterey Bay. A large number of deep-sea 
forms were taken, two of them, Radulinus boleoides and Averruncus 
sterletus, being new to science. Thesé species are figured in the 
report. Dy 3. ):
