PP- 459, 460), canadensis Schreber (1778) is perfectly tenable for this 
species, for those who accept names based on plates, as does Mr. 
Miller in the case of the mink, Putorius vison (Schreber), which rests 
on the same basis as Zutra canadensis (Schreber) for the otter. 
Moreover, the name * canadensis " had been in almost universal use 
for this species till two years ago, when an unfortunate attempt was 
made to replace it by “ hudsonica,” of twenty-five years later origin. 
Another case that may be mentioned is the use of the generic 
name ‘“‘ Rosmarus " for the walruses instead of the prior name “ Odo- 
benus.” Rosmarus Scopoli dates from 1777; Odobenus Brisson 
from 1756, becoming perfectly tenable from Brisson's second edition 
of his Règne Animal, published in i762, or fifteen years before the 
tenable date of Rosmarus. We can hardly believe Mr. Miller has 
given these points due consideration. 
There are no really new innovations in the technical nomenclature, 
but a new subspecies of the common deer is described on p. 83, 
under the name Odocoileus americanus borealis. The number of 
species treated is ros, with thirty-three additional subspecies.

Pectoral Girdle of Reptiles. — Professor Max Fürbringer's' long 
interrupted studies on the comparative anatomy of the pectoral 
girdles and their muscles and nerves in vertebrates have been con- 
tinued in a fourth part devoted to these organs in the Amphisbaenia 
and the reptiles. The first 150 pages are devoted to an extended 
account of the skeletal elements of the pectoral girdles, breastbone, 
and humerus, including these parts in the fossil as well as in the 
recent representatives of the groups under consideration. This is 
followed by an account of the nerves to the shoulder muscles, after . 
which a very exhaustive description of the shoulder muscles them- 
selves is given. A final discussion of over 150 pages deals in a 
comparative way with the facts brought forward in the descriptive 
part and concludes with remarks on the phylogenetic relationships 
of the groups of reptiles to one another, to the birds, and to the lower 
vertebrates as shown by the structure of the parts described. The 
illustrations, some seventy figures in all, are beautifully clear and 
exact, and with the text constitute a work of monumental ge
