‘VII.—Internal Parasites of the Fur Seal’ 
(pp. 99-177, and 100 text illustrations) is an 
elaborate report by Ch. Wardell Stiles and 
Albert Hassall, which incidentally includes a 
notice of the intestinal parasites of other marine 
mammals.

Fur Seals of Guadalupe, the Galapagos, and 
Lobos Islands’ (pp. 228-274, pll. xxii.—xxxv.,

torical and statistical, and a most valuable and 
comprehensive contribution.

‘X1V.—Practical Experiments in the Brand- 
ing and Herding of the Seals’ (pp. 525-588, pll. 
Xxxvi. and xxxvii.), is by David Starr 
Jordan and George A. Clark, who claim that, in 
a method of rendering the skins unsalable, they 
give the keynote to the whole situation, and, 
earried to logical conclusions, would ‘forever 
settle the vexed question of pelagic sealing.’ 
‘XV.—The Blue Fox of the Pribilof Islands’ 
SCIENCE. 
889 
(pp. 889-843), by D. S. Jordan and G. A. Clark, 
treats of the blue fox as one of the important 
resources of the islands, from the great com- 
mercial value of its fur, and recommends the 
protection of the herd from undue inroads.

consists of a carefully annotated list of the 69 
species of birds thus far known from the islands, 
with an analysis of their distribution and a dis- 
cussion of their migrations. The annotations 
are often extended and relate not only to the 
nesting and other habits, but to changes and 
conditions of plumage, etc. Pll. xxxix. shows 
variation in the markings of the eggs of the 
Pacific murre, and pll. xl. and xli. the devel- 
opment of feathers.
