usually great size. The remarks on the morphology and innerva- 
tion of the anterior appendages are excellent, and have an inti- 
mate bearing on the systematic portion of these creatures, for Mr. 
Wilson sagaciously remarks that “it is easily possible that the 
external resemblances of a Pycnogonid to an Arachnid are those of 
analogy only, and have no morphological significance. This is the 
more probable from the extreme variability of the three anterior 
pairs of appendages in position and structure.” n the same 
Bulletin Mr. S. Garman reports on the Selachians, all captured at 
great depths, belonging to species hitherto unknown; the results 
of this and other deep sea work indicate (1) that the migrations of 
these animals, including the fishes, are much more limited in ex- 
tent than has generally been supposed; and (2) these creatures 
especially the skates, are more or less affected by a period of 
comparative inaction, in a measure corresponding to what obtains 
among Batrachia and Reptilia. Concerning the migrations of fish 
and Selachians, there are many species in our waters, the author 
remarks, “whose movements do not amount to more than short 
runs from shoal to deeper water and back again. Others would 
seem to extend their travels from the coasts and banks to the 
Gulf Stream. And still others make much more extensive migra- 
tions,” e anatomy of the African elephant is much less 
-known than that of the Asiatic species, which is naturally far 
more abundant in menageries and zoological gardens. Messrs. 
Plateau and Liénard have recently published the results of the 
dissection of an African species, with especial reference to the 
eart, larynx and male reproductive organs. Apropos of this in- 
teresting animal, it would seem probable that Yankee perse- 
Verance and painstaking may enable us to raise our own elephants. 
arnum’s baby elephant, born at Philadelphia, is growing rapidly, 
and is avigorouscreature in itsthird year. Itsmotheris again about 
seven months along in pregnancy, and it is therefore not unlikely 
that a second one will be born in this country. The sexes in 
Barnum’s herd of elephants pair readily in confinement. We learn 
on good authority that an American resident in India of thirty 
years, never heard of an elephant being born there, and was as- 
tonished at learning of the birth of one in the United States. 
. . Forbes has succeeded Professor Garrod as prosector 
to the zodlogical society of London. He is successfully rivaling 
his able predecessor in the quality of his papers, which are chiefly 
devoted to the anatomy of mammalia and birds.——Dr. Troues- 
sart has completed his catalogue of the mammalia as far as the 
end of the Rodentia, including that order with the Prosimie and 
the Quadrumana, ‘The number of species is so far 2001. The 
Catalogue will be very useful to students, as it includes synonymy 
ri geographical distribution, as well as the extinct species.——
