may be the true sexual orifices. The oviduct and the so-called 
“false ovaries ” do not differ from the description and illustration 
given by Dana and Pickering (C. americanus). A pair of smaller 
roundish “ glands” occurs a little behind the middle of the intes- 
tinal tract. Another pair of larger roundish masses, of a yellow 
color, occurs more laterally and more posteriorly than the pre-

ZOOLOGY AT THE NAPLES Sration.—The third volume of the 
briefer papers and memoirs emanating from the zoological station 
at Naples, dated 1882, form a thick octavo volume entitled Mitt- 
heilungen aus der Zoologischen Station zu Neapel. One of the 
more notable articles is that in continuance of Dr. Lang’s re- 
searches on the comparative anatomy and histology of the ner- 
vous system of the flat-worms; also his paper on the structure of 
Gunda. To Ceelenterate literature belong A. Weissmann’s paper 
on a peculiar organ of Eudendrium racemosum; Bedot's notice of 
the Siphonophores of the Gulf of Naples; Andres on a case of 
scissiparity in an Actinia; G. v. Koch’s notice of the Neapolitan 
Gorgonians and the development of Gorgonia verrucosa ; and his 
essay on the development of the coral-stock. A parasitic Eunice-

treated by Kossmann in his ron the Entomiscidz, and his 
studies on the Notodelphyidz. A contribution to ichthyology by

tory of the vertebrate body are the more purely zoological con- 
tributions,

their place. In the first stage of its development the structure of 
the electric organ is similar to that of embryonic muscle, as dis- 
tinct longitudinal striae and traces of transverse striation are 
evident. 
KING-BIRDS, TYRANNUS INTREPIDUS, FEEDING THEIR YOUNG UPON 
Fruit—In the summer of 1880 a pair of king-birds had their
