^ LOPHOBRANCHII. 
^ Prof. Canestrini believes that in Lophobranehs a coitus 
takes place, during which the ova are transferred from the 
female to the male, which fecundates them after they have j 
entered the ovigerous sac. [If this be so, a concourse of the i 
sexes might be assumed also in the Siluroid genus Aspredo.~\ 
In young Hippocampus he has discovered a caudal fin, as Fries ! 
5 
pocampus from Calcmosioma ; besides, Nerophis is a genus in ' 
process of formation. The paper is concluded with a descriptive 
and analytical catalogue of the Lophobranehs of the Adriatic — i 
Hippocampus with 2, Siphonostomus with 2, Syngnathus with 6, 
and Nerophis with 2 species. Att. 1st. Ven^t. xvi. 1871, or Bibb 
\ 
also had found rudiments of tins in young Nerophis. The 
author relies on these facts to establish the genealogy of some of 
the genera: Nerophis is descended from Syngnathus, and Hip-^ \
