The matter is still somewhat in dispute, but since the publication 
of Marshall’s researches on the subject, and the confirmation (in the 
main) of them by Van Wijhe it may be taken as established that in 
front of the vagus group of nerves four segmental nerves exist. These 
may be taken to be represented by: no. 1. The Motoroculi; no. 2. Tri- 
geminus; no. 3. Facialis; no. 4. Glossopharyngeus: The Olfactory 
nerve has been omitted from this list, because its segmental nature is 
still disputed. But even if the latter nerve be considered a segmental 
nerve, I think the very special function it fulfils sufficiently accounts, 
in accordance with Dohrn’s principle of change of function, for the 
absence of any innervation by it of segmental sense organs. 
It would have been impossible before the researches of Van Wijhe : 
to classify the Motoroculi among those segmental nerves which supply 
segmental sense organs. But, according to Van Wijhe, a »Zweig 
des Ganglion Ciliare« goes to an epidermis thickening which becomes 
a segmental sense organ. 
The nerves of the second and third segments, viz. the 5th and 7th 
cranial nerves, give in common, according to the same author, a 
branch to the supply of segmental sense organs. He says: »Beide 
Nerven (Ram. buccalis und Portio facialis) entstehen gegen das Ende 
des Stadiums J. oder den Anfang des K., gemeinsam als ein kurzes 
Rudiment (Ram. Oph. Sup.), welches, vom Facialis nahe an seinem 
Austritt aus dem Gehirn entspringend, in eine kleine hinter dem Auge 
befindliche verdeckte Stelle der Epidermis endet« etc. 
Like the three preceding the fourth segmental nerve or Glosso- 
pharyngeus gives off a dorsal branch to supply its segmental sense 
organs.

1. Zoologica! Society of London. 
5th February, 1884. — Mr. F. Day, F.Z.S., exhibited and made re- 
marks on a specimen of a Dog-fish, of which the entire interior had been 
eaten out by Isopod Crustaceans of the genus C'onilera. — Mr. G.F.Butt, 
F.Z.S., exhibited two specimens of a singular variety of the Red Grouse, 
shot in Westmoreland. — A communication was read from Mr. W. Leche, 
of the University of Stockholm, in which he gave an account of a collection 
of Bats from Australia. Two new species were described and named re- 
spectively Nyetinomus Petersi and N. albidus. — Mr. Sclater read some 
notes on the Lesser Koodoo (Strepsiceros imberbis of Blyth), with a view of 
confirming the distinctness of this Antelope from its larger relative Stepsi- 
ceros kudu. — A communication was read from Mr. R. Bowdler Sharpe,
