1905. ] THE SECRETARY ON ADDITIONS TO THE MENAGERIE. 489 
In any case the tracheal lung does not exist in Amphishena 
brasiliana. The trachea opens into the lung some way behind 
the heart, and is only continued into the lung for a very short 
way. The short portion of the trachea which lies within the 
lung shows an irregularity in the cartilaginous rings, which are 
no longer uniform hoops. The rudimentary right lung is exactly 
half an inch long, and, like the long left lung, extends for a short 
way in front of the entrance of the trachea. The left lung 
reaches down the body as far as the end of the liver. Of the 
lung of Amphisbena (presumably the species fuliginosa) Dr. Wie- 
dersheim writes in the same work (referred to in footnote) : 
‘Die Lunge, deren interessantes Verhalten zur Trachea ich 
frither schon erwihnt habe, ist insofern héher entwickelt als 
diejenige der Lacertilier, als es kein einheitliches centrales Lumen 
mehr besitzt, sondern von einem feinen Balkchennetz durch- 
flochten ist.” The lung, in fact, of that species would appear to 
resemble that of higher Reptiles, such as the Crocodilia. In 
Amphisbena brasiliana there is nothing of the kind to be seen. 
The lung is a simple sac as in Lizards generally. It has not, 
indeed, even traces of a more complex structure, such as are to 
be found in many Lacertilia. The walls show the usual honey- 
comb appearance, and they are fairly thick, which would seem to 
allow of a considerable inflation of the lung. ‘These important 
differences between two species placed in the same genus would 
seem to suggest that the genera of Amphisbenide need revision. 
They are remarkably analogous, as I have observed, to the differ- 
ences which distinguish the Hamadryad Snake from the Cobra ; 
and these two are by many authorities confounded in one 
genus *.

The Secretary read the following report on the additions that 
had been made to the Society’s Menagerie in November 1905 :— 
The number of registered additions to the Society's Menagerie 
during the month of November was 147, of which 64 were by 
presentation, 24 by birth, 9 by purchase, 35 were received on 
deposit and 15 in exchange. The number of departures during 
the same period, by death and removals, was 166. 
Amongst the additions attention may be called to :— 
An Abyssinian Guereza (Colobus abyssinicus matschiet) and a 
White-tailed Mongoose (Herpestes albicauda) from the Upper 
Nile, presented by Mr. J. J. Harrison, on Nov. 3rd. 
A Water-Chevrotain (Dorcatherium aquaticum) trom Liberia,
