1889.] THE BODY-CAVITY IN LIZARDS, ETC. 465 
(cf. Plates XLVI.—XLIX. figs. 1-4 and woodcut A, p. 465), and 
the membranes between the lung and liver are the pulmohepatie 
ligaments. 
The ligaments of the right side and consequently the corresponding 
recess is fully developed in the following genera :— 
Lacerta (viridis, muralis). Uromastyz. 
Iguana (tuberculata). Chameleon. 
Gerrhosaurus (flavigularis). Sphenodon. 
Goniocephalus (sophie). Trachidosaurus. 
In the last-named genus the posterior end of the lung is attached 
by a separate membrane to the ligament between the liver and dorsal 
wall. 
The Teiide are the only family in which I have met with the 
condition in which the lung of each side is suspended freely by its 
more dorsal ligament, with a consequent absence of pulmohepatic 
recess. 
This condition is visible in the following, which are the only 
representatives of the family that I have examined :— 
Tupinambis (teguivin) (Tejus teguexim, Gray). 
ag (nigropunctatus). 
Ameiva (surinamensis). 
Callopistes (maculatus). 
The two types of lung-suspension referred to may be thus diagram- 
matically represented *:— 
Fig. A. Diagrammatic section of one of the lizards included in the first list 
given above, taken through the lungs and liver. 
Fig. B. A similar section of one of the Teiidz, mentioned in the second list. 
a, pulmohepatic ligament; ws, cesophagus; h, h', right and left liver-lobes; 
m, median thoracic septum ; pul, lung. 
A second set of attachments of the liver frequently met with are 
ventral ligaments that run outwards from the pericardium, or the 
1Tt may be noted that two similar types occur among the Amphibia. 
Thus, in the Salamander all the membranous attachments of the lungs and 
liver seem to be precisely similar to those in the common Lacertilian type 
(e.g. Lacerta). But in the Frog the two lungs hang freely suspended on either 
side, as in the Teiidx,
