266 MARSUP1ALIA. 



down to the rectum, both of which have a ligament, and probably one 

 at the attachment of the mesocolon and rectum. 



The stomach was pretty full, in the contents of which I found 

 feathers, hair, wings, and legs of insects, and either the skins of insects 

 or scales of lizards or snakes ; but most probably of insects only. The 

 pancreas has the common structure, viz. a long one across the root of 

 the mesentery, and a short one in the mesoduodenum. The epiploon 

 is attached to the stomach forwards, to the duodenum on the right, to 

 the pancreas or root of the mesentery behind, and to the diaphragm on 

 the left. 



The liver is divided into three lobes, the right of which is subdivided 

 into two, besides smaller fissures, and has the vena cava entering it : 

 the middle lobe has the Hgamentum rotundum entering the substance 1 . 

 The gall-bladder is imbedded in a fissure on the under surface : the 

 lobulus Spigelii has one end behind the little epiploon, the other on the 

 right of the entrance into this cavity. The spleen is a long body on 

 the epiploon. The kidney is conglobate, with one long mammilla that 

 passes into the ureter 2 . 



The heart is oblique, as in the human subject; with a long vena 

 cava inferior, and two venae cavae superiores. 



The lungs have two lobes on the right side, one lobe on the left side, 

 and a pretty large lobe between the heart and diaphragm, belonging to 

 the right. The vagina may be said to begin within the verge of the 

 anus in the contracted or natural state of the parts, and passes on in a 

 straight line, but terminates in a large bag ; which bag terminates at 

 its most distant end in two obtuse ends, each of which has a little 

 lateral chamber : the inside of this bag is granulated. There are two 

 ora tincae ; or the horns of the uterus open separately into this bag by 

 projecting orifices, one on each side of the angle of the division of the 

 two obtuse ends of the bag. The horns are pretty large and convo- 

 luted, becoming larger towards their most distant ends, terminating in 

 the Fallopian tubes, which pass on the meso-Fallopian or capsula ovarii, 

 and open by two fringed edges near the ovarium on the edge of the 

 capsule ; this is large or wide at the mouth. The ovaria are flat bodies. 



The Tapoa Tafa [Dasyurus Tafa, Geoff. : Phascogale penicillata, 



Temm.] . 



This is a small animal of the size of a rat, with very much the 



1 [This would indicate a more prolonged uterine gestation in the pouchless 

 opossums than in other marsupials.]
