Order Insectivora. 

 Section Cheiroptera. 



Large Bat, South Seas [Pteropns 1 ] . 



The anus appears to be upon the lower part of the belly ; and just 

 close upon the anus is the mouth of the vagina in the female, and of 

 the prepuce in the male. There is no caecum. The epiploon is very 

 small, attached to the stomach, pancreas, and spleen, between which 

 parts it is almost stretched. The liver is divided into five lobes with 

 the lobulus Spigelii ; the gall-bladder is attached to the second from the 

 left side by a thin membrane. The kidneys are conglobate. 



The lung on the right side is divided into three lobes ; the middle 

 lobe is fissured, and the lower or third lobe sends in the lobe behind 

 the vena cava ; the lung on the left side is divided into two lobes, the 

 lower of which has a fissure in it. The trachea is as in the quadruped. 



Upon the fore part of the pericardium are placed two flat glandular 

 bodies which almost cover the anterior part of the heart. 



The common vagina goes considerably higher on the under side than 

 the os tincae. There are two horns which open into one common uterus. 

 This bat has one young at a time, and there is one placenta, which is of 

 the [discoid type]. The foetus and appendages occupy one horn and 

 the whole of the common uterus 2 . 



Of the Male. — The penis is large, with a bone at the glans, the testi- 

 cles are large, and lie in a sulcus, just oiit of the abdomen ; but seem, 

 when looked to from the abdomen, as if this could be easily pulled in. 

 The vesiculag seminales are large. 



The Bat [Vespertilio]. 



The stomach comes to a point at the large end, which is a little 

 turned up. The duodenum is Hke [that in] other animals. It has no 

 caecum. The intestines are very short, like those of the martin, about 

 three times the length of the animal 3 . 



The liver is divided into three lobes, but I could not find any gall- 

 bladder. The kidneys are pretty large, that is, longer than common for 

 such a sized animal.
