476 Anatomy of Ailurus, Porcula, aud Stylocerus. [Nov. 



preputial sac or gland, and lastly, furnished with a small simple bone. 

 Teats of female 8. Her vulva simple, that is, without trace of prepu- 

 tial gland. Anus of both with a large nude margin, but no appearance 

 whatever of special anal glands, and no other semblance of pores than 

 two very shallow simple reduplications of the skin, having a central 

 lateral position (one on each side), probable only subservient to the 

 lubrication of the parts. Peroneum of both sexes hairy and void of all 

 trace of glands. 



Ailurus ochraceus. Soft anatomy. — Male 1 2j inches long from snout 

 to anus. The male's thoracic and abdominal viscera are as follows : — 

 The lungs have 4 main and 6 total divisions, and are disposed bilaterally 

 on each side the sesophagus. The liver has 3 main divisions, that is, 

 the laterals and the central. Of these the laterals are bifid, and the 

 central, trifid, and there is no lobulus, so that the total divisions are 7. 

 The lateral lobes are the larger and are very unequally divided. The 

 gall-bladder is half imbedded in one of the clefts of the central lobe, 

 and is of an elliptic shape, pouring its thin yellowish bile into the intes- 

 tine about two inches below the stomach by one long clear duct. The 

 pancreas is a very fragile, colourless, glandular, linguiform organ lying 

 parallel to the biliary duct and close in contact with it. I could not 

 satisfactorily trace the pancreatic ducts ; but there seemed to me to be 

 one, very short, put oif from the lower or posteal end of the organ, and 

 entering the intestine close to the entrance of the biliary duct, perhaps 

 \ inch above it. Spleen 3 inches long by two, dark-coloured as a giz- 

 zard, tongue-shaped, and lying along the greater arch of the stomach 

 with merely membranous attachments thereto. Heart 1^ inch long by 

 \\ of greatest diameter, muscular and firm. Stomach pyriform, inclin- 

 ing to hemispherical and decidedly of the solvent type, though its outer 

 coat shows some faint signs of muscularity upon the surface of its equa- 

 ble, thickish and membranous walls. Inner coat of uniform surface, 

 void of folds or bands. Orifaces nearly but not quite terminal. Greater 

 arch of the stomach 1\ inches ; lesser, 2 inches. Towards the pyloric 

 orifice is a sort of subsidiary stomach, extremely glandular and resem- 

 bling in character but not in position the succenturiate ventriculus of 



men. The special secretory glands are preputial and form a parallelogramic nude 

 subvalvular field, in the centre of which lies the large membrum. In the female the 

 lips of the vulva are the seat of the glands.
