Successional hairs are only occasionally seen. 



Each bundle is separated, from those around it by a deeply 

 staining, more or less compacted fibrous tissue. In the 

 ischiotergal patch, and on the chin and side of the head, the 

 bundles are more closely packed together than on the 

 shoulder, thigh, and. body generally. 



The large hair grows in various positions in the bundles, 

 generally posteriorly, but by no means always so. 



The muscles connected with the hairs are as usual unstriated, 

 both in the ischiotergal patch and elsewhere. 



Glands. 



In the modified patch, around the cloacal opening and on 

 the head, the sebaceous gland mass often almost entirely 

 surrounds the bundle, lying both between the latter and its 

 muscles, and between this bundle audits fellow. The glands 

 in this modified area, and tliose around the cloacal opening 

 are also very long, extending well down towards the hair- 

 roots, and even below them (PI 19, fig. 4), but on the side 

 of the head and under the chin, though the glands often 

 extend round the bundles, they are very much shorter than 

 in the ischiotergal patch specially. 



On the shoulder and thigh, as well as the general body 

 surface the gland mass is very much smaller and shorter (sec 

 PI. 19, fig. 4). The main duct of the gland is found most 

 often just behind the large hair of a bundle, and should the
