Now concerning the tuft. This tuft is found on maies in C. limbatus 

 pumilus, and hindei, and arises in each case from the back of the mem- 

 brane Connecting the ears (Allen's sub-genus Lophomops, in which 

 he includes his species chapini, cristatus, and abae). It will proba- 

 bly be found to occur in other species such as emini. When at rest 

 the tuft covers a bald patch on the crown of the head. The tuft is a 

 sexual character and is wanting in the females, but it is curious to 

 find that quite a number — about 50 °/ — of thèse show the bald 

 patch on the crown. 



In maies the bald patch is always présent, but in young spécimens 

 the tuft is lacking. It is difficult to know at what âge and in what 

 circumstances the crest is developed. Out of seven limbatus taken on 

 the same day, and probably from the same roost, at Mombasa by 

 Mr. Arthur Loveridge, five are without the tuft, although they 

 appear in other respects adult. 



Thèse considérations lead me to think that C. limbatus, frater, 

 and cristatus are one and the same bat.

25. — Chaerephon sp. 



162. Kisantu. 



Perhaps a young limbatus. The skull labelléd with this number 

 belongs to a Plecotus.

A richly coloured race of tordayi, with the undersuiface strongly 

 suffused with ochraceous, and with very dark underfur. 



General colour above between chestnut and vandyke brown, the 

 hairs except at the tip being slate-black. Flanks and sides a rich
