Tlir (Vt(]iiii(lae 1)1' l)r. IJayon's collection, that liavc lircn iilaccd 

 ill my liaiids for (letcrmination by nij' esteemed friend Dr. (l(stn), 

 conijirise forty-three sj)ecios, thirty-two of these are already known 

 to occur in tlie West Coast and lower Congo region, thus shewing 

 the very close similai'ity of tlie fauna of Uganda to tliat of ^^'est 

 Africa. Tlie liigli land of the Escarpment is ajipan ntly tlie western 

 boundary of tiie true Kast African fauna, and it seems remarkable 

 that tile i-aiige of scarcely any of the species of that regicju extends 

 into Cganda. The most interesting of Dr. Bayou's discoveries is a 

 very remai'kable new form in the Cremastocheilides possessing 

 six-jointed antei'ior tarsi.
