At once recognizable from C. Johnstoni, Pocock (Ann. & 

 Mag. Nat. Hist. (6) xx. p. 253, figs. 1, 1 a), from Nyasaland, 

 and from C. ornatum, Karsch (=C*. variatum, Pocock, Proc. 

 Zool. 8oc. 1898, ]). 523, pi. xlii. fig. 16, c?), from Masailand, 

 by the shortness of the ffagelkuu, the nearly uniform pale 

 colouring, greater length of appendages, &c.* 



« In .lahrb. Ilanib. Wiss. Aii&t. xvi. p. 247 (1899), Kiaepeliii cites 

 nnion};st the rt'cogiiized species of Ceroma two forms named Cen»ita 

 I'iclaiiri and Ceroma capense, both purporting to be described by 

 Dr. Purcell, of the South African Museum, Cape Town. I cannot 

 discover tiuit tlie descriptions of these species have yet been published. 

 It is a thousand pities that noniina nuda should make their appearance 

 in literature in this way.
