views upon the position of Stringops. He regards it, it is ti'ue, as 

 a member of a subfamily (^Stringojnnce) dii&imctivova. the Cacatuince', 

 but both these subfamilies are witbiu one family, Palceornithidce. 

 We quite agree with Prof. Garrod's remark about Stringops (P. Z. S. 

 1874, p. 596) that " as a Parrot it is not so strikingly peculiar as 

 many seem to think. Its wings are useless, and the carina sterni 

 is correspondingly reduced, it is true ; but as points of classifica- 

 tioual importance, I regard these as insignificant." 



The association of Cacaiua with Microglossa and CalyptorliyncJius 

 is confirmed, though Cacatna is perhaps farther off either of these 

 two than they are from each other. 



Ara, too, we find to be rather nearer than some have thought it 

 to certain of the Old World genera, such as Nestor, Stringops, and 

 Calyptorhynchus. Considering the superficial resemblance which 

 the Maca^^"s bear to the Cockatoos, this result is of not a little 

 interest.

[Eeceived June 2, 1893.] 



My friend Mr. Frederick Holmwood, C.B., C.M.Z.S., H.B.M. 



Consul-General at Smyrna, has kindly lent me for examination two 

 very remarkable horns of an African Rhinoceros, which he obtained 

 at Zanzibar, when Consul-General there a few years ago. Mr. 

 Holmwood gives me the following account of them : — 



" From a very careful description of the country I gathered that 

 they came from the country of ' Udulia,' situated at the N.E. 

 point of Usukuma, 50 miles S. of Speke Gulf. The native traveller 

 whom I bought them of thought, however, that the district, which 

 is a jungle interspersed with grassy plains, might form part of 

 the large pastoral country to the W. of Udulia, called by various 

 names, but known generally by caravans as ' Uturu.' He said it 

 was the only district where this Rhinoceros was known. It is only 

 inhabited by hunters whom he described as dwarfs, but I do not 

 take this for granted."
