to a genus of Coleoptera. I therefore change it to Tawongia, after 

 the locality where the type specimens described were obtained. 



In conclusion, I cannot too gratefully express my thanks to 

 Mr. E. I. Pococlc, of the British Museum Natural History Depart- 

 ment, for kindly advice and ready assistance always at my service, 

 and in allowing me access to the Collections under his charge ; 

 without which it would have been impossible fcr me to have in- 

 vestigated many points of interest and doubt, some of which I 

 trust I have been able to make clear. 



June 18, 1901. 

 Prof. Gk B. Howes, LL.D., E.E.S., V.P., in the Chair. 



The Secretary read the following report on the additions to the 

 Society's Menagerie during the month of May, 1901 : — 



The total number of registered additions to the Society's Mena- 

 gerie during the month of May was 226, of which 23 were by 

 presentation, 7 by birth, 16 by purchase, and 180 were received on 

 deposit. The total number of departures during the same period, 

 by death and removals, was 150. 



Amongst the additions attention may be called to : — 



1. Four hybrid Macaws bred at Milan, in Italy, between a male 

 Bed-and-Blue Macaw (Ara macao) and a female Military Macaw 

 (Ara militaris). These birds have been deposited under our care 

 by the Hon. W. Eothschild, M.P., P.Z.S. This is, so far as I 

 know, the only instance on record of hybridism between two 

 species of Macaw in captivity. 



2. A young male African Elephant (Elephas africanus), pur- 

 chased ou May 21st. This animal was imported from Massowah, 

 and is said to have been captured in the Italian colony of Eritrea. 

 It is about four feet high, and is presumed to be about four years 

 old. 



3. A Guilding's Amazon (Chrysotis guildingi) from St. Vincent, 

 presented by the Earl of Crawford, E.Z.S., on May 25th. This 

 addition renders our series of the peculiar Amazons of the Lesser 

 Antilles complete. We have now in the Parrot House specimens 

 of four species of these Amazons, viz., Chrysotis guildingi from 

 St. Vincent, O. augv.sta and bouqueti from Dominica, and C. versi- 

 color from St. Lucia. 



4. A male Bed-flanked Duiker (Cephalophus rufilatm) from 

 West Africa, presented by M. Th. Leportier on May 28th. We 

 have received no specimen of this Antelope since 1880. 



Two skulls and the skin of the ne\ Mammal, the Okapi, dis- 

 covered by Sir Harry Johnston, K.C.B., E.X.S., which had been 

 sent to the Natural History Bduseum, were exhibited, and the 

 following remarks, by Prof. E. Bay Lankester, F.B.S., E.Z.S., were 

 read : —
