35 a. Ophiopeza conjungens, Bell. Specimens are known 

 fronn the northern parts of Australia and from the " Indian Ocean " ; 

 thanks to Mr. Oates's gift I am able to give a definite point in the

[Eeceived January 15, 1889,]

 of Rhinoceros sumatrensis, one of which died on April 22, 1885 ; the 

 other on the 26th of October of last year. The two individuals
