282 ON NEW ANIMAL PARASITES. [Mar. 19, 



slides and large series of photographs and specimens, on recently 

 discovered subfossil Prosimite from Madagascar, in which he dis- 

 cussed their affinities with extant Lemurs and with the higher 

 Primates. The remains were obtained in the muddy bed of a swamp 

 formed by the blocking-up of the river Mazy by a lava-flow, at from 

 a few inches to 3 or 4 feet below the surface. They consisted of 

 a large number of skulls and limb-bones of Lemurs and Lemur- 

 like animals. This great amount of material enabled the author 

 to corroborate the view, previously put forward by Dr. Forsyth 

 Major, that the extinct Lemurs of Madagascar were, in many 

 respects, intermediate between existing Lemurs and Monkeys, 

 and to express his belief that the New World Monkeys and the 

 Lemuridee, as well as the Malagasy Indrisinse, had a common origin. 

 He also stated his opinion that, in view of the recent additions to 

 our knowledge of the Prosimiee and of what the present collection 

 revealed with regard to their close relationship to the Apes, it 

 was not possible to separate the Primates, as hitherto, into the 

 two sviborders Lemuroidea and Anthropoidea.
